Geologic Core Sample

xkcd.com/3171/
Comic: Typical Geologic core sample. [Cylindrical core sample with labels for difference sections from top to bottom] Topsoil, till, granite bedrock, bottomsoil, roof of subway car, floor of subway car, more granite, municipal water main [gouge in core sample], slightly different granite, piece of screaming spelunker’s forearm, cool crystals with no resale value, mangled fragments of drillbit from previous attempt, some boring intrusive rock that’s basically granite but has a name like “diorite” or “Andalite” that you always have to look up, netherrack, Balrog wing. [break between next chunk of core sample] Granite, topsoil, cement, floorboards, carpet, possessions of a confused and angry homeowner in the other hemisphere.

Introduce yourself with four spaceships.
Stereographic projection of a selfie captured by the Perseverance mars rover. The rover is standing on the slopes of the outer rim of Jezero crater, facing Nili planum, a mostly flat landscape ouside the crater with small hills. A core hole is visible in front of the rover from the last coring operation. The old, meandering, sand covered river bed of Neretva Vallis is visible in the distance on the left, and a whiteish dust devil can be seen inside it.

The Sun eclipsed by Earth as seen by the returning Apollo 12 crew. This colorization of a B&W photo suggests how a composite made from different exposures might have appeared if they hadn't run out of color Hasselblad film. Hopefully one day this sight will be captured with capable color cameras.
This photo shows the Sun being eclipsed by Earth as seen by the returning Apollo 12 crew. It was colorized atop a B&W photo and shows the colors reported by the crew at the time as well as those marginally recorded on 16mm film. Note the compressed Sun reflection recording its flattening by the refraction of Earths atmosphere.

A very close view of the craters that cover the surface of Saturn’s icy moon Rhea. NASA’s Cassini mission made this flyby in January 2011, passing within 76 kilometers (47 miles) at a speed of 8 km/sec (18,000 mph). This image had a resolution up to 22.6 meters per pixel towards the closer terrain.

Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪

🔭 3I/ATLAS: A View from Planet Earth

Image Credit & Copyright: Rolando Ligustri

apod.nasa.gov/apod/ap25112...
Now outbound after its perihelion or closest approach to the Sun on October 29, Comet 3I/ATLAS is only the third known interstellar object to pass through our fair Solar System. Its greenish coma and faint tails are seen against a background of stars in the constellation Virgo in this view from planet Earth, recorded with a small telescope on November 14. But this interstellar interloper is the subject of an on-going, unprecedented Solar System-wide observing campaign involving spacecraft and space telescopes from Earth orbit to the surface of Mars and beyond. And while the comet from another star-system has recently grown brighter, you'll still need a telescope if you want to see 3I/ATLAS from planet Earth. It's now above the horizon in November morning skies and will make its closest approach to Earth, a comfortable 270 million kilometers distant, around December 19.

I'm glad this is finally out after the government shutdown!

JWST's images of dusty, spiraling shells around Wolf-Rayet star binaries are my favorite.
stsci.edu Space Telescope Science Institute @stsci.edu · 6d
Three #NASAWebb discoveries in ONE! Webb shows there are FOUR dust shells (only one was previously seen), allowing researchers to narrow the stars’ orbit of one another to a LONG 190 years. Plus, they confirmed a third star is part of the “party”: https://bit.ly/4n1tpas 🔭 🧪

And something slightly OT. C/2025 K1 (ATLAS) during a tracking pause last night. 50 frames stacked and a single frame, from a bit earlier in the evening, to visualize the three fragments a little more clearly.

TKS: Vladimir Chemolei's space station logistics craft. Designed to support Almaz military stations, it could carry a crew of three. Despite successful test flights, it never flew a crew. Rather, the design was reconfigured and used as Mir and ISS modules (Zarya and Nauka).

Second morning in a row out imaging interstellar comet 3i, and I've found a much better spot with a much clearer view so no rainbow streaks or tree branches blocking the comet!

IRIDESCENT CLOUD ON MARS

Iridescent clouds over Gale Crater (enhanced color) - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2qJvryP
This enhanced color panorama was taken by Curiosity's Left Mastcam after sunset on Sol 3724 (27 January, 2023). It shows an iridescent high altitude cloud, likely made from CO2 ices. The sun has already set on the ground, but continues to illuminate this cloud which is likely at 60-80km altitude. The iridescence (rainbow effect) is caused by diffraction at sub µm ice particles. More information: doi.org/10.1029/2024GL111183 This panorama was stitched from 14 MAST_LEFT images from the PDS. The individual images were color calibrated to approximate what the human eye would see. The panorama was further enhanced to emphasise cloud structure and subtle color variations. See here for an unenhanced variant of the panorama: flic.kr/p/2qJwraX LMST: Sol-03724M18:52:13 Sun: Az: 276.2 deg, El: -5.9 deg Rationale: Characterize potentially iridescent ice clouds in twilight Credit: NASA/JPL-Caltech/MSSS/Simeon Schmauß

Gigantic jet TLE above Mexico (crop) - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2rhxUhJ
On July 3rd, astronaut Nichole Ayers photographed a gigantic jet from the ISS. These rare upward directed electrical discharges extend ~90-100 km high into the mesosphere. The jet originated from a thunderstorm over Northern Mexico, with city lights from South Texas and the green airglow layer visible along Earth’s limb. I processed this image from the RAW file, adjusting the color profile, white balance and contrast and applied Lightroom's machine learning denoise with low strength. The RAW was provided to me by Frankie Lucena, his analysis of the event, correlating it to measurements from the Geostationary Lightning mapper and ELF-VLF radio signals can be found here: spaceweathergallery2.com/indiv_upload.php?upload_id=224355 Original image listing in the NASA archive: eol.jsc.nasa.gov/SearchPhotos/photo.pl?mission=ISS073&amp...
