Mars has just offered scientists another tantalizing clue in one of the greatest mysteries in planetary science:

Did life ever exist on the Red Planet?

NASA’s Curiosity rover has uncovered the most diverse collection of organic molecules ever found on Mars. Even more exciting, seven of these carbon-rich compounds had never before been detected on the Martian surface.

That sounds dramatic — and it is.

But let’s be clear right from the start: this is not proof of life on Mars.

Organic molecules are not the same thing as living organisms. They are carbon-based chemical ingredients that life uses, but they can also form through non-biological processes. They can be created by geology, delivered by meteorites, or shaped by chemistry that has nothing to do with biology.

Still, this discovery is a big one.

Because what Curiosity has found tells us that ancient Mars may have preserved complex organic chemistry for billions of years — despite radiation, freezing temperatures, and the harsh surface conditions we see there today.

In other words, Mars may be a cold desert now, but its rocks are still holding onto whispers from a much warmer, wetter past.

A Tiny Sample With a Huge Story

The discovery comes from a rock sample Curiosity drilled in 2020 at a site nicknamed Mary Anning, after the famous 19th-century fossil hunter who helped transform our understanding of ancient life on Earth.

Curiosity collected the sample in Gale Crater, where the rover has been exploring since 2012. Rising from the center of that crater is Mount Sharp, a layered mountain that acts like a history book of Martian climate and geology.

For years, Curiosity has been climbing that mountain, heading toward clay-rich layers first spotted by orbiting spacecraft. That was a major target because clay minerals are especially good at preserving organic material.

And that is exactly where things get interesting.

The region Curiosity explored contains evidence of ancient lakebeds and places where water once flowed into those lakes. We are talking about a Mars that once had standing water, muddy sediments, and repeated wet-dry cycles.

That is not the Mars of today.

That is a Mars that may once have had environments where life — if it ever arose there — could have found a place to survive.

Mars Was Not Just Habitable — It May Have Been Surprisingly Habitable

One of the most striking ideas from this discovery is not simply that Mars was once potentially habitable.

It is how good some of those environments may have been.

Curiosity has already shown that Gale Crater once had water, the right minerals, and energy sources that could have supported microbial life. Now we can add something else to that picture: a rich and diverse set of preserved organic molecules.

That does not mean microbes were crawling around ancient Mars.

But it does strengthen the case that Mars had some of the right ingredients and conditions at the right time.

Think of it this way: Curiosity is not finding a fossil. It is finding the chemical scenery where a fossil-worthy story might have once unfolded.

A First-of-Its-Kind Chemistry Experiment on Mars

One of the most remarkable parts of this discovery is how Curiosity made it happen.

This was not simply a rover sniffing the air or scraping a rock.

Curiosity performed a sophisticated chemistry experiment on another world.

After drilling the rock, the rover pulverized the sample and delivered it into SAM, short for Sample Analysis at Mars — a miniaturized laboratory tucked inside Curiosity’s belly.

SAM can heat samples and analyze the gases released from them. But for this experiment, scientists used something even more special: a wet chemistry technique.

The powdered Martian rock was mixed with a chemical solution called TMAH, which helps break apart larger, harder-to-detect molecules into smaller fragments that Curiosity’s instruments can identify.

That is astonishing when you stop to think about it.

A robot on Mars drilled into an ancient lakebed, scooped powdered rock into its onboard lab, mixed it with a chemical reagent, heated it, and identified hidden organic compounds that had been locked away for billions of years.

This is not science fiction.

This is planetary exploration in the 21st century.

What Did Curiosity Find?

The experiment revealed 21 carbon-containing molecules, including seven never before seen on Mars.

Among the most intriguing was a type of nitrogen-bearing ring structure known as a nitrogen heterocycle.

That may sound technical, but here is why it matters: nitrogen-containing rings are important in the chemistry of life on Earth. Similar structures are part of the molecular family tree connected to RNA and DNA.

Again, Curiosity did not find DNA.

It did not find cells.

It did not find evidence that Martian life existed.

But it did find chemistry that shows ancient Mars was capable of preserving more complex organic material than scientists had previously confirmed.

Another molecule detected was benzothiophene, a compound containing both carbon and sulfur. Similar organic material is found in meteorites, raising another fascinating possibility: some of Mars’ organic ingredients may have been delivered from space by impacts, just as similar materials may have rained down on early Earth.

That is a beautiful cosmic connection.

The same solar system debris that helped seed Earth with organic ingredients may also have sprinkled Mars with some of the same raw materials.

A Martian Mystery With an Earthly Test

To make sure Curiosity’s chemistry was telling the right story, researchers also tested the method here on Earth.

They used the famous Murchison meteorite, which fell in Australia in 1969 and is known to contain ancient organic compounds. When scientists treated that meteorite sample with the same type of chemistry Curiosity used on Mars, it broke larger molecules into smaller pieces similar to those seen in the Mary Anning sample.

That gives scientists more confidence that Curiosity may be detecting fragments of larger, more complex organic material preserved in Martian rock.

And that is the key point.

Curiosity may only be seeing the tip of a much larger chemical iceberg.

Why This Discovery Matters So Much

For me, this is one of those Mars discoveries that does not arrive with little green aliens or dramatic headlines.

It arrives as something quieter — and maybe even more powerful.

A powdered rock sample.

A chemistry experiment.

A handful of molecules.

And a message from 3.5 billion years ago.

These molecules suggest that ancient Martian rocks can preserve organic chemistry across immense stretches of time. That is vital because if Mars ever did host life, the evidence may still be hidden in its ancient sediments.

But there is a catch.

Curiosity is brilliant, but it is still a rover with a tiny lab. To truly answer the question of life on Mars, scientists need to bring carefully chosen rock samples back to Earth, where powerful laboratory instruments can examine them in far greater detail.

That is why Mars sample return remains such a big dream for planetary scientists.

The Perseverance rover is already collecting promising samples in Jezero Crater, another ancient lake environment on Mars. Some rocks there even show unusual markings that scientists are studying as possible signs of ancient chemical activity.

But until those samples are brought home, the deepest questions remain just out of reach.

Curiosity Is Still Living Up to Its Name

Curiosity landed on Mars in 2012.

More than a decade later, it is still exploring, still drilling, still climbing, and still changing our understanding of the Red Planet.

That alone is remarkable.

This latest discovery also points the way toward future missions. The European Space Agency’s upcoming Rosalind Franklin rover is expected to carry its own tools for studying organic chemistry on Mars. NASA’s Dragonfly mission to Saturn’s moon Titan will also use chemistry experiments to investigate one of the most fascinating worlds in the solar system.

In many ways, Curiosity has helped write the playbook.

It has shown that a rover can do real chemistry on another planet — and that Mars still has secrets worth digging for.

The Big Question Remains

So, did Mars ever have life?

We still do not know.

But we now know that ancient Mars had water.

It had clay-rich environments.

It had lakebeds.

It had chemistry.

And it preserved organic molecules for billions of years.

That is enough to keep the mystery alive.

The Red Planet is not giving up its secrets easily. But with every drilled rock and every new molecule, Curiosity is helping us piece together a story that began when both Earth and Mars were young worlds under the same ancient Sun.

Maybe Mars was always lifeless.

Maybe it was briefly alive.

Or maybe, somewhere in its rocks, the answer is still waiting.

For now, one thing is certain:

Mars just became even more interesting.

On the night of Saturday, April 25, 2026, skywatchers across parts of the eastern United States, Central America, and northeastern South America will have a chance to see the waxing gibbous Moon pass directly in front of Regulus, the brightest star in the constellation Leo, the Lion. At the time of the event, the Moon will be about 71% illuminated. 

Astronomers call this an occultation. That is simply when one object in the sky moves in front of another and temporarily hides it from view. In this case, the Moon will briefly blot out Regulus, one of the sky’s standout stars. 

And what makes this especially fun is that Regulus is no dim speck. It is a 1st-magnitude star, bright enough to stand out even in moonlit skies, and it lies about 78 light-years away from Earth. The light you’ll see left that star decades ago, only to be cut off in an instant by our much closer cosmic neighbor. 

What you’ll see

If you are in the right place with clear skies, the show can be surprisingly dramatic.

As the Moon moves eastward in its orbit, its darker edge will creep closer and closer to Regulus. Then, in a blink, the star will vanish. Not fade. Not slowly dim. Just disappear. That sudden “switching off” happens because stars are so far away they appear as pinpoints of light, even through a telescope. 

Later, Regulus will reappear from the Moon’s bright edge. That part can be trickier to catch because of the Moon’s glare, but it is every bit as fascinating. Occultations are really two events in one: the disappearance and the reappearance. 

Why this is such a neat thing to watch

For me, events like this are a wonderful reminder that the sky is alive with motion.

Night after night, the Moon is constantly shifting its position against the background stars. Every now and then, it lines up perfectly with one of the brighter stars along its path. Only four 1st-magnitude stars lie close enough to the Moon’s path to be occulted this way: Regulus, Spica, Antares, and Aldebaran. 

This event also reveals something important about the Moon itself. Because the Moon does not have a thick atmosphere, Regulus won’t slowly fade away as it disappears. It will cut off sharply. If the Moon had a dense atmosphere, the star’s light would blur and dim first. That crisp vanishing act is one of the clearest demonstrations that the Moon is essentially airless. 

Can beginners see it?

Yes — especially if you have binoculars or a small telescope.

Along the Eastern Seaboard, some observers may be able to spot Regulus with the unaided eye before it disappears because the sky will be darker there by event time. Farther west, the occultation happens in brighter twilight, near sunset, or even in daylight, so binoculars or a telescope become much more important. Reappearance is usually harder to see without optics because it happens at the Moon’s bright limb. 

A telescope is the best tool here because magnification helps cut through the Moon’s glare and makes it much easier to see the star right up to the moment it disappears — and again when it pops back into view. 

How to prepare

My advice is simple:

Get outside early and give yourself time to get oriented. Find the Moon first, then look for Regulus nearby in Leo. Keep your attention on the Moon’s darker edge, because that is where the star will vanish first. If you have binoculars, use them. If you have a small telescope, even better. 

And don’t be discouraged if the event happens in a bright sky from your location. Even daytime or twilight occultations can sometimes be seen with optical aid. 

When Will Regulus Disappear? City-by-City Viewing Times

Below is a blog-friendly city list for the Regulus lunar occultation on Saturday evening, April 25, 2026 in North America. The IOTA master table is in Universal Time, but these are converted to local clock time where listed. Sky & Telescope notes that the occultation is visible from the eastern U.S., Central America, and parts of northeastern South America, with the IOTA table using UT and requiring time-zone conversion.

What the times mean:
Start = Regulus disappears behind the Moon’s dark edge.
End = Regulus reappears from behind the bright edge of the Moon.
An asterisk means the disappearance happens in bright twilight or around sunset, so binoculars or a small telescope will help. Space.com’s published table provides the 15-city Eastern Time subset below and notes the full IOTA prediction set includes 660 locations.

Important near-miss note:
New York City does not get a full occultation; Regulus passes extremely close to the Moon around 9:04 p.m. EDT, while Boston sees a wider near miss. The northern boundary running roughly from Michigan through Mississauga, western New York, northeast Pennsylvania, and central/western New Jersey.

Safety note for daylight/twilight locations:
If the Sun is still up, be extremely careful with binoculars or telescopes. Never sweep near the Sun; use the Moon as your target and keep the Sun physically blocked from view. Warning: even a momentary telescopic glance at the Sun can cause permanent eye damage.

A rare chance worth taking

These lunar meetings with Regulus come in cycles. The current occultation season for Regulus began in July 2025 and wraps up in December 2026. After that, the next time the Moon will cover Regulus for observers in the United States will not be until June 27, 2036. 

So this is not the kind of sky event you’ll want to casually put off for “next time.”

Final thoughts

There is something wonderfully humbling about watching the Moon, a world just next door on the cosmic scale, briefly hide the light of a distant star that has been shining toward us for 78 years.

It is quiet. It is simple. And yet it puts the clockwork beauty of the universe on full display.

So if skies are clear where you live this Saturday night, step outside and look up.

You might just catch the heart of the Lion disappear before your eyes.

If you’ve been following the rumor mill today, the folks over at MacRumors just dropped a bombshell regarding Apple’s possible “four-part plan” for the iPhone camera. 

If true, Apple is playing the long game, rolling out these features over the next several years. Let’s look at the roadmap for how the iPhone could evolve into a legitimate deep-space contender.

Phase 1: Control the Light (The iPhone 18 Pro)

Feature: Variable Aperture

The first stop on this multi-year journey starts with the iPhone 18 Pro (likely arriving this September). Since the iPhone 14 Pro, we’ve been stuck with a fixed ƒ/1.78 aperture.

Phase 2: The “Ultra-Large” Hardware Shift

• The Upgrade: Apple is reportedly moving to a physical variable aperture.
  
• This is a huge win for optical perfection. While we want that wide opening to grab every photon possible, being able to “stop down” slightly will help us fight coma—that annoying distortion where stars at the edge of your frame look like tiny seagulls. Expect sharper, cleaner stars from corner to corner starting this year.

Feature: 1/1.12-inch Main Sensor

This one is “in testing” for the years following the iPhone 18. While the 1/1.12-inch label is an industry term (referring to old video tube sizes), the physical diagonal is roughly 14.5mm. In the world of phones, that is massive.

• Why it matters: This is the heavyweight champion of the roadmap. A larger sensor means larger pixels, and larger pixels mean a better Signal-to-Noise Ratio.
  
• The Result: Think velvety black skies instead of that grainy, purple-ish digital noise. This will be the single biggest leap for handheld Milky Way shots.

Phase 3: The Deep Space Zoom

Feature: 200MP Periscope Telephoto Lens

Further down the timeline, Apple is looking to shatter the resolution ceiling with a 200-megapixel telephoto monster.

• The Tech: At night, you won’t actually shoot at 200MP. Instead, the phone will use “pixel binning” to combine groups of pixels into high-sensitivity “super-pixels.”
  
• The Result: This is for the lunar photographers. With this much data, you’ll be able to crop into the craters of the Moon or the glow of Jupiter with unprecedented detail. It turns your phone into a legitimate “pocket telescope.”

Phase 4: Rock-Solid Landscapes

Feature: Enhanced OIS for Ultra-Wide

The Ultra-Wide lens is our go-to for those epic “tent under the stars” shots, but it’s historically been the weakest lens in the kit.

• The Upgrade: Apple plans to bring professional-grade Optical Image Stabilization (OIS) specifically to the Ultra-Wide.
• The Result: This is your “I forgot my tripod” insurance. It allows for longer “Night Mode” exposures while handheld, keeping the stars as sharp pinpoints rather than blurry streaks.

The Big Picture

The takeaway? If these rumours are true, we would be entering a multi-year era of mobile astrophotography. While the Variable Aperture on the iPhone 18 Pro kicks things off by giving us better optical control, the real “Holy Grail” is that 1/1.12-inch sensor coming down the pike. This would mean hardware is finally catching up to the software, and for us “Night Sky” types, the future is looking brighter (and much more detailed) than ever.

Which of these roadmap stops are you most willing to wait for? Let me know in the comments!

What does it take to see some of the most breathtaking sights in the universe—all in a single night?

During Global Astronomy Month, I teamed up with Astronomers Without Borders to host a special livestream exploring the greatest hits of the Messier Marathon—a legendary observing challenge featuring 110 deep-sky objects discovered by 18th-century astronomer Charles Messier.

Using the powerful and beginner-friendly Dwarf 3 Smart Telescope from Dwarflab, we journeyed across the cosmos in real time—visiting glowing stellar nurseries, ancient star clusters, and distant galaxies millions of light-years away.

From the stunning clouds of the Orion Nebula to the vast island universe of the Bode and Cigar galaxies, this session was designed to show just how accessible and awe-inspiring stargazing can be—no matter your experience level.

Whether you joined us live or are watching the replay, this guided tour offers a front-row seat to the wonders of the night sky—and a reminder that the universe truly belongs to all of us.

Note: During this livestream, we used the Dwarf 3 smart telescope from Dwarflab to capture many of the images you saw in real time. If you’re curious to learn more about the Dwarf 3—or are thinking about getting started with a smart telescope of your own—you can find more information here .

For most of us, the idea sounds a little wild.

A crewed spacecraft on its way around the Moon… spotted not by a giant observatory, but by everyday skywatchers standing in their backyard with a pair of binoculars.

And yet, for a brief slice of NASA’s upcoming Artemis II mission, that may actually be possible. According to a visibility analysis published by Spaceweather.com, the best chance comes during Orion’s closest pass to Earth on April 2, when the capsule could briefly brighten to around magnitude 7 to 9 — bright enough, at least in theory, for binoculars. Spaceweather’s analysis says that pass is expected around 23:00 to 23:30 UTC, and warns that Orion will also be moving several degrees per minute, which is the big catch.

That means this is not going to be like finding Jupiter, the Pleiades, or a bright comet and then leisurely admiring it. If Orion does pop into binocular range, it will likely be a fast-moving target during a short-lived window. In other words, this is a challenge — but it is also one of the coolest observing challenges backyard skywatchers have had in a very long time.

Why binoculars might actually work

Spaceweather.com’s analysis is based on JPL Horizons ephemeris data, Ted Molczan’s brightness estimates, and the mission timeline. Their day-by-day breakdown says Orion’s Day 1 close approach is the standout moment for small optical aid. Earlier in the mission, while Orion is still in its initial elliptical Earth orbits, the spacecraft is estimated at about magnitude 10.7 to 12.7, which is telescope territory. But during the close perigee pass, it may brighten dramatically into the magnitude 7 to 9 range. That is the range where many observers under decent skies can at least attempt a binocular sighting.

There is one important caution here: Spaceweather notes the estimates carry about ±2 magnitudes of uncertainty. So Orion could turn out a little brighter than expected — or disappointingly fainter. That uncertainty matters a lot when you are pushing the limits of binocular viewing.

Can You See NASA’s Artemis II Orion Capsule With a Backyard Telescope? NASA’s Artemis II Orion capsule may be visible in backyard telescopes during key parts of its Moon mission. Here’s when skywatchers should look.

Why it still won’t be easy

At closest approach, Orion is expected to be moving very quickly against the background stars — fast enough that Spaceweather describes it as moving several degrees per minute. That is a huge clue for beginners: even if the capsule is technically bright enough, keeping it inside a binocular field of view may be the real challenge.

This is also why casual sky apps and ordinary satellite trackers may not be enough. For Orion, Spaceweather specifically points observers to JPL Horizons, where you can generate topocentric coordinates for your own location. That means you can get the object’s changing altitude and azimuth — in plain English, exactly where to point from your own backyard. Spaceweather’s Horizons guide says you can search for “Artemis II” or object number -1024, then set your observing location and generate coordinates at short time intervals such as 5 or 10 minutes for the close passes.

The mission timing matters too

NASA says Artemis II is the first crewed flight of Orion around the Moon, and the mission is expected to last about 10 days, with Orion spending the first one to two days in high Earth orbit before heading outward on its translunar injection burn. That early mission phase is exactly why the April 2 viewing opportunity exists: Orion is still relatively close to Earth before it heads much deeper into space. (NASA)

The current launch opportunities  begin on April 1, 2026 at 22:24 UTC, with later backup opportunities on April 2–5. That matters because any practical observing plan depends on the actual launch date. If the launch slips, the binocular window will shift too.

So… can beginners really try this?

I would frame this as a fun challenge, not a guaranteed binocular “show.” The likely sweet spot is for observers who already know how to sweep the sky steadily, use a tripod or braced position, and follow printed or digital coordinates in real time. Absolute beginners can still try, but the key is to think of this as an experiment: if you catch Orion, fantastic. If not, you still took part in one of the most unusual observing opportunities of the Artemis era.

A practical beginner’s guide to trying with binoculars

1) Aim for the best window

Your main binocular shot is the April 2 close pass, around 23:00–23:30 UTC, because that is when Orion is expected to brighten the most. If you are converting that to local time, be careful — use your local time zone correctly on the day of the event. The exact timing may shift if launch timing changes.

2) Use the right binoculars

A basic pair of 7×50 or 10×50 binoculars gives you a reasonable balance of brightness and field of view. In a challenge like this, a wider field is your friend because Orion may be moving quickly. Giant high-power binoculars can actually make the hunt harder unless they are mounted. This advice is an observing inference based on the speed issue and on Orion’s brief binocular-bright window.

3) Stabilize yourself

Do not try this freehand if you can avoid it. Lean against a deck rail, fence, car roof, or tripod-mounted binocular support. Even sitting in a lawn chair and bracing your elbows can help. When the target is faint and moving, steadiness matters.

4) Get exact coordinates from JPL Horizons

This is the big one. Spaceweather’s observing guide says to use JPL Horizons, enter Artemis II or -1024, set your location, and request Azimuth/Elevation plus Right Ascension/Declination. For the close pass, use short time steps like 5 minutes or 10 minutes. That will give you a moving breadcrumb trail to follow.

5) Practice before the big night

The night before, practice sweeping to a known bright satellite pass or a planet near the same part of the sky. This is less about seeing Orion and more about training your body and binoculars to move smoothly.

6) Start early

Do not wait until the exact minute of closest pass. Be outside and ready 15 to 20 minutes ahead of time, with your coordinates already loaded or printed. Orion will not wait for you to fiddle with settings.

7) Expect motion, not detail

With binoculars, you are not going to see the capsule’s shape. At best, you are looking for a star-like moving point of light sliding through the binocular field.

8) Have a backup plan

If the binocular attempt proves too tough, switch to a small telescope if you have one. Spaceweather says Orion should be comfortably within reach of a 6-inch scope during the broader Day 1 window, even away from the brightest perigee moment.

What I’d tell casual skywatchers

If you have binoculars and a little patience, yes , I think this is worth trying.

Not because it will be easy, but because the thought of catching a crewed Moon spacecraft from your own backyard, even as a fleeting moving point of light, is the kind of thing that reminds us just how amazing modern skywatching can be. We are no longer limited to the Moon, planets, star clusters and meteors. Every so often, human spaceflight itself becomes part of the observing list.

And that is pretty special.

Takeaway

The best binocular chance to spot Orion appears to be during its April 2 closest Earth pass, when Spaceweather estimates it could briefly brighten to around magnitude 7 to 9. That puts it within possible binocular reach, but the challenge will be its very fast motion and the uncertainty in brightness. The best strategy is simple: use JPL Horizons for your location-specific coordinates, get outside early, brace your binoculars, and treat the whole thing like a fast-moving celestial scavenger hunt.

The post Could You Really See NASA’s Orion Moon Capsule With Binoculars? appeared first on The Night Sky Guy.

For skywatchers, this is one of those rare moments when human spaceflight and backyard astronomy may overlap in a very real way.

According to a visibility analysis published by Spaceweather.com, NASA’s Artemis II Orion capsule could become bright enough during a few parts of the mission to be spotted with amateur equipment, and in the very best case, even binoculars may be enough for a brief look.

That does not mean Orion will be easy to catch.

Brightness is only part of the challenge. The spacecraft will also be moving quickly across the sky, especially during its closest passes to Earth, so success will come down to a mix of timing, tracking, and telescope size.

The best days to try

The strongest viewing opportunities appear to come on April 2, right after launch, and again on April 10, as Orion returns to Earth. During its first day in space, the capsule is expected to range from about 30,000 to 75,000 km away, putting it around magnitude 10.7 to 12.7 , well within reach of a typical 6-inch backyard telescope.

The real highlight may come during Orion’s closest pass later that same day. Around 23:00 to 23:30 UTC on April 2, the capsule could swing to only about 6,700 km from Earth and briefly brighten to around magnitude 7 to 9. That is bright enough for binoculars, although Orion will also be moving several degrees per minute, which could make it surprisingly tough to track.

When Orion starts to fade

By April 3, Orion should still be visible in amateur scopes, especially early in the day when it is expected to sit near magnitude 13. Later that day, as it heads farther into space, it may fade to around magnitude 14.5, putting it more in the range of a 10- to 12-inch telescope. By April 4, it could be down to about magnitude 15.3, right on the edge for a 12-inch backyard scope.

From April 5 to April 9, during the outbound cruise and lunar flyby portion of the mission, Orion is expected to dim to around magnitude 16 to 17. That is beyond the reach of most backyard telescopes and into the realm of large instruments and long-exposure imaging.

The return leg brings a second chance

The good news is that Orion should brighten again on the way home.

On April 10, the capsule is expected to climb back into amateur range, starting around magnitude 14.4 early in the day and improving to roughly magnitude 12.8 by 18:00 UTC and magnitude 11.1 by about 22:00 UTC. In other words, the return leg could offer another excellent chance for backyard observers.

There may also be a brief final viewing window on April 11 before Orion re-enters Earth’s atmosphere, but that opportunity is expected to be short.

Bottom line for skywatchers

If you want to try spotting Artemis II’s Orion capsule, your best odds come during the first three days of the missionand again during the final return approach, with April 2 and April 10 standing out as the prime dates. Spaceweather.com notes that the brightness estimates carry an uncertainty of about plus or minus 2 magnitudes, so actual visibility could end up a little better, or a little worse, than forecast.

Still, the possibility is remarkable.

We may be heading into a moment when amateur skywatchers can do more than follow a crewed Moon mission on a screen. Some may actually be able to track part of it from their own backyard.

The post Can You See NASA’s Artemis II Orion Capsule With a Backyard Telescope? appeared first on The Night Sky Guy.

Skywatchers have a new comet to follow, and it could become one of the more interesting celestial stories of the season.

Comet C/2026 A1 (MAPS) is currently brightening as it plunges inward toward the sun. Its moment of truth comes in early April, when it will swing extremely close to the solar surface. If it survives that fiery encounter, observers may get a chance to spot it low in the western sky after sunset.

That said, this is not the kind of comet anyone should overhype just yet.

Sungrazing comets are notoriously unpredictable. Some brighten dramatically and put on a memorable display. Others fade, fragment, or vanish altogether before they ever become easy public targets. For now, this comet falls into the “promising, but uncertain” category.

What makes this comet special?

C/2026 A1 is classified as a sungrazer, which means its orbit carries it extremely close to the sun. These are some of the most dramatic comets in the solar system, but also some of the riskiest for the comet itself.

As the comet nears the sun, intense heat and solar forces can cause it to brighten rapidly. But those same conditions can also tear it apart. That uncertainty is part of what makes these objects so fascinating to follow.

In this case, skywatchers are watching closely to see whether the comet survives its closest approach in early April. If it does, it could emerge as a photogenic twilight object, possibly with a noticeable tail.

What beginners should expect

At this stage, this is still not a guaranteed naked-eye comet.

For most observers, the best chance of catching it will likely begin with binoculars or a small telescope, especially during the second half of March and into early April. The comet is expected to stay low in the western evening sky, where twilight and haze often make faint objects harder to see.

That means beginners should go in with realistic expectations. Even if the comet brightens nicely, it may still be a challenge because of its low altitude and closeness to the sunset glow.

Still, these are exactly the kinds of sky events that can be rewarding to follow night by night.

Best practical observing advice

If you want your best chance at seeing this comet, keep these tips in mind:

1. Choose a wide-open western horizon

A flat, unobstructed view is critical. Trees, buildings, hills, and even a thin layer of haze near the horizon can make the difference between seeing it and missing it.

2. Start scanning after sunset

Wait until the sun is fully below the horizon and the sky begins to darken. The comet is expected to appear low in the west, so timing will matter.

3. Bring binoculars first

Even if the comet becomes brighter, binoculars will give you a much better chance of spotting it in twilight. A small telescope may help too, but binoculars are often the more practical tool for sweeping a broad area of sky.

4. Watch from night to night

Comets can change quickly. One evening may be disappointing, while the next may offer a much better view if the comet brightens or develops a stronger tail.

5. Keep expectations flexible

This may turn into a lovely twilight comet. Or it may not. That is simply the nature of sungrazers.

Important safety reminder

Never search for a comet close to the sun while the sun is still above the horizon.

This is especially important for beginners. Sweeping the sky with binoculars or a telescope before sunset can accidentally bring the sun into view and cause serious eye damage. The safe rule is simple: wait until the sun has completely setbefore searching.

Skywatching Tip:
For the best chance of spotting this comet, head to a location with a low, unobstructed western horizon and begin watching about 20 to 40 minutes after sunset.

Why this could still be worth watching

Even if C/2026 A1 does not become a major naked-eye spectacle, it still has all the ingredients for a fun observer’s challenge.

There is something special about following a comet in real time as it changes from night to night. You are not just looking at a fixed object in the sky. You are tracking a visitor from the outer solar system as it reacts to the intense environment near the sun.

And if it does survive its solar encounter intact, we could end up with a beautiful bonus object in the evening twilight.

Bottom line

Comet C/2026 A1 (MAPS) is a comet to watch, not a comet to promise.

Right now, the safest bet is to think of it as a possible binocular comet for late March and early April, with a chance of becoming more impressive if it survives its close pass by the sun. For skywatchers, that makes it well worth following.

So get your binoculars ready, scout out a clear western horizon, and keep checking updated comet charts. Sometimes the most exciting sky events are the ones that keep us guessing.

For astrophotographers and casual skywatchers alike, satellite streaks are becoming one of the biggest new headaches in the night sky. What used to be an occasional surprise in a long exposure is now showing up more and more often, cutting through images of comets, nebulae, star fields, and even simple wide-angle sky shots. Spaceweather.com says thousands of Starlink satellites are already in orbit, with far more planned, while Amazon’s Project Kuiper and China’s proposed Guowang and Qianfan constellations could add many thousands more to the mix. 

That means the challenge is not going away anytime soon. In fact, for anyone who loves photographing or simply enjoying a dark, natural sky, this may become one of the defining astronomy issues of the coming years. Because of that growing impact on observers, Spaceweather.com has launched a new Starlink Statistics tracking page and says it plans to expand coverage to other megaconstellations as they become more important.   See it here: https://www.spaceweather.com

Have you noticed more satellites crossing the night sky lately, or is it not affecting your observing/astrophotography yet?

New observations from the James Webb Space Telescope have now ruled out any chance of a lunar impact on December 22, 2032. Scientists say the asteroid is now expected to miss the Moon by about 21,200 kilometers, ending earlier concerns that gave it a small 4.3% chance of striking our natural satellite.

The updated orbit comes from Webb observations taken on February 18 and 26, 2026, which tracked the extremely faint asteroid with far greater precision than before. Researchers also got matching results from archival images that traced the object back to 2016, giving astronomers two independent lines of evidence that the Moon is safe.

While a Moon strike would not have threatened Earth directly, the case became an important real-world test of planetary defense techniques. It also highlighted how professional observatories and skilled amateur researchers can work together to refine the paths of potentially hazardous space rocks.

But there is also a little talked about dark-side to such a collision with the moon too. A major impact on the Moon wouldn’t just be a spectacular sky event, it could also create a huge and dangerous debris problem. Any satellites, spacecraft, or future infrastructure we have in the Earth-Moon environment could be at risk from an expanding cloud of fast-moving debris, and the domino effect of collisions could make the situation even worse.

Our near-space environment could end up polluted and dangerous to cross for a long time afterward. And hopefully, with what we’ve learned from NASA’s successful asteroid redirection mission, we may one day be able to apply that same kind of planetary defense know-how to nudge an incoming object off course before it ever hits the Moon and creates that kind of mess. 

If a large asteroid ever did hit the Moon, would you want to watch it happen live?

In the early morning hours, the 94%-illuminated moon will be hanging about halfway up the western sky, nestled within the constellation Taurus the Bull. Just a short hop — about five degrees to its upper left (that’s roughly the width of your three middle fingers held at arm’s length) — you’ll find a faint, misty patch of light. That’s the Pleiades open cluster, a dazzling collection of young, hot blue stars born together roughly 100 million years ago.

Now, with the moon shining so brightly, the Pleiades will be fighting a bit of glare — but don’t give up! Grab a pair of 10×50 binoculars and you’ll easily make out their sparkle. You’ll spot the seven brightest jewels of the cluster — Merope, Electra, Maia, Taygete, Asterope, Alcyone, and Celaeno — surrounded by a swarm of fainter suns, part of a cosmic family numbering over a thousand.

If you want to stretch your observing skills even further, look just a little below and to the left of the Pleiades — about the same five-degree distance — to find the spot where the planet Uranus hides in the background stars. With a magnitude of +5.6, it’s far too faint to see without optical help, but through a telescope with at least an 8-inch aperture, you’ll be rewarded with a delicate bluish dot. It may look small and unassuming, but that tiny speck is a gas giant four times wider than Earth, sitting 1.7 billion miles (2.8 billion kilometers) away.

So, before the sun rises and the sky brightens, take a few quiet minutes to soak in this moonlit encounter between our familiar satellite and one of the most enchanting clusters in the heavens.
