It got a bit lost with everything else going on this week, but my (high school!) research student, Jack, has been working with me on building a low-cost home radio telescope to map Galactic 21 cm features, and his tutorial for others to do the same is now up on arXiv:
arxiv.org/abs/2411.00057

Revisiting this data from this summer was well worth it :)
This is a training edit for getting a hang on #PixInsight. Already is much better than my previous one, but that was not difficult ^^

Katie Mack: "The End of Everything (Astrophysically Speaking)"

I'm not reading physics & astro pop sci books often (I love other subjects, just not my own!), so it took ages until I came around to this one.

It's an absolute joy.

Which may seem a strange thing to say about a book on how the universe will end, but it seriously is. Clearly written, cutting edge science, to the point, in a fun voice (+ sounds bites from @freyablekman). Recommended.

Comet Lapse ☄️

About an hour's worth of C/2023 A3 (Tsuchinshan-ATLAS) setting over a dry lake in rural Australia, as the Milky Way appears.

The very very bright thing on the left is Venus.

The completely ridiculous streaks that look like anti-aircraft fire are all spamlink and frankly I had rather not had any of those in my photos, but apparently a fascist billionaire and a US government agency get to decide that I have to 🖕
