An image with a black background. The planet Uranus is a glowing orb near the center surrounded by rings. The planet appears blue with a large, white patch taking up the right half. The patch is whitest at the center, then fades into blue at it expands from right to left. A thin outline of Uranus is also white. Around the planet is a system of nested rings. There are faint orange and off-white smudges, some oval, some circular, that are background galaxies scattered throughout the image. Several bright blue point sources closer to Uranus are the planet’s moons. There is also a bright star at the left of the field, with 8 diffraction spikes.
The planet Uranus on a black background. The planet appears light blue with a large, white patch on the right side. On the edge of that patch at the upper left is a bright white spot. Another white spot is located on the left side of the planet at the 9 o’clock position. Around the planet is a system of nested rings. The outermost ring is the brightest while the innermost ring is the faintest. Unlike Saturn’s horizontal rings, the rings of Uranus are vertical and so they appear to surround the planet.
At center is the planet Uranus, a blue globe with a large white spot occupying most of the planet. It’s surrounded by a series of rings that get brighter as you move outward. Beyond the rings are 14 moons appearing as points of light. The moons vary in brightness with the brightest, Miranda, just above 9 o'clock.
The planet Uranus appears as a smooth, bright cyan disc at the center, its atmosphere reveals soft, hazy tones of blue. Surrounding the planet is a vivid reddish glow, forming a diffuse halo that contrasts strongly with the cool blue of the planetary disc. Encircling Uranus are several thin, concentric rings, visible as pale grey arcs. Subtle variations in brightness can be seen across the planet\u2019s face, with slightly brighter patches near the limb, hinting at atmospheric structure.

NASA quietly updated its potential launch windows for its delayed moon mission, apparently now targeting March 6-11
The Pleiades star cluster (M45) captured over 25 hours. The blue glow is starlight reflecting off interstellar dust. The surrounding brown structures are the Integrated Flux Nebula, incredibly faint clouds lit by the glow of our entire galaxy.

Intergalactic Wanderer NGC 2419 globular cluster astronomy
This is globular cluster NGC 2419, also known as the Intergalactic Wanderer, found in the constellation Lynx, where globular clusters wouldn't normally be found. It orbits the Milky Way every every three billion years and its orbit takes it further than the Magellanic Clouds.

I understand that people are clowning on this person for using AI extensively for their work, and I won't pass explicit judgement on that, but this does highlight the extreme importance of off-site backups and versioning your documentation/work.

January 7th is National Old Rock Day! Well here is an old rock! These white circles are cross sections of Archaeocyathids. These were a type of sponge that built reefs during the Early Cambrian. This comes from the the Forteau Formation in southern Labrador, Canada. Over 516 million years old!

Stuff like this makes me so sad... Libraries are magical places. #Science #Space #NASA
There's a famous Feynman interview where he explains why ice is slippery. It turns out there's more to the story involving shear-stress and slippage of disordered ice layers. Things we experience every day still generate novel thought and research. #Science #Physics

Hey Martians, did I mention we now also have a video of epic Phobos passing over a Martian dust storm near Pavonis Mons? 🌪️🌋🥔

Absolutely disgraceful by OU. They've thrown their graduate student under a bus. This was regraded too by the actual instructor-of-record professor. Even in the situation that the grade was found unfair (which it isn't), you correct/instruct your TA and move on, not succumb to outside pressure.
What's next? We'll be allowing young earth creationism in astronomy 101?

A comet among the stars. The comet is visible to the left and has a tail pointing towards the left. Some distant galaxies are also visible (like spiral galaxies NGC 3356 and NGC 3362 towards the right). The image was obtained with an 8-inch f/4 telescope and an unmodified M4/3 camera. 63x30s images edited with DSS, SIRIL and GIMP.
A fairwell to #3I/ATLAS, the interstellar visitor, as now it is moving away both from the Sun and Earth. It has dimmed to about mag 12 and has a tail pointing towards the Sun. It will continue getting dimmer and won't be visible in just a few months. #cometWatch #astrophotography

@dpiponi.mathstodon.xyz.ap.brid.gy Gorgeous LEGO model. I have the Saturn V but haven't assembled it yet.
When Star Trek the Movie came out back in '79 it had a much criticized sequence of shots where the camera basically drools over the Enterprise (1701A) in dry dock. But I was the target audience.
I hope we get a Bird of Prey next. We probably also have enough […]

We got to the final listed track, track 15 "The Fate of Thomas Light" and it's the saddest bit of music I've listened to in awhile. Everybody in the Bandcamp livestream was devastated. This can't be the end of Act III. #Protomen #Music #RockOpera
A bright green shape at lower left, the coma of interstellar comet 3I/ATLAS, leaving a faint trail of gas from lower left to upper right right behind it. The background is a dense starfield, with some bright, nearby stars at upper centre.
