#Astrodon question:
What do people use to stack videos? I have a few hundred frames of Venus and I'd like to see what I can get out of them?
Thanks (& boosts welcome)

One narrow question in celestial mechanics has 36 papers on a single shelf here.

The von Zeipel-Lidov-Kozai resonances, curated by Evgeny Smirnov, 1962 to 2026. It opens with Kozai 1962 and Lidov 1962 — the two papers the effect is named after.

Good luck to everyone submitting their #JWST proposals today. My first version is in the bag, now to read it and find the O(dozens) of mistakes I made…. Scientific method FTW! #exoplanet #astrodon

#IFT14 orbital trajectory, and Ship 41's re-entry and water landing near Hawaii.

#IFT14 WDR for the first operational orbital Starship flight. With a test payload that's almost 52 metric tons. A full payload of V3 Starlinks would be 120 tons (comparison: Skylab was 90 tons, Polyus Полюс was 80 tons)

There are now three Chinese “SpaceX Starship” knockoffs in development. One powered by the BF-20 methalox FFSC engine (Landspace). Another with YF-215 (CASC). And a third with Tianhuo-21 (Space Pioneer, pictured next to Raptor 3). All FFSC methalox Raptor-like engines.

Academic conferences are exhausting: fell asleep around 11 at night yesterday, fully woke up at noon today.

(Was still 100% worth it.)

Personal conference challenge: ask at least one (good, honest) question every day.

The happineas when your PhD student gives an amazing talk at a conference 🥳 🥳 🥳

(And gets a lot of questions from senior folks in the community that he deals with well 💚)

Leiden Observatory Masters graduate Valerie Bakker leads a paper on “The Hill sphere transits of Beta Pictoris c and the search for another 1981-like event” where we (sadly) did not find circumplanetary dust… but maybe it’s already condensed into #exomoons ..? #astrodon #exoplanets
