There not only an expansion of the bright material, but also new bright material appearing (center in the upper left). Maybe an astronomer can explain this. Material that only now gets shocked?

The Great Nebula in Orion, an immense, nearby starbirth region, is one of the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the featured deep image in assigned colors highlighted by emission in hydrogen, wisps and sheets of dust and gas are particularly evident.

The Great Nebula in Orion can be found with the unaided eye near the easily identifiable belt of three stars in the popular constellation Orion. In addition to housing a bright open cluster of stars known as the Trapezium, the Orion Nebula contains many stellar nurseries.

These nurseries contain much hydrogen gas, hot young stars, proplyds, and stellar jets spewing material at high speeds. Also known as M42, the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

Probably the brightest and most well defined moon ring ive ever seen.

The featured image from the American Museum of Natural History's Hayden Planetarium Space Show, Dark Universe, highlights one example of how pervasive dark matter might haunt our universe.

In this frame from a detailed computer simulation, complex filaments of dark matter, shown in black, are strewn about the universe like spider webs, while the relatively rare clumps of familiar baryonic matter are colored orange.

These simulations are good statistical matches to astronomical observations. In what is perhaps a scarier turn of events, dark matter -- although quite strange and in an unknown form -- is no longer thought to be the strangest source of gravity in the universe. That honor now falls to dark energy, a more uniform source of repulsive gravity that seems to now dominate the expansion of the entire universe.

Colors and curves in Photoshop were just personal preference.

Figured out a new method for capturing the moon on seestar s50, first turn on the LP filter (you wanna do this because triton emits more in this spectrum, so it isolates it from the glare of neptune) then turn on 4k mode, then let it run for 1 minute. then use a RAW video composite to capture the planet. Put the two together and boom! You now have a high quality composite of neptune and triton side by side.

The first photos taken from space were taken on October 24, 1946 on the sub-orbital U.S.-launched V-2 rocket (flight #13) at White Sands Missile Range. Photos were taken every second and a half. The highest altitude (65 miles, 105 km) was 5 times higher than any picture taken before.

Evan McKay explained in his post

Last year, I attempted my first deep-sky photograph, capturing the Andromeda Galaxy passing above the snow-capped Mount Taranaki. This was a shot I had wanted to capture for many years, and I had only recently acquired the gear needed to make it happen. I was so captivated by the result that it inspired me to invest in specialised deep-sky equipment, starting with a telescope mount before adding a telescope and a dedicated astrophotography camera.

Over winter, I had very few opportunities to properly test out the new telescope, although I managed to squeeze in a few sessions to get some practice. My main goal was always to revisit the Andromeda - Mount Taranaki alignment, but I knew I was running out of time. I tried again and again, only to be thwarted by the weather on several occasions. It was incredibly frustrating, but eventually, I got the conditions I needed.

There was one catch: the Moon was up, albeit in its crescent phase. I wasn't sure whether I'd even be able to capture Andromeda under those conditions, but the results were surprisingly convincing, and I finally got the alignment I'd been chasing. As an added bonus, the setting Moon beautifully illuminated the snow-covered mountain, creating a scene I couldn't have planned much better.

One of the biggest challenges with Andromeda is its low position in the sky. From this region, it only reaches around 8–9.5 degrees above the horizon, severely limiting the amount of integration time I can collect and the clarity of the final image. Fortunately, I had some data from a previous moonless night that I could register and blend with the moonlit captures. This helped bring out a substantial amount of the galaxy's outer disc, along with some of its fainter nebulosity. I was also keen to try capturing the galaxy with a duoband filter to improve the nebulosity, but every attempt ended the same way: nothing but clouds!

So, this is the best I can manage this year. I might get another opportunity in early November to gather a little more data, but for now, I'm really happy with what I've achieved.

What I found really special with this image was that I was able to use the same exposure length for both the sky exposures and the mountain thanks to the help from moonlight. The only difference was that tracking was turned off for the mountain exposure.

The telescope has well and truly exceeded my expectations. Seeing just how much additional detail I've been able to extract compared with the 135mm lens I used last year has been incredibly rewarding. It's amazing to revisit an image that first inspired me to explore deep-sky astrophotography and see just how much further I can take it with the right equipment.

What you're seeing: The Andromeda Galaxy (M31) is the nearest large galaxy to our Milky Way, about 2.5 million light-years away, with roughly a trillion stars. The two smaller galaxies orbiting it are M32, the compact bright one at the upper left of the core, and M110, the larger, fainter elliptical. The pink-red knots strung along the spiral arms are clouds of glowing hydrogen where new stars are being born, and the dark lanes are dust.

How it was made: 65h 18m of total exposure over eight nights in early October 2026 from Nebraska, made of hundreds of individual frames stacked together. The galaxy's core is far brighter than its outer disc, so I also shot very short 5s, 15s and 30s frames and blended them in to keep the core from blowing out.

- Luminance: 27h 23m (180s and 120s subs)

- Red: 7h 54m · Green: 7h 39m · Blue: 8h 57m (180s subs)

This Rosetta spacecraft selfie was snapped on October 7th, 2014. At the time the comet-chasing spacecraft was about 472 million kilometers from planet Earth, but only 16 kilometers from the surface of comet 67P/Churyumov-Gerasimenko.

Looming beyond the spacecraft near the top of the frame, dust and gas stream away from the comet's curious double-lobed nucleus. Bright sunlight glints off one of Rosetta's 14 meter long solar arrays. In fact, two exposures, one short and one long, were combined to record the dramatic high contrast scene using the CIVA camera system on Rosetta's still-attached Philae lander. Its chosen primary landing site was on the visible hemisphere of the smaller lobe of the nucleus.

This was the last image from Philae's camera before the lander separated from Rosetta on November 12. Shortly after separation Philae took another image looking back toward the orbiter and began its descent to the nucleus of the comet.
