the discord link above is where I got it from. fredk is an avid image processor but I'm not aware if they have a main account for posting (maybe @npub1mvn…s2a0 or @npub1pct…f46x know?). The source photos are in the public domain & I bet there'll be more processing by others ( @npub1tjz…mk9e ?) since there appears to be more exposures, only of varying quality (the lighting conditions are challenging but so gorgeous...)

The "Hello World" photo from #ArtemisII did not come alone. Here's an animation put together by fredk of multi exposures (UMSF After Party https://discord.com/channels/1290524907624464394/1305654861496451182) showing a receding Earth in moonshine.
Crank up the brightness and behold lightning in Africa & South America, changing aurorae at the poles... and satellite glints all over the place, most visible at 3 and 9 o'clock 🤯
I remember ppl suggesting using stuff like this to do SETI...

There sure is going to be timelapses, but here's a teaser with some SVT footage that wasn't affected by the hard winds, at something like 15x speed.

Interrupting my sequential traverse of abstracts; one thing lead to another and I ended up looking at the #LeopardSpots (+ "poppy seeds") papers, with "strong" wording for potential biosignatures.
Look at the much longer author list of this first one:
Hurowitz et al: "The Detection of a Potential Biosignature by #PerseveranceRover"
https://www.hou.usra.edu/meetings/lpsc2025/pdf/2581.pdf

Not what I was expecting, they looked too small to me. I was almost sure it was wild boar (because of other bones around), maybe deer, but the latter I can see now that nope. I'll look at it closer later, gracias!

looks too "rounded" imho. Have you a special layer or smth in QGIS for registering where all these are found (there seemed to be more in Mt Washburn)?
