How To Predict New Moon | Using Any Space App

There are many apps available in stores to watch the night sky and observe every detail of heaven. You can also calculate the rising and setting time of the celestial objects using these applications or you can identify planets and stars through them. For Prediction of a new moon, I used a complete data-based website named, Fourmilab. It has the collection of all the celestial objects in the sky with their current coordinates.

CELESTIAL OBJECT:

Earth’s Moon/ Luna

DESCRIPTION:

The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite.

AGE & FORMATION:

The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. The most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body.

APPARENT SIZE & ORBITAL ROTATION:

The Moon is in synchronous rotation with Earth, and thus always shows the same side to earth, the near side. The Moon's average orbital distance is 384,402 km or 1.28 light-seconds. This is about thirty times the diameter of Earth. The average orbital speed is 1.022 Km/s. The Moon's apparent size in the sky is almost the same as that of the Sun (because it is 400x farther and larger). Therefore, the Moon covers the Sun nearly precisely during a total solar eclipse.

LUNAR CYCLES:

SIDEREAL MONTH:

The time it takes the moon to orbit once around the earth with respect to the stars (approximately 27.3 days).

SYNODIC MONTH:

The time it takes from new moon to new moon with respect to the Earth (approximately 29.5 days) However, because the Earth is constantly moving along its orbit about the Sun, the Moon must travel slightly more than 360° to get from one new moon to the next. Thus, the synodic month, or lunar month, is longer than the sidereal month. A sidereal month lasts 27.322 days, while a synodic month lasts 29.531 days.

Equatorial Coordinate System

This is the preferred coordinate system to pinpoint objects on the celestial sphere. Equatorial coordinates are independent of the observer’s location and the time of the observation. This means that only one set of coordinates is required for each object, and that these same coordinates can be used by observers in different locations and at different times.
The equatorial coordinate system is basically the projection of the latitude and longitude coordinate system we use here on Earth, onto the celestial sphere. By direct analogy, lines of latitude become lines of declination (Dec; measured in degrees, arcminutes, and arcseconds) and indicate how far north or south of the celestial equator (defined by projecting the Earth’s equator onto the celestial sphere) the object lies. Lines of longitude have their equivalent in lines of right Ascension (RA), but whereas longitude is measured in degrees, minutes and seconds east the Greenwich meridian, RA is measured in hours, minutes and seconds east from where the celestial equator intersects the ecliptic (the vernal equinox). There are 360°/24h = 15° in one hour of right ascension, 24h of right ascension around the entire celestial equator.

NEW MOON:

The initial period, as only the thinnest sliver of a Crescent The moon becomes visible, used to be called New Moon. From scale: Comparing the rotation of the moon in Right Ascension and Earth Time. ET 24h = RA 56m ET 1h = RA 2m 16s It means the moon moves 2m 16s (RA) every Earth hour with respect to the celestial sphere.

BIRTH OF THE NEW MOON:

Right after the moon passes in front of the sun, the moon begins to be in its birth phase. However, people from the earth cannot observe this phase because the far side of the moon is fully illuminated and the near side is completely dark.

VISIBILITY OF THE NEW MOON:

The waxing crescent is said to be the new moon. The higher expectancy to observe the crescent with naked eyes is 20 hours minimum from the birth of the new moon and the difference of 40-50 minutes in the sunset and moonset (Recorded time for Pakistan). However, the weather condition and the visibility duration can make it difficult to see the youngest moon. This new crescent can be observed right after the sunset in the direction of the West. The direction might change slightly due to the axial tilt of the Earth throughout the year from West, Northwest (WNN) to Southwest (WSW).

Can you identify the planets in the night sky?

Can you identify the planets in the night sky?

If you have never studied astronomy or somehow have little knowledge about up sky heaven, then you are not able to identify planets in the night sky. Have you ever wondered how the planets look like from our Earth? I’m sure you have never noticed the bright shiny object in the sky. It seems to be a star in the night sky. But it is brighter than the usual star can be seen in the below picture.

Let me acknowledge you about some facts by which you can easily differentiate between planets and stars in the night sky.

First of all the general definition of both the object which may everyone know.

The Planets:

A celestial body moving in an elliptical orbit around a star. A planet is a large object such as Jupiter or Earth that orbits a star. Planets are smaller than stars, and they do not produce light. A star and everything which orbits it are called a star system. There are eight planets in our Solar System.

The Stars:

A huge ball of gas held together by gravity. The central core of a star is extremely hot and produces energy. Some of this energy is released as visible light, which makes the star glow.

How to Distinguish Between stars and Planets in the Night Sky

• One of the easiest ways to Distinguish between stars and planets in the night sky is by looking to see if the object twinkles or shimmers. This can usually be detected with the naked eye if you have a clear view of the sky.

• Planets rise in the East and set in the West. They tend to follow a similar celestial path across our sky as the sun and moon.

• Planets are always found along an imaginary belt across the night sky called the ecliptic. This belt is not actually a visible object. The easiest way to find the ecliptic is to note the location and trajectory of the sun and moon in the sky relative to your location on the Earth. The sun's path across our sky is very close to the path of planets along the ecliptic.

• Stars may also appear along ecliptic but Mercury, Venus, Mars, Jupiter, and Saturn are significantly brighter than the surrounding stars. This is due to their proximity to the sun since their "brightness" is just reflected sunlight.

Why do stars twinkle?

Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. Stars are so far away from Earth that, even through large telescopes, they appear only as pinpoints.

When starlight enters our atmosphere it is affected by the movement of air in the atmosphere of Earth (atmospheric layers have different temperatures and densities).

This causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. This means that some of the light reaches us directly and some gets bent slightly away. To our eyes, this makes the star seem to twinkle.

You can clearly observe them from binoculars or a telescope so grab one and enjoy.

Why Eclipses Do Not Occur Every Month?

2019-05-01T17:49:00.004+05:00

Why Eclipses Do Not Occur Every Month?

If moon orbit is perfectly aligned with Earth, we get a solar eclipse every new moon and a lunar eclipse every full moon. But we don’t because Moon’s orbit is tilted 5° with respect to Earth.

Eclipse:

"Eclipse is an obscuring of the light from one celestial body by the passage of another between it and the observer, or between it and its source of illumination".

Phases of The Moon:

The phases of the Moon are caused by its orbital motion

The phases of the Moon occur because light from the Moon is actually reflected sunlight. As the relative positions of the Earth, the Moon, and the Sun change, we see more or less of the illuminated half of the Moon.

Time and the Moon:

Two types of months are used in describing the motion of the Moon.

1. With respect to the stars, the Moon completes one orbit around the Earth in a sidereal month, averaging 27.32 days.

2. The Moon completes one cycle of phases (one orbit around the Earth with respect to the Sun) in a synodic month, averaging 29.53 days.

Moon’s Orbit and Ecliptic:

Eclipses occur only when the Sun and Moon are both on the line of nodes. You can understand the line of nodes from this picture clearly.

Three types of Lunar Eclipses:

Lunar eclipse- caused by the earth’s shadow covering the moon. There are two parts to the shadow- umbra and penumbra.

Umbras and penumbras are the names for two kinds of regions in a shadow that have different amounts of light in them. An "umbra" is the part of the shadow where all of the light from the source is blocked by the shadowing object. A "penumbra" is that region around the umbra where the shadow is only partial, or imperfect. You get these when the light source is larger than a single point.

Lunar eclipses can be either total, partial, or penumbral, depending on the alignment of the Sun, Earth, and Moon.

Penumbral lunar eclipse the Moon only passes through the penumbra of Earth’s shadow. Partial lunar eclipse part of the Moon passes through the umbra of Earth’s shadow. Total lunar eclipse the entire Moon passes through the umbra of Earth’s shadow. Can last for nearly for two hours.

Do you know the reason for Solar Eclipse?

Do you know the reason for Solar Eclipse?

Many of us don't know how the Eclipses occur so here is the detail of Solar Eclipse.

Solar Eclipse caused by the moon making a small shadow on the Earth. Solar eclipses can be either total, partial, or annular, depending on the alignment of the Sun, Earth, and Moon.

Remember that it is not safe to stare at a solar eclipse! Try these gadgets for safety.

Total and Partial Solar Eclipse:

The moon creates a small shadow which Only allows certain areas of the earth to see a total solar eclipse.

Observers in the “umbra” shadow see a total eclipse (safe to view the Sun). They can see the corona and those who are in “penumbra” see a partial eclipse which is not safe to look directly on Sun. Total Solar Eclipse lasts for a few minutes. You can understand the terms "Umbra" and "Penumbra" in the below picture.

The Path of Totality is the area covered by the shadow of the moon about which is about 10,000 miles long and only 100 miles wide

Annular Solar Eclipse:

When the Moon is too far to completely cover the Sun the umbra doesn’t reach the Earth. Sun appears as a donut around the Moon.

The apparent size of an object in the sky depends on how big it is and how far away it is. When the moon is close to the Earth, is called Perigee and when the moon is far away from Earth, is called Apogee.

The sun is about 400 times wider than the moon, surprisingly on average, it is 400 farther than Moon. So, being these number equals the Sun and Moon appear to about the same size in the sky.

Cause of Lunar Eclipse will be soon here so stay tuned!

The First Ever Image Of A Black Hole | How they are formed

2019-04-10T20:24:00.001+05:00

The First Ever Image Of A Black Hole

The first-ever image of a black hole is now revealed. it is taken by the event horizon telescope (EHT). the supermassive black hole pictured is at the center of Messier 87,

a massive elliptical galaxy in the constellation Virgo. it is located 55 million light years from earth and has a mass 6.5 billion times larger than our sun. this is a huge achievement, not only because it confirms Eintsines general theory of relativity, but because it opens up the possibility for visual observation of a black hole immediate environment.

Do you know what are black holes and how do they form?

Most people think of a black hole as a voracious whirlpool in space, sucking down everything around it. But that’s not really true! A black hole is a place where gravity has gotten so strong that the escape velocity is faster than light. But what does that mean, exactly?

For the Earth, that velocity is about 11 kilometers per second (7 miles/second). But an object’s escape velocity depends on its gravity: more gravity means a higher escape velocity because the gravity will “hold onto” things more strongly.

The Sun has far more gravity than the Earth, so its escape velocity is much higher more than 600 km/s (380 miles/s). That’s 3000 times faster than a jet plane!

If you take an object and squeeze it down in size, or take an object and pile mass onto it, its gravity (and escape velocity) will go up. At some point, if you keep doing that, you’ll have an object with so much gravity that the escape velocity is faster than light. Since that’s the ultimate speed limit of the Universe, anything too close would get trapped forever. No light can escape, and it’s like a bottomless pit: a black hole.

How Black holes Are Formed

The most common way for a black hole to form is probably in a supernova, an exploding star. When a star with about 25 times the mass of the Sun ends its life, it explodes.

The outer part of the star screams outward at high speed, but the inner part of the star, its core, collapses down. If there is enough mass, the gravity of the collapsing core will compress it so much that it can become a black hole.

When it’s all over, the black hole will have a few times the mass of the Sun. This is called a “stellar-mass black hole”, what many astronomers think of as a “regular” black hole. But there are also monsters, called supermassive black holes.

These lurk in the centers of galaxies, and are huge: they can be millions or even billions of times the mass of the Sun! They probably formed at the same time as their parent galaxies, but exactly how is not known for sure. Perhaps each one started as a single huge star which exploded to create a black hole and then accumulated more material (including other black holes).

Astronomers think there is a supermassive black hole in the center of nearly every large galaxy, including our own Milky Way. Stellar-mass black holes also form when two orbiting neutron stars, ultra-dense stellar cores left over from one kind of supernova merge to produce a short gamma-ray burst, a tremendous blast of energy detectable across the entire observable Universe. Gamma-ray bursts are in a sense the birth cries of black holes. Try these Astronomy gadgets:

Ancient Egyptian Achievements in Astronomy

The old Egyptian progress was one of the first and most prominent civic establishments all in all world and the way that the old Egyptians had done numerous accomplishments which secured most sides of the human life, including the political and social upgrades, also, their advances in numerous science majors. We should speak now about what they have accomplished in the study of cosmology.

The Egyptians were extremely intrigued by the stars and heavenly bodies and they gave much enjoy that energizing science. From the Center Kingdom, heavenly bodies were regularly delineated on pine boxes as star timekeepers, demonstrating the period of time stars were unmistakable or undetectable.

From the New Kingdom, roofs of tombs and sanctuaries frequently showed the heavenly body of stars. These heavenly bodies were equivalent to the ones we see today however spoke to in an unexpected way. For instance, Orion was spoken to as a man turning his head and Ursa Major was spoken to as a bull's foreleg. From the Center Kingdom, the Egyptians had the capacity to perceive five planets, known as stars that know no rest, which was regularly connected with Horus, the Egyptian lord of the sky:

* Jupiter, known as Horus who restrains the two grounds
* Mars, known as Horus the red
* Mercury, known as Sebago (a divine being related with Seth)
* Saturn, known as Horus, bull of the sky
* Venus, known as the divine force of the morning

The antiquated Egyptians had utilized space science for a wide range of pragmatic sides..and a standout amongst their best accomplishments was setting the new year dependably to correspond with the ascending of Sirius in mid-July and the yearly flooding of the Nile.

Flooding was going on consistently and in the meantime. The antiquated space experts and clerics saw that the flooding dependably happened at the late spring solstice, which likewise coincidentally was the point at which the splendid star Sirius ascended before the sun thus, they had the capacity to anticipate the yearly flooding, expertise which thusly rendered them extensive power. At that point, they separated the year into a year of 30 days, trailed by a multi-day feast period.

Likewise, the Egyptians utilized cosmology in planning sanctuary building functions, which depended on the permeability of the heavenly bodies we allude to now as the Incomparable Bear and Orion too, they could set the cardinal focuses for the introduction of the pyramids by watching the North Star. At long last, say that the stars were not used to anticipate the destiny of people in Egypt until the Ptolemaic time frame when the Greeks presented crystal gazing. The most acclaimed zodiac in Egypt is on the roof at Denderah and dates to the main century Promotion. This zodiac shows all the natural zodiac signs, including Leo, Aries, and Taurus.

Do you know the mystery of day and night at poles?

Are you living near the Earth's pole? If no, then you may not know the mystery at the poles. have you ever experience a day of 20 hours or a night of 20 hours? yes, it happens near the south and north pole. Astronomically we call it Midnight sun in which the sun appears all the time at the sky for 6 months and then the darkness of night grab that region for 6 months.

What is Midnight sun?

What are polar day and polar night? The midnight sun is when at least a part of the Sun's disk is visible above the horizon 24 hours of the day. The scientific name for midnight Sun is polar day and the opposite is the polar night.

As the upper edge of the solar disc disappears below the horizon, the Sun has set, and there is no longer midnight Sun. The moment the solar disc again becomes visible above the horizon, it is sunrise. In the Northern Hemisphere, the midnight Sun starts on the North Pole as the Sun rises around the vernal (spring) equinox in March.
Then there is midnight Sun for about six months.

The Sunsets again around the autumnal (fall) equinox in September, entering six months of polar night. In the Southern Hemisphere, it is the opposite. There are polar nights when the Northern Hemisphere has polar days.

Even though Norway is known as the "Land of the Midnight Sun" in the tourist industry, there is midnight Sun in several other countries in the Northern Hemisphere: USA (Alaska), Canada, Russia, Greenland, Finland, and Sweden.

Do you know the myth about shooting stars?

2019-03-08T19:46:00.000+05:00

Do you know the myth about shooting stars?

Most of us probably have seen or heard about shooting stars. But no one wonders if it is actually a shooting or dying star or something else about which many of us have a misconception. If you think like everybody else about shooting stars so you are totally wrong.

So what exactly it is?

A shooting star is not a star but a meteor. A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris (space junk) burns up as it passes through our atmosphere. "Meteor" refers to the flash of light caused by the debris, not the debris itself.

The debris is called a meteoroid. A meteoroid is a piece of interplanetary matter that is smaller than a kilometer and frequently only millimeters in size. Most meteoroids that enter the Earth's atmosphere are so small that they vaporize completely and never reach the planet's surface.

What if shooting star reaches the Earth?

If any part of a meteoroid survives the fall through the atmosphere and lands on Earth, it is called a meteorite. Although the vast majority of meteorites are very small, their size can range from about a fraction of a gram (the size of a pebble) to 100 kilograms or more (the size of a huge, life-destroying boulder).

You can also see these kinds of beauties of heaven with your cool gadgets which you can buy from here:

More similar things are there in space!

Asteroids are generally larger chunks of rock that come from the asteroid belt located between the orbits of Mars and Jupiter. Comets are asteroid-like objects covered with ice, methane, ammonia, and other compounds that develop a fuzzy, cloud-like shell called a coma and sometimes a visible tail whenever they orbit close to the Sun.

Are you curious about the up-sky heaven?

2019-03-04T20:24:00.001+05:00

Are you curious about the up-sky heaven?

The star-lit sky is one of nature's most amazing displays that most of us have taken for granted. We have become very busy in our lives that we usually have no time to look at the heavens above us, neither we are curious about up-sky heaven. We are already dead tired at the end of the day. In addition, most of us live in urban areas where the city lights have outshined the stars and only those in the countryside have the advantage of crystal clear view of the spectacular show.

Some people have been inspired by these cosmic phenomena to either start a career in astronomy or engage in a hobby. Astronomers, physicists, and other scientists have begun their quest for space exploration by just looking at the stars in the night sky.

They have a never-ending curiosity on how the solar system, stars, and other foreign bodies came into being. Their efforts have given us the knowledge of how the universe as a whole gave way to our own existence. Beginners have looked at the sky and stirred up great desire to learn more about the heavens in their own way. It is not surprising that these space hobbyists at the past and present were able to discover previously unknown planets, stars, and galaxies. They have even predicted certain changes in space that scientists have overlooked in their observations.

Your passion for astronomy may have started from a feeling of awe that you experienced at a camping trip with your friends. A total solar eclipse may have got you scrambling outside your home to watch it. There a lot of sightings that inspired many people to start this sky-gazing hobby.

A growing amateur astronomer such as you should read various books regarding astronomy. There are reading materials that can be found in public libraries and even on the internet. Among the most important things to note during your research is to know the orbits of planets in the solar system and the position of the stars at different times of the year. Nevertheless, the experience is the greatest teacher that will enable you to learn more about celestial objects. You need to invest in equipment that will give you a clear vision of space at night. A constellation map is also a vital tool in charting the various formations of stars seen in the sky.
For starters, a good set of astronomy binoculars can be used in stargazing. Be sure to acquire one that is suited for this purpose because these are very comfortable to carry around. This gadget also has unique features that can zoom in images of stars and other planetary bodies. As you conduct even more comprehensive research on astronomy, specialized and long-sized personal space telescopes are recommended. However, you don't need to buy the most sophisticated ones in order for you to enjoy your hobby. Look for those that are affordable and can function well.
There are times when you want to go to different places to observe the formation of stars as well as rare phenomena such as solar and lunar eclipses. Hence, you should also ensure that the device can withstand long-term use and for adverse conditions. Of course, no one can stop you from owning the ultimate telescope system. However, you need someone who has specialized knowledge of its operation. A few tweaks were done on the instrument and you can spend long hours watching the heavens beyond the naked eye and towards the unknown.

Learn a Little More About Astronomy

Astronomy is one of the most interesting subjects. The world of planets and stars is certain to leave anyone amused. Although man has been studying astronomy for several years now, there are still a lot of facts about the subject that remains relatively unknown. Let us take a look at some of them.

One of the most surprising facts about astronomy is that you cannot see everything around. As per scientists, we can only see 5% of the matter that is around us. The rest of the matter is made up of invisible matter, which is also called dark matter.

We know that the Sun is the prime source of energy of our planet. But, we are completely unaware of the fact that its center generates energy in huge quantities every second which is equal to the energy of billions of nuclear bombs combined.

It is quite expected that the planet Mercury, being the closest to the sun must have rising temperatures. However, quite surprisingly, the temperature of this planet could easily drop down to -280 degrees F. Such a drastic drop in temperature may be attributed to the fact that Mercury lacks atmosphere, which makes it impossible for the planet to trap any heat as coming from the sun. No wonder the face of this planet away from the sun is colder.

Buy some cool gadgets for Astronomy here:

On the contrary, Venus that is comparatively far away from the sun is warmer. This is simply because of the fact that the atmosphere of Venus is much thicker, which traps the heat. As a result, Venus has a tendency to be warmer.

Whenever we are asked about the inventor of the telescope, we always credit it to Galileo Galilei. But, the fact is that Galileo used the tool to study the stars first. Historians and researchers believe that it was the invention of Johannes Lippershey, a Dutch eyeglass maker. You can also try and use the telescope to observe several heavenly bodies including the moon.

The shooting stars that we see in the sky are nothing but dirt particles. When comets go through the earth's environment, they leave a trail of dust at the back. When this particle moves through the environment, they heat up. This creates bursts of light in the sky which appears as a shooting star.

Looking For Astronomy Gifts? Sleep Under The Stars Every Night

Looking For Astronomy Gifts? Sleep Under The Stars Every Night!

From the moment we are born, astronomy gifts, glow in the dark stars and star themed lullabies are thrust upon us. 'Twinkle twinkle little star' is sung or played repeatedly to all babies and every piece of equipment and clothing aimed at small children has themes of stars and moons. This is no wonder, as the heavens have inspired and fired imaginations throughout mankind's history. Astronomy gifts, including glow in the dark stars, are some of the most popular presents for young and old alike.

Every child loves getting astronomy gifts, as outer space holds no limits for their imagination. Hours of fun can be had, pretending to be an astronaut and exploring new planets and galaxies. Even as adults, we still stop and stare in wonder, when we are lucky enough to view a star-filled sky at night. It is such an amazing and beautiful sight! Studying the stars can be a lifelong hobby. My father used to spend many evenings pointing out the different constellations to me, and this habit encouraged me to purchase my first telescope as a teenager.

Buying the right astronomy gift is a problem as with the air pollution that we all suffer from in large cities, visibility is poor, so viewing the stars with the naked eye is practically impossible.

Even with my telescope, I struggle to view even the closest stars. I found this to be extremely frustrating, as I wanted to pass the gift of astronomy knowledge onto my children.

Apart from moving away from the city, the only way to view the stars every night is to find some way of bringing the stars into your home. It is possible to find specialized interior designers or artists that can paint glow in the dark stars directly onto your ceiling. This is extremely beautiful but also very expensive! Another alternative is to purchase glow in the dark plastic stars. These can be bought easily online, but don't give a realistic impression of the night sky and children can learn nothing about constellations, planets or meteors.

The most beautiful and educational astronomy gift is to purchase a 'Glow in the dark ceiling poster'. These are marvelous as they glow all night long, showing the constellation of your choice, and can be placed directly above your bed, so the illusion of sleeping under the stars is complete. Glow in the dark ceiling posters is very affordable.

These ceiling posters are also available with shooting stars, angels and spaceships. They come in various sizes and will last for years! Absolutely perfect astronomy gifts for everyone in your family. You and your child can spend many a happy hour stargazing every night, from the comfort of your own bed.

Astronomy Binoculars - 5 Tips For Best StarGazing Equipment And Techniques

2019-02-25T20:54:00.000+05:00

Astronomy Binoculars - 5 Tips For Best StarGazing Equipment And Techniques

Astronomy binoculars can be a valuable resource for the amateur astronomer. With a good set of binoculars, you can see a wide range of stars and other objects. This article provides five tips to help stargazers get started in viewing the heavens.

1) Get a good handbook

Many hobbies have excellent reference works. Two good books for learning how to use astronomy binoculars are "Touring The Universe Through Binoculars" by Philip Harrington, and "The Binocular Stargazer" by Leslie Peltier. These reference works provide helpful tips to the beginner and experienced stargazer alike.

2) Get a center focusing wheel

Once you have identified a star watching target, focusing your binoculars is the most important operation to getting the best view of your target. A center focusing wheel will give you the most control in getting the sharpest image for your observation.

3) The wider the field of view, the greater the light

Astronomy binoculars seek to gain the most

light possible from the dim stars and other heavenly objects. A wide field of view means that the lenses used are able to collect light from a larger portion of the sky. More light will help you get the most from your observations.

4) A tripod will keep the view steady

Photographers often use a tripod to steady their camera when taking photos of a fixed setting. Constellations of stars are also relatively fixed for the time duration of most astronomical viewing. Using a tripod will keep your view steady as you try to make out the various star patterns.

5) Inspect your binocular features before purchase

You will have done a lot of research to make sure that the model of binoculars you are selecting meets your requirements. Inspecting the features of your binoculars before purchase will ensure that you are satisfied with the selection.

Backyard Astronomy Without a Telescope

Are you looking to do backyard astronomy? You may be stuck in a problem. No telescope and you still want to do backyard astronomy! In this article, you will discover some astronomy experiments you can do without the need for a telescope.

The first thing we see, when we look up at the sky, is lots of shining points of light. These points of light seem to make up patterns, and these patterns are what we call constellations.

There are 88 in total that is visible from the Earth. These constellations have such an old meaning to us, that we still have birth signs. Your birth sign is one of those 88 constellations.
Constellations are made up of a group of objects in space. This makes looking at constellations, one of the greatest things to do. Imagine, knowing where these 88 constellations are.

You could literally take any rough coordinate for a star or object in the sky, and manage to navigate to it, much more easily. And all this because you learned about the constellations.
Many myths have been gathered up with the constellations.

From the great hunter to the story of the scorpion, looking at the constellations teaches us much more than simply knowing the layout of space!

Many early astronomers started with no tools at all, apart from using what they had their own kind of telescope, their eyes! And still managed to invest a lifetime into astronomy.

A telescope still does help, and once you do have a telescope, you likely will prefer the telescope than simply looking up at constellations. However, there is always that fascination with constellations.
A group of astronomers all puts in their life research into space to find those constellations which many today take for granted. These constellations have helped countless navigators at sea, be able to do their voyages.
Now you can do in the same way, by learning about the constellations. There is a lot to learn about the constellations. Such information that can be learned from constellations and backyard astronomy is the shape, the size, the number of stars or objects that make up the constellation.

You could also look at when these objects appear in the sky, and when they are no longer there. It is easy to look up this information in a book, but when you start doing proper backyard astronomy and find out these truths for yourself. Suddenly you have a strong sense of satisfaction, as you now know that you are really taking part in science.

A good idea is to keep a notebook. Draw pictures, write down your findings. Over time this can be a great way to see your progress in backyard astronomy.

Here are some telescope resources that can help you find and buy a telescope:

Astronomy Tool - Green Laser Pointer

With the hot summer coming, nightlife has become one of the major themes of a day. Summer is the best season for astronomy researchers and fans to watch constellations in the night sky.

Astronomy laser pointer might be a wonderful tool for those astronomy fans to have clear stargazing and targeting. If you know little of laser diode technology about the application in astronomy, I hope these tips might be helpful. The fist is the color of a laser beam.

Various kinds of green, red, blue, yellow, violet color lasers are all available in the market, while what kind of color should you choose?

For astronomy, high brightness and long distance visibility are two major factors to be paid attention

to. Green laser pointer has a medium wavelength of 532nm and the most sensitive color, so the beam of the green laser diode has better diversity than any other colored laser diode device. As a result, the green color laser diode has become the first choice of stargazing and pointer for astronomers.

Second is laser output power.

Astronomy grade lasers are available from 5mW to 150mW so you can have a free choice of a suitable laser you need. The low power 5mW is usually used in a good atmosphere and for short distance observations. In the condition of bad atmosphere, higher power laser is required so as to have long visibility of celestial objects. You can choose laser pointers depending on the actual conditions.

Third and also the most important of all should be the quality.

Low power has become the most competitive advantage of any commodity, thus it is a difficult thing to make sure of the reliable quality. A high reputation laser supplier will no doubt provide astronomy lasers with the best quality. Only laser pointers with a high bright beam and good quality can really have a good effect of star gazing and other astronomy researches.

If you are an astronomy enthusiast, a cheap astronomy laser pointer is a perfect tool for your stargazing. You will have a good time during this hot season and enjoy yourself with the perfect astronomy tool - Green Laser Pointer

Astronomy The Real Star Power

2019-02-22T23:14:00.000+05:00

Astronomy The Real Star Power

Ever watched out the window around evening time and end up gazing at the universe, pondering what is up there? This has been an exceptionally basic inquiry among people since the beginning of time since progress initially existed. From the Nubian Monuments to the Egyptian Monuments and Stonehenge, these are archeological confirmation from the past that galactic examinations have been a typical enthusiasm among humanity all through the ages.

Stargazing basically is the exploration of considering items and

wonders in space, for example, anything outside the world's climate.

Until telescopes were developed in the seventeenth century, cosmology as we probably are aware was restricted to simply gazing upward into the sky with our exposed eyes. Since the creation of telescopes, Astronomy has fragmented off into another field of study which considers more inside and out the material

science of heavenly items frameworks, Astrophysics. Cosmology and Astrophysics are basically interwoven in light of the fact that one can't exist without alternate in this way which has prompted huge walks in the Astronomy field.

A short history of Astronomy

Astronomy is the endless investigation of our universe, or Multi-section contingent upon the physicist, and each divine item in it. Antagonistically, this incorporates planets, space rocks, comets, stars, gas developments, dark openings, and different universes. Cosmology is regularly mistaken for Astrology, which is the conviction that people are by one way or another interconnected with the arrangement of stars. In spite of the fact that the sources of the two investigations are firmly related, the real subjects themselves are a long way from the equivalent. Cosmology is all the more firmly related to Astrophysics. While stargazing thinks about depending on the disclosure and development of divine bodies, Astrophysics concentrates more on the investigation of the improvement, arrangements, and science of the known universe. Without cosmologists, the astrophysicists would not have new disclosures to think about and without the astrophysicists, the stargazers would have no inspiration to hold looking to the skies. The two sciences essentially rely upon one another.

It is trusted that in before developments structures, for example, Stonehenge was worked so as to foresee the changing of the seasons. In view of the situating of specific articles in the sky's arrangement with the steady structure, the general population would know when the best time was to plant or collect yields. A lot more headways were made in the field of Astronomy when telescopes were imagined. The logical unrest started when splendid personalities, for example, Nicolaus Copernicus, Johannes Kepler, and Galileo Galilei started looking to the skies amid the season of the Renaissance. Had it not been for them and Issac Newton's law of attractive energy, the working learning of the universe we have today would not exist. Newton likewise concocted the seventeenth-century option in contrast to the refracting telescope, the reflecting telescope. Since the refined work of these early stargazers and astrophysicists, we have possessed the capacity to demonstrate the Earth is in its own gathering of stars which is the only one-star framework in our own special Milky Way system. Likewise, in the twentieth century, the general development was demonstrated alongside the broadly sponsored speculations of enormously colorful items, for example, dark gaps and neutron stars. Quick forward to the 21st century and the field of Astronomy is perfectly healthy more than ever. With the assistance of the incredible Hubble space telescope, which as of late found another water-filled planet only 40 light years away to crafted by the astrophysicist endeavoring to understand the staggering subject that is the universe, I have no uncertainty Astronomy will keep on being of extraordinary enthusiasm for the time being and the not so distant, fascinating my age and the future ages to come, also too that it is additionally a phenomenal side interest to which it has been for a mind-blowing duration, from youth to adulthood.

Dan Wilson has been infatuated with Astronomy since the first occasion when he looked into the sky and saw his first star at the young age of 9. A maturing novice space expert, Dan is intrigued by the Universe, and it is that interest that he needs to impart to you.

Why not go along with him on a voyage of disclosure into the universe at his very own little site which he made as a spot to express his profound enthusiasm of Astronomy.

Astronomy Is a Great Hobby!

2019-02-22T23:03:00.001+05:00

Astronomy is a Great Hobby!

Astronomy must be one of the most lowering of all subjects to ponder. Simply the prospect of our universe, resembling a grain of sand in a sandy shore of universes, is sufficient to make me need to slither back under the sheets. Everything just appears to be so enormous, and beyond perception. Where does it end? Is it

conceivable to get as far as possible of the room? Astronomy endeavors to come up with those answers. Like any science, Astronomy makes undeniably more inquiries then it can reply. Be that as it may, that is a piece of what makes it so captivating. As far back as the main explorer pondered what was past the next horizon, people have been attempting to grow their limits. Space science is carrying on that fine convention. It's a really enormous skyline, and perhaps one that doesn't end? Who knows, just space experts of things to come will almost certainly answer that question.

Astronomy Begins At Home

We don't need to run that far with Astronomy, to be really interested. Our very own well-disposed sun has some truly fascinating things going on. Did you know, that the sun moves at a rate of 12 miles for every second? That is 720 miles for each moment or 43,200 miles for every hour. The beneficial thing it has a major gas tank huh? What's more, it's moving towards the group of stars Hercules. Better escape the way Herc! Another fascinating Astronomy goody here. I wager you contemplated the most sizzling thing around. All things considered, way off the mark. The outside of the sun is hot, at around 10,000 degreesfarenheit. In any case, there is something here on earth that is multiple times more sizzling. Care to figure? A few people have even been contacted by it and lived to recount the story.

Helping is 30,000 degreesfarenheit. Cool huh? One all the more startling sun certainty. There are 92 normal components on earth. You recall that intermittent table of components from secondary

school science, those components. All things considered, 66% of those components have been distinguished in the sun. Not certain who checked, however they are there. What's more, researchers trust that the other third are no doubt in the sun also. Difficult to trust our home planet loaded with water could be so firmly identified with that enormous red hot wad of gas. Astronomy turns a quite intriguing story.

Future Worlds

Like those swashbucklers who preceded us and were attracted to wander past their frame of reference. I trust that star gazers of today will be our future limit busters. It might have been some time since individuals have strolled on the moon. Be that as it may, it's only an issue of time. Human instinct just doesn't enable us to agree to what we have. We're continually looking past. Furthermore, cosmology is building that guide, and attempting to help separate those limits of today. It's not just interesting to envision where we will go straightaway, yet fundamental to our survival. We are spending the assets of this planet at a disturbing rate, and sooner before later things will run out. The planet will make due obviously, yet we may not. The time has come to wander out, and discover another planet like earth. For the purpose of revelation, but since we have to. Before long. Ideally, we will touch base there more brilliant, and somewhat more watchful. Meanwhile, Astronomy is clearing the way for our own and future ages to pursue.

Stargazing is not about the collection of huge data and has detailed knowledge about astronomy, anyone who has an interest in the heaven and all the things above us can enjoy the journey of heavens in their leisure time. All you need is binocular, telescope and camera. You might really observe some serious wonders of the sky when you look closely towards it! So, grab yours and start the journey of the heavens.

Do you know, you can actually guess Moon Rise and Set Timing?

2019-02-22T16:57:00.001+05:00

Do you know, you can actually guess Moon Rise and Set Timing?

Just as the Sun rises and sets on the horizon each day, so does the Moon. The time of these events changes depending on the current

phase of the Moon. The Moon can be found as often during the day as often as it can be at night.

When a new moon arrives, the moonrise time is about the same time as sunrise time. Likewise, the moonset time is about the same as sunset time.

• As it waxes to become a crescent moon, then half moon, then the gibbous moon, and onto a full moon, the Moon rises during the day (after sunrise), rising later and later every day, and sets during nighttime, later into the night with every passing night.

• As the full moon approaches, the moonrise and moonset times progress such that the Moon rises at sunset and sets at sunrise.

• As the Moon wanes, becoming a half moon, crescent moon, and returning again to a new moon, the Moon starts to rise during the night (after sunset), and sets during the day.

• Over time, the Moon rises so late that it rises around sunrise while setting at the same time as the sunset. Ultimately, the lunar cycle returns to a new moon all over again.

An estimate of the moonrise and moonset for each phase:

NOTE: Keep in mind that this is just an approximation meant to guide the casual observer, and there's no correction for daylight (or summer) time. The exact local time depends on a number of factors, including time zone, season, the shape of the horizon, atmospheric refraction, among other things.

Earthshine

Earthshine is a dull glow which lights up the unlit part of the Moon because the Sun’s light reflects off the Earth's surface and back onto the Moon.

• Since the light that generates earthshine is reflected twice once off the Earth’s surface and then off the Moon’s surface, this light is much dimmer than the lit portion of the Moon.

• Earthshine is most apparent one to five days before and after a New Moon. The best time of the day to see it is after sunset or before sunrise.

Earthshine is brightest when the lunar crescent is skinniest, in the days just after or before the new Moon.

• It is also sometimes called ashen glow, the old Moon in the new Moon's arms, or the Da Vinci glow, after Leonardo da Vinci, who explained the phenomenon for the first time in recorded history.

• This phenomenon is called planet-shine when it occurs on other planets' moons.

Why the Moon has different phases?

2019-02-22T16:40:00.003+05:00

Why the Moon has different phases?

The cyclical phases of the Moon are actually different angulated views of the Moon created by the relative positions of the Sun, Earth, and Moon.

• At any one point of time, the Moon is half-lit by the Sun (except during lunar eclipses when the Moon is directly behind the Earth with respect to the Sun and is completely shadowed by the Earth).

• However, as the Sun, Earth, and Moon periodically move and orbit through space, the portion we see illuminated on the Moon changes. Since the unlit portion of the Moon remains invisible to the naked eye, we only see the different Moon “shapes.”

• Note that the phases of the Moon are different geometric views of the half-lit Moon from Earth, which are not created by the shadow of the Earth on the Moon.

Moon Phases

The new Moon occurs when the Moon, Earth, and Sun all lie along approximately the same line. Since the Sun is behind the Moon from Earth’s perspective, the side of the Moon that faces Earth is dark.

• At full Moon, the three bodies also lie approximately in a line, but this time, the Moon is on the opposite side of Earth, so the Sun illuminates the whole side facing us.

• At first quarter and last quarter, the Moon lies perpendicular to a line between Earth and the Sun. We see exactly half of the Moon illuminated by the Sun the other half lies on the other side. The "quarter" used to name these phases refers to the respective fraction of an orbit that the Moon has completed since New Moon.

• Crescent refers to phases where the Moon is less than half-illuminated, while gibbous means more than half is illuminated. Waxing means “growing” or expanding in illumination, and wanning means “shrinking” or decreasing in illumination.

Lunar Orbit Cycle

The whole cycle (from new Moon to new Moon) takes about 29.5 days.

Lunar Orbit Cycle

A Lunar Month cycle, the time from full moon to full moon, is 29.53 days. This synodic month is longer than a sidereal month: 27.32 days. This is the time it takes for the Moon to orbit the Earth relative to the view of the stars.

• The discrepancies of the two time periods are due to the fact it takes the Moon 2.21 days to “catch up” because the Earth travels about 45 million miles around the Sun in the time that it takes the Moon to complete one orbit around the Earth.

• If the Earth were not moving, maybe both the time periods would be about the same.

What is the aurora?

2019-02-18T21:25:00.002+05:00

What is the aurora?

Named for the Roman goddess of dawn, the aurora is a mysterious and unpredictable display of light in the night sky. The aurora borealis and aurora australis often called the northern lights and southern lights are common occurrences at high northern and southern latitudes, less frequent at mid-latitudes, and seldom seen near the equator.

While usually a milky greenish color, auroras can also show red, blue, violet, pink, and white. These colors appear in a variety of continuously changing shapes. Sometimes the aurora is as dim and scattered as to be mistaken for clouds or the Milky Way; sometimes it is bright enough to read by.

What does an aurora look like?

Auroras can appear as long, narrow arcs of light, often extending east to west from horizon to horizon. At other times they stretch across the night sky in bands that kink, fold, and swirl, or even ruffle like curtains. They can spread out in multi-colored rays, like vertical shafts of light that stretch far up into space and sometimes they engulf the sky in a thin cloud or veil. What causes the aurora? The typical aurora is caused by collisions between fast-moving electrons from space with the oxygen and nitrogen in Earth’s upper atmosphere.

The electrons which come from the Earth’s magnetosphere, the region of space controlled by Earth’s magnetic field transfer their energy to the oxygen and nitrogen atoms and molecules, making them “excited”. As the gases return to their normal state, they emit photons, small bursts of energy in the form of light. When a large number of electrons come from the magnetosphere to bombard the atmosphere, the oxygen and nitrogen can emit enough light for the eye to detect, giving us beautiful auroral displays. This ghostly light originates at altitudes of 100 to more than 400 km (60 to more than 250 miles)

Why do auroras come in different colors and shapes?

The color of the aurora depends on which gas- nitrogen or oxygen is being excited by the electrons, and on how excited it becomes. The color also depends upon how fast the electrons are moving, or how much energy they have at the time of their collisions. High energy electrons cause oxygen to emit green light (the most familiar color of the aurora), while low energy electrons cause a red light. Nitrogen generally gives off a blue light. The blending of these colors can also lead to purples, pinks, and whites. The oxygen and nitrogen also emit ultraviolet light, which can be detected by special cameras on satellites.

Where can you see an aurora?

Auroras usually occur in ring-shaped areas about 4,000 km in diameter around the magnetic poles of the Earth. These rings are known as auroral ovals. The northern oval traces a path across central Alaska and Canada, Greenland, and northern Scandinavia and Russia. In the southern hemisphere, the auroral oval hovers mostly over the oceans circling Antarctica, but it can occasionally reach the far edges of New Zealand, Chile, and Australia.

The auroral ovals expand and contract with the level of auroral activity, sometimes extending to lower latitudes to cover much of North America or Europe when the space around Earth is most disturbed. The complete auroral ovals in the north and south are nearly mirrored reflections of each other, or conjugate. But it was not until the space age when satellites could gather images the largescale auroras around both poles at the same time.

How is the aurora-related to the Sun?

Auroras are a sign that Sun and Earth are connected by more than sunlight. They indicate that something electric is happening in space. The Sun provides the energy for the Aurora, but particles in the aurora come from Earth’s own neighborhood in space. The Sun’s energy is carried toward the Earth in the solar wind, a stream of electrically charged particles (mostly protons and electrons) flowing out from the Sun in all directions. As these particles approach Earth, they interact with our planet’s magnetic field. This field deflects most of the particles, creating a huge cavity in the solar wind–the magnetosphere. This region stretches about 60,000 km toward the Sun and several hundred thousand kilometers in a long tail on the night side, away from the Sun.

Variations in the properties of the solar wind control the amount of energy that can leak into the magnetosphere. Here the energy is converted into electric currents and electromagnetic energy and temporarily stored in the magnetosphere, especially in its tail. When this influx of energy is relatively large, the magnetosphere loses its equilibrium or balance. To become stable again, the excess energy is released suddenly, with much of the energy going into the acceleration of electrons. The aurora primarily occurs where the magnetic field guides the electrons from the tail of the magnetosphere into the atmosphere where they produce the aurora. Because the tail is on the night side of the Earth (away from the Sun), the more intense, dynamic and beautiful auroras occur near midnight.

JOURNEY TO ASTRONOMY

2019-02-18T03:10:00.002+05:00

JOURNEY TO ASTRONOMY

Astronomy is the study of stars, planets, and space. As you study astronomy, you will learn about yourself.

Astronomy tells you:

• Where are We?

• When is Now?

• What are We?

WHERE ARE WE?

Knowledge of Earth's location in the Universe has been shaped by 400 years of telescopic observations and has expanded radically in the last century. What we know right now is that we live on Earth which is a planet.

*Earth: Home Planet

*The orbit of Moon: 768,210 km. The average diameter of the

orbit of the Moon relative to the Earth.

*Earth’s orbit: 299.2 million km. The average diameter of the orbit

of the Earth relative to the Sun. Encompasses the Sun, Mercury,

and Venus.

*Inner Solar System: Encompasses the Sun, the inner planets

(Mercury, Venus, Earth, Mars) and the asteroid belt.

*Outer Solar System: Includes the outer planets (Jupiter, Saturn,

Uranus, Neptune).

*Kuiper belt: Belt of icy objects surrounding the outer Solar

System. Encompasses the dwarf planets

*Oort cloud: Spherical shell of over a trillion comets.

*Local Interstellar cloud: Interstellar cloud of gas through which

the Sun and a number of other stars are currently traveling.

*Milky Way galaxy: Our home galaxy, composed of 200 billion to

400 billion stars and filled with the interstellar medium.

*Local group: Group of at least 47 galaxies of which the Milky

Way is a part. Dominated by Andromeda (the largest), the Milky

Way and Triangulum; the remainders are dwarf galaxies.

*Virgo supercluster: It comprises roughly 100 galaxy groups and

clusters, centered on the Virgo Cluster. The Local Group is

located on the outer edge of the Virgo Supercluster.

*Observable Universe: More than 100 billion galaxies, arranged in

millions of superclusters, and voids creating a foam-like

superstructure.

*Universe: Minimum Beyond the observable universe lie the

unobservable regions from which no light has reached the Earth

yet. No information is available, as light is the fastest traveling

medium of information. The Universe is likely to contain more

galaxies in the same foamlike superstructure.

WHEN IS NOW?

Now that you have an idea where you are in space, you need to know where you are in time. The stars shone for billions of years before the first human looked up and wondered what they were.

Imagine beginning is BIG BANG and replaying the entire history of the universe till TODAY. Observations tell astronomers that the big bang filled the entire universe with hot, glowing gas, but as the gas cooled and dimmed, the universe went dark.

There was no light for the next 400 million years until gravity was able to pull some of the gas together to form the first stars. Galaxies formed in large numbers. Our home galaxy would be one of those taking shape.

By the time universe is full of galaxies, but the sun and Earth have not formed yet.4.6 billion years ago, about 9 billion years after the big bang, marks the formation of the sun and planets of our solar system

About 3.4 billion years ago, to mark the earliest firm evidence for life on Earth microscopic creatures in the oceans and the emergence of life on land only 0.4 billion (400 million) years ago.

Dinosaurs go extinct 65 million years ago.

What about people? 4 million years from TODAY.

Civilization, the building of cities, began about 10,000 years ago.

Compare the history of human civilization with the history of the universe. Every war you have ever heard of, every person whose name is recorded, every structure ever built from Stonehenge to the building you are in right now shows that Humanity is very new to the universe. Our civilization on Earth has existed for only a flicker of an eye-blink in the history of the universe. Only in the last hundred years or so have astronomers begun to understand where we are in space and in time.

WHAT ARE WE?

Astronomy is important to you because it will tell you what you are. Notice that the question is not “Who are we?” As you study astronomy, you will learn how you fit into the history of the universe. You will learn that the atoms in your body had their birth in the big bang when the universe began. Those atoms have been cooked and remade inside generations of stars, and now, after billions of years, they are inside you. Where will they be in another billion years? This is a story everyone should know, and astronomy is the only course on campus that can tell you that story.

Binoculars For Astronomy Lovers

When purchasing binoculars for Astronomy, one of the fundamental goals is the light assembling ability of the binoculars you are hoping to purchase and subsequently, the span of the target focal point is critical.

How to begin

Before you begin to look at the scope of binoculars for space science that is as of now available you have to consider the separation you are hoping to cover and what dimension of detail you want to see. On the off chance that you can envision that a telescope can furnish you with an altogether bigger aperture (target focal point) and a wide scope of amplification capacities it's reasonable that for survey over longer separations, and to see the better subtleties, a telescope is regularly a superior alternative. Anyway, that said binoculars can demonstrate helpful, notwithstanding for the genuine space expert, and are a modest method to begin.

The genuine motive of utilizing binoculars for Astronomy is the insignificant setup time, the moderately minimal effort, convenient and are an inexpensive way to get started.

Makers, by and large, demonstrate regardless of whether their binoculars are reasonable binoculars for Astronomy however as a general guide you need to search for monster binoculars or binoculars with a target focal point that is 50mm or more noteworthy. 10x50's are frequently a well-known decision for stargazing as they are sensibly agreeable to hold yet sufficiently incredible for the fundamental space experts needs.

Binoculars for Astronomy, all you need is:

Fully multi-covered focal points are an absolute necessity

Waterproof binoculars are commonly best in the event that you need to avoid hazing and see in every single climate condition.

Always check a binoculars appropriateness for Astronomy.

Remember the more dominant the better and on the off chance that you need an execution like a little telescope purchase a binocular with the biggest conceivable target focal point.

For bigger binoculars ensure you check tripod/mounting requirements.
Quality optics are vital and no more so than for Astronomy. On the off chance that you can bear the cost of fantastic binoculars, they are well worth paying for.

Here are some best binoculars which you can purchase for your astro-journey.

Have you ever wonder how seasons change?

2019-02-16T20:43:00.000+05:00

Have you ever wonder how seasons change?

We are too busy in our daily routine that we never wonder how seasons get change. Here is a short explanation of how earthlings experience the season change throughout the year.

We can’t really feel that the Earth is orbiting the Sun (even though the Earth is traveling 30 km/s), and these days not many people take notice of the Earth’s orbital position. We primarily notice the passing of a year by the cycle of the seasons.

So what is the cause of the seasons?

Clearly, the seasons have something to do with the Earth’s orbit around the Sun. Yet many people are confused about why the Earth has seasons.

Why do seasons occur?

“The seasons are caused by the changing distance between the Earth and the Sun, and it is warmer in summer because the Earth is closer to the Sun at summer time.”

This is a very common response and it is true that the Earth-Sun distance does change. As we just saw, the Earth’s distance from the Sun varies by about 3% during its orbit. So could summer occur when the Earth is closest to the Sun?

NO!

Earth is farthest from the sun on its orbit when it is summer in the Northern Hemisphere.

The Earth is closest to the Sun at its Perihelion about 2 weeks after the December Solstice and farthest from the Sun at its Aphelion about 2 weeks after the June Solstice.

Another, problem with this idea is that when it’s summer in the northern hemisphere, its winter in the southern hemisphere, and vice versa. So if this were the correct answer, it would be the same season in both hemispheres at the same time which is not the case.

So how we experience a change in seasons?

The direction of the rotational axis stays (nearly) fixed in space while the Earth orbits the Sun and the hemisphere that seems to “lean into” the Sun experiences summer, while the hemisphere that “leans away” from the Sun experiences winter.

Thus the tilt of the Earth’s rotation axis naturally explains why the seasons are opposite in the northern and southern hemispheres

In December, when the southern hemisphere is tilted towards the Sun, the southern part of the Earth receives more sunlight and experiences long summer days. At the same time, the northern hemisphere is tilted away from the Sun and receives less sunlight, experiencing short winter days.

What if you are living at the Equator?

If you live near the Equator, there is not much difference between the seasons all year round. During spring and autumn, the two hemispheres receive approximately equal amounts of sunlight.

What if you are living at the North or South pole?

If you are at the North or South Pole, then also experience two very long seasons: in summer, the North Pole is leaning towards the Sun and there is “daylight” for nearly six months. In winter, the North Pole is leaning away from the Sun and it is “nighttime” for nearly six months.

In most cultures, including all western countries, the year is commonly divided into four seasons: Spring, Summer, Fall or Autumn, Winter.
Since the year has 12 months, each season lasts about three months.

To keep your eyes a the sky you need some gadgets, which you can buy from here. You can start with binoculars which are cheap and handy.

Are you interested in stargazing?

2019-02-15T15:14:00.000+05:00

Are you interested in stargazing?

If you are keenly interested in stargazing or have some previous knowledge about astronomy, so let me tell you about a myth, on which we have believed since our childhood.

Do you really think that the sun rises from the east and set towards the west?

You might have some serious misunderstanding regarding heavenly bodies. Since we all had been told this, but this is not actually the case. You haven’t focused yet because of your daily busy lives. If you observe thy sky throughout the year, you will find some interesting facts about it.

First of all, the sun not rises exactly from the east neither set in the west.

Get up in the morning and take observation of the sun, mark the date and position of the sun.

Suppose you start observing this from December, take a compass and turn towards the sunrise, you will find that the position of the sunrise is not actually from the east. It is nearly from the southeast and the setting position of the sun is southwest, day by day you will notice this shift towards south east/west till 21st December. Which is the shortest day of the year in the northern hemisphere, it is called winter solstice.

Mark the date and position and now observe this after 3 or 4 weeks, you will find the change in position of the sunrise which is shifting day by day towards east and change in the setting position too, till the 21st March. Okay, this is the day on which the sun actually “rises from the east and sets in the west”, and the day is called “vernal equinox”. Mark this day too!

Can you guess what happens after this?

You might have guessed right! after 21st March the sun starts rising nearly from the northeast and set nearly towards the northwest, this shift continues till 21st June which is the longest day of the year in the northern hemisphere and it is called summer solstice. On this day you will notice the sun is shifted towards the northeast, day by day. And then again from 21st June to 21st September, the sun appears to shift from northeast/northwest, towards exactly east/west on 21st September. And again on this day, the “sun rises from east and sets in the west”, and the day is called “autumnal equinox”

(1st December to 21st December)

Still, have some confusion so look at this image. In this, I have set my position and took observations daily at the same time but on different days (from 1st December to 21st December). You can identify clearly this shift and you can do this observation by yourself, collect you astrography and tell it to others, your friends will really impress from you!
