Love this group picture of the "Original 7" + "Next 9" astronauts. 4 would walk on the moon. 3 more would orbit it. 2 went there twice. With the passing of Jame Lovell, they are now all gone.

I see the first articles in the UK press giving space to the claim that 3I/ATLAS is an alien spacecraft. Briefly:
It’s a comet that formed billions of years ago, passing through our Solar System.
It’s behaving like a comet.
There is no evidence it’s artificial.

The 'Infinity Galaxy' is a marvel of both destruction and creation: a violent collision of two galaxies forming a unique black hole not born from the death of a star. It reminds me of Buzz Aldrin's words upon stepping onto the lunar surface: "Magnificent Desolation" 🔭

Yesterday afternoon was spent chatting with two local amateur radio astronomers from @sherwoodobs.bsky.social. Experts in electrical engineering, they suggested a tweak to an antenna I was fiddling with, and I explained a weird sky signal that had stumped them. The perfect collaboration 🥰 🔭
