Comet Interceptor

A Lego comet interceptor spacecraft held up in front of a blurry computer screen showing a zoom call.

Remote attending a @cometinterceptor.bsky.social CoCa team meeting, and finding my Lego model to be very useful for orientating myself around the spacecraft!

Excellent, I'll have to tell my intern! He's been doing great work on #comet ☄️ orbits perturbed by non-gravitational forces from their outgassing. We have already presented results to the @cometinterceptor.bsky.social team, and hopefully we will write a #PlanetaryScience paper on the subject!

Science In Action - Stephen Hawking gets it right again - BBC Sounds LIGO witnesses two black holes merge just how Hawking predicted.

Catch Colin Snodgrass talking ☄️ Comet Interceptor 🚀 on the BBC's Science In Action as well as @megschwamb.bsky.social on how important LSST will be for making small body discoveries: www.bbc.co.uk/sounds/play/... (from 8:30 minutes onwards!)

VLT observations of interstellar comet 3I/ATLAS II. From quiescence to glow: Dramatic rise of Ni I emission and incipient CN outgassing at large heliocentric distances We report VLT spectroscopy of the interstellar comet 3I/ATLAS (C/2025 N1) from $r_{\rm h}\!\simeq\!4.4$ to $2.85$ au using X-shooter (300-550 nm, $R\!\simeq\!3000$) and UVES (optical, $R\!\simeq\!35k-...

Today on interstellar comet ☄️ 3I/ATLAS, this time from our team with ESO's VLT: the coma shows rich atomic nickel! This entirely natural metal emission from grains was only recently (last 4 yrs) identified in Solar System comets, was in 2I/Borisov, & now in 3I. 🔭🧪

☄️ Say hello to Comet 3I/ATLAS, just the third interstellar object ever seen in our Solar System!

NSF–DOE Rubin Observatory didn’t discover the comet, but even during testing, it caught a glimpse. Imagine what we'll find once full science operations begin later this year! 🔭🧪
