A star to the left. Blue spiral galaxy in the middle with smaller blue irregular galaxy on the right. Lower right red source with some red blobs next to it. Dark spots litter the background, which are a common issue in this program.

Small galaxy group with #JWST MIRI.

Big spiral is AGC 210801, but I think the smaller blue galaxy to the right (LEDA 1748854) is the target of the spectroscopy.

Red galaxy on the lower right is Z 127-57 and star on the left is BD+26 2255 (F-type).

Artemis III Moon Rocket Core Stage on its way of the assembly facility.

NASA moved the core stage, or the largest section, of the SLS (Space Launch System) rocket that will launch the crewed Artemis III mission in 2027 from the agency’s Michoud Assembly Facility to the agency’s Pegasus barge in New Orleans on April 20.

Region 4419 is still alive - new spots of opposite polarity in the trailing section - one of them could count as a delta spot - It remains to be seen whether any magnetic stress will build up

This anaglyph shows an interesting pattern of fractures. It may be incipient chaos formation. A digital terrain model can help to figure out what's going on.

Enhanced color image shows a close-up of extensive, large dunes in the north polar region of Mars. There is seasonal, bright ice on the slipface of many of the dunes, and dark patches between the dunes as well.

HiPOD: Translucent Ice on Dunes

At the time of year we took the image, the whole scene was probably covered in carbon dioxide ice. Some of this ice is translucent, so you can see the dark dunes through it.

"ISS from yesterday passing over at 9:15 in the morning. It passes earlier each day, with its illumination by the Sun shifting from the far side to the front (you might see a very thin flare on the Columbus and Japanese modules on the left). Soon, it will be illuminated on the Earth side as it passes when the Sun is below the horizon. This configuration makes it much brighter and easier to image, but for now it’s very faint and lit by Earthshine.

All of these growing constellations aim for thousands of satellites in the future
Ten years ago there were only about 1,400 active satellites--TOTAL. The current near-Earth environment is 10 times as busy and growing more crowded every day. What could go wrong?
arxiv.org/abs/2512.09643

Who is second to Starlink? Biggest runner-up is OneWeb (operated by Eutelsat), with 656 satellites. Amazon Leo (formerly Project Kuiper) comes in third with 233 satellites. Guowang, Starshield, and Thousand Sails are still trying to join the conversation with starter swarms of 100 to 200.

Although Starlink program has attracted attention for launching more than 10,000 satellites, they're not the only ones orbiting🌎. Population of other satellites has been growing, too. Satellites not named "Starlink" now total almost 5,000, bringing the grand total of all satellites to ~15,000

"The image shows the Rosette Nebula (NGC 2237) in the constellation Monoceros with a prominent satellite flare crossing the field of view. A closer investigation using the "Stellarium" software revealed that the object was the US military satellite FIA Radar 4. The satellite flies in an orbit of 1,107 km height. It crossed my field of view within 15 seconds. The maximum brightness was close to Venus with -4.5 mag at exactly 19:52:12 UT on March 7, 2026. At that time, I was shooting the Rosette Nebula from my balcony under a Bortle 6 sky, taking a series of 2-minutes frames with an 80mm Apo and a ZWO ASI 2600 MC Pro cooled camera with an Optolong L-eNhance duo-narrowband filter. The image shown is a composite of 105 frames without the flare plus the single frame (19:51:55 - 19:53:55) with the flare. Details: Object: NGC 2237 (Rosette Nebula) with a flare of NORAD 41334 (FIA Radar 4) Instrument: 80mm refractor f/6 with 0.8 flattener (focal length 384mm), Optolong L-eNhance duo-narrowband filter (H-alpha plus O-III) Camera: ZWO ASI 2600 MC Pro Color, cooled at -10° Celsius Exposure: 106 x 2 min (~3.5 hours total) Processing: Astro Pixel Processor (stacking), Lightroom (denoising, gradation curve)"

Five years ago, Ingenuity took its first flight on Mars! Complete 72, originally intended to make only five.

After 72 flights, 17 km ​ flown, and a top altitude of 24 meters, Ingenuity ended its mission on January 25, 2024.
