🗣️ Durante los días 18 y 19 celebramos en el IAA los “PhD & JAE-Intro Days”, un evento en el que estudiantes de doctorado y máster exponen sus proyectos y resultados de investigación Dos días muy productivos para nuestra próxima generación investigadora! sites.google.com/view/phdjae-...

Very useful #comet ☄️ thermal modelling group meeting this morning. Seems I have basically managed to make myself organiser of a seminar series! Also, since I took the meeting from home, there was a special guest appearance... 😸 #CatsOfZoom

The time has come. All coffees are ice coffees from now on

Could tonight be the night!? #Arsenal

I can see my (old) house in there 😀🇫🇷

🎵 It's student presentation time 🎵 #JAE-Intro day at @iaacsic.bsky.social. Students are presenting the work they've been doing in their JAE internship and PhD projects. My student, Alba, is presenting her project on the analysis of historic #comet ☄️ non-gravitational forces and orbits

Very interesting thread (like another commenter, I will quite enjoy saying yes I speak Latin... the colloquial French and Spanish versions!), and the posts on people's love of categorising relate to the Pluto planet argument that's reared up again recently!

Good to know! In all seriousness, this is very interesting and, as the thread goes on to show, a perfect example of how dynamics can be used to obtain physical properties! Something I am working on a lot :)

Earth eclipses the Sun as seen by Artemis II on Orion. Satellites showing off as usual...

I'm afraid you've loaded the opening credits of the expanse there and not really images..surely!

This is incredible. The new NASA image release from #Artemis includes a sequence of 'Hello World' still photographs. I've been processing / animating them and here's what the original didn't show us: Satellites, including their solar arrays, lightning storms and dancing aurora!

This looks very cool! And I'm glad @esa.int seems to be increasing its cultural reach. I recently got an ESA #Playmobil astronaut and a t-shirt for my son from the #ESTEC shop, and he loves them ☺️ Let's make ESA, our space agency, as well known as NASA!

Containing lots of lovely details of LSST's astrometry of cometary objects ☄️. I will be reading this and thinking about the context of @cometinterceptor.bsky.social targets 😀

Seminar delivered @ua.es. Of course I had to wear this t shirt today... #Maythe4th #StarWars. And I even got to have a full English breakfast before, courtesy of Alicante being quick the destination for UK tourist 😅

And here's a (long-overdue) photo of the members of the @cometinterceptor.bsky.social team who attended the SWT in-person!

Only been back a week and I'm travelling again! We are doing a home exchange on the coast near #Alicante for the 'puente' long weekend. After, I will take the opportunity to visit @ua.es and give another seminar on #comets thermal modelling and dynamics :)

This is great! And I have to say, I am very happy with mine... a line of #lava 🌋 aaand a crater ☄️! Awesome science.nasa.gov/mission/land...

Filing my expenses claim for this trip and I might just keep one of these, it looks so fancy! @esa.int ☺️

☄️Planetary scientists are invited to submit an abstract for the #EPSC2026, which will take place in The Hague, 6–11 Sept 2026. 🗓️ Abstract deadline is 13 May 👉 www.europlanet.org/epsc2026-call-for-abstracts-now-open/

This week the CI Science Working Team convened at a sunny ESTEC ☀️ thanks to everyone who attended for 3 days of discussions and presentations on all things comets! ☄️

In all the excitement this week I forgot to post: Abhinav's paper on dust transport across #comet #67P ☄️has been published! This came out of an excellent week spent working with @spacemarschall.net and @browngeomorphlab.bsky.social at #Nice observatory www.sciencedirect.com/science/arti...

Love this shot of Saturn near the solstice. The rings are casting those shadows on the cloud tops.

Tavelling to the Netherlands tonight 🇳🇱 Tomorrow I will give a seminar @ TU Delft, and catch up with my old project student, Pieter. Then I'm off to ESTEC for a @cometinterceptor.bsky.social meeting. Looking forward to visiting @esa.int for the first time! 😀 bsky.app/profile/nick...

It worked! Check out my handle 😀🇪🇺

If you're European, you now have a great and well-funded PDS in EU soil, governed by EU laws, run by awesome folks. Moving your account to Eurosky is easy, and you won't notice the difference afterwards. Please take a few minutes and do the jump 🇪🇺

Both my group and the department have now organised group photos next week while I'm away, so I'm probably gonna be a ghost from now on 😅 Just registering this now: I DO ACTUALLY EXIST AND WORK HERE!

For some reason the remote for the TV/screen in the meeting room opposite my office is kept at the front desk. Sometimes it randomly turns on very loud and I have to walk all the way there to turn it off. Today it's muted but playing this... Actually very calming 😅

Enjoying the ever-changing sequence of error messages from BlueSky today. Latest was "Not Found. Not Enough Resources". Pretty sure they'll be asking me to build more pylons next...

There's only about 8.6 Moon's worth of moons in the Solar System. (7.3e22 kg vs 6.3e23 kg)

Did the Artemis II mission get you excited about humanity’s quest for the stars? Follow this astronomy feed, which highlights some of Bluesky’s best posts on our fascinating universe: bsky.app/profile/emil...

✅ #ArtemisII update: European Service Module's last trajectory correction burn 👍

I see the names of these Estrack ground stations when using spacecraft tracking data 🛰️ to inform #comet ☄️ trajectory models...Cebreros, New Norcia...they have almost mythical sounding names. Nice to see they are indeed real places on #Earth !

New favorite shot, European Service Module with ESA logo, Dutch Solar Array Wings, the Moon and Earth :) Hi-res here: images.nasa.gov/details/art0... #ArtemisII

✅ #Artemis II update: 'Earthset', 6 April 2026, and 'totality', 7 April, seen from lunar orbit, the Moon eclipses the Sun, a view few humans have ever witnessed (pics: NASA) 🔗 www.nasa.gov/gallery/jour... @exploration.esa.int l

The NASA one just a little bit bigger of course 😅

Cool project. Collaborating with astronauts! 🔭👩‍🚀

Ah so much for A1 MAPS ☄️being a bright visible comet! A shame but, if my french is to be believed, it looks to have completely disintegrated on its close pass to the Sun

The bellow + this fantastic blog post + a colleague pointing out that @cometinterceptor.bsky.social will be more like #Giotto (fast flyby) than #Rosetta (extended rendez-vous) has got me reading a load of #comet Halley ☄️ papers from before I was born, today 😀 www.drewexmachina.com/2016/03/06/t...

😮 Awesome views from Day 2 of #Artemis II this morning. @exploration.esa.int @esaearth.esa.int

"that's the assumption anyway" has absolutely killed me 🤣

Vital #ScientificComputing information!

*Hastily converts all my #comet activity modelling code to output in Olympic swimming pools per day rather than SI units* 😅
