THE SAUROPODOMORPHA ("lizard-feet forms.")were herbivorous, usually quadrupedal (four-footed)dinosaurs. A clade within Saurischia, they were characterized by small heads, bulky bodies, andlong necks and tails. Sauropodomorphs haveoften been split into two groups: prosauropodsand sauropods. Prosauropods lived from LateTriassic to Early Jurassic times (225-180 million years ago) andincluded

AN ENORMOUSLY SUCCESSFUL SUBGROUP of the Saurischia, the bipedal (two-footed) theropods (“beast feet”) emerged 230 million years ago in Late Triassic times; the oldest knownExample comes from South America.Fossil Skeleton of ArchaeopteryxTheropods spanned the age ofmost dinosaurs (230-65 million years ago) and beyond, and includedmost of the known predatory dinosaurs.

The Dinosaurs (Important Facts) {Part-14}

THE DINOSAURS WERE A LARGE GROUP of reptiles that were the dominant land vertebrates (animals with backbones) for most of the Mesozoic era (245-65 million years ago). Dinosaurs They appeared some 230 million years ago and were distinguished from other scaly, egg-laying reptiles by an important feature dinosaurs had an erect limb stance. This enabled them to keep their bodies well above the

Message for Upcoming World

Arecibo Message was written by Dr. Frank Drake and Carl Sagan which was blasted towards the Arecibo Message M13 star cluster in 1974. It's composed of semi prime no. of binary digits conveying some info about us and it should reach the center of M13 cluster in about 25,000 years at which point something intelligent lives there and detects it. They can respond and there response will

Warmhole -Space Talks#7

2019-03-02T15:56:00.000+05:30

A highly speculative idea of modern astrophysics, warmholes are theoretical possibilities allowed within the mathematical framework of Einstein's general theory of relativity. A warmhole is a short-lived portal, lasting only a brief moment, that joints two black holes in different locations. Warmhole Warmholes could connect two points in the present-day universe or, perhaps, in

The Zodiac -Space Talks#6

2019-02-26T18:29:00.000+05:30

The Zodiac is a band of constellations that extends roughly nine degrees on each side of the ecliptic, the sun's apparent yearly path through our sky. Constellations of the Zodiac Ancient Greek astronomers divided the zodiac into 12 parts. Over time, Earth's slight rotational wobble has shifted the ecliptic by more than 30 degrees against the backdrop of stars. The 18-degree-wide now also

Constellations -Space Talks#5

Stars seem to move across the sky through the night, but that movement is due to Earth's rotation. As Earth spins on its axis, objects appear to rise in the east and set in the west. In the Northern Hemisphere, some stars never appear to set, called Circumpolar Stars, they circle at a point projected in the sky above the Northern Pole near Polaris, the Pole Star. A corresponding situation

Discovery of Big Bang -Space Talks# 4

2017-09-21T13:24:00.000+05:30

The first scientific evidence for the Big Bang was found in 1929, when astronomers discovered that light from distant galaxies is rendered. This color change happens when objects are moving away from us, making light waves stretch out and change color. The more distant the galaxies are, the faster they rushing away. This shows that the whole Universe is expanding. No charge in starlight

Star death- Space Talks# 3

2017-09-20T06:50:00.002+05:30

All stars eventually run out of fuel and die. Most fade away quietly, but the most massive stars self-destruct in a huge explosion that can outshine an entire galaxy. Like Earth, stars generate the force of gravity which squeezes their hot core. The more matter a star has, the greater the force of gravity and the hotter and denser the core becomes. The way a star dies depends on how powerfully

Seeing the invisible- Space Talks# 2

Professional astronomers don't just use visible light to see the night sky. Their telescopes can also create images from wavelengths of light that our eyes cannot see, such as X-rays, radio waves and infrared rays. The images below all show kepler's Supernova - the wreckage left by a giant star that exploded in 1604. X-ray image:- X-ray image of Kepler's

Astronauts must adapt to a zero-gravity environment when weightlessly can be fun, it can also cause medical problems. Space stations are cramped places with few luxuries. Astronauts eat ready-made meals that are either freeze-dried or served in pouches. All water is recycled, including the water vapour from human breath. Astronauts clean themselves with special shampoos and soaps that don't need

Artist Thierry Cohen mocked up what big cities would look like if all their lights were off and the sky above them could be seen fully, New York, Hong Kong, Shanghai, Tokyo, Los Angeles. New York Los Angeles Tokyo Shanghai It's beautiful and rare. In the 1990's during a black out in the city of Los Angeles, a number of residences actually called the Police, they were

Preparing Nanoparticles by Emulsification Diffusion Method

In this method, water-in-oil (w/o) emulsion is prepared by emulsifying the chitosan solution in the oil phase. Aqueous droplets are stabilized using a suitable surfactant, the stable emulsion is cross-linked by appropriate cross-linking agent such as glutaraldehyde to harden the droplets, and the particles are filtered and

Welcome to the Series of Dazzling thing in the Universe:- (Part -3) Before making their final death plunge into the Black Hole. In the disc, debris spins at unfathomable speeds, pulled around by a Black Hole billions of times more massive than our Sun. Friction in the accretion disc generates heat on a level difficult to fully appreciate. Just as hot things glow, the disc does too. So,

Preparation of nanoparticles by Ionic gelation

2017-08-27T12:17:00.000+05:30

Nanoparticles are materials ranging from 1-1000 nm dimension. Size range of 1-500 nm is generally considered fine nano range while above 500 nm are considered coarse nanoparticles. (Adlin et al., 2009). Their unique physico-chemical characteristics like ultra-small size, large surface area to mass ratio and high reactivity differentiates them from
