Our latest paper on #comet activity ☄️ is out in Monthly Notices @rasjournals.bsky.social! Quite excited by this work, which marks the confluence of two separate projects and with more to follow (hence the I 🙂) academic.oup.com/mnras/advanc...

Watching the snows come and go is fun!

I stacked 62 raw frames from the Artemis II crew into one HDR picture: a total solar eclipse, seen from behind the Moon. Thank you Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen for shooting it, and NASA for releasing the raws this month. #ArtemisII #Astrophotography

Nobel prize winner Michel Mayor is giving a public talk on #exoplanets in #Granada next week. Signup at the end of the thread

Nearly there! 🙂

I did know about Stickney but, to my shame, I did not know about Chloe Angeline Stickney Hall! So cool!

From the opening frames, I could not have guessed where this was going. The modern world is simply incredible

I love that the ship that caries spacecraft to French Guiana has sails and comes from #Marseille 🙂🇫🇷⛵

ah yes, 5 days (3 working days!) to write and submit a 10 page proposal for a 4 year/half a million euros grant. That seems reasonable...!

And Lift Off! A glorious launch of #MMX, the start of an amazingly awesome 5 yr round trip to Mars' moon Phobos. 1yr to get there, 3yrs exploration landing on the surface (twice), then 1yr to get home with the bounty (2tbls of Phobos dust), arriving in the Australian outback in 2031! 🥳🔭🧪🛰️🚀

The MMX spacecraft will be launching from Tanegashima in a few hours. The English-language livestream will be available at www.youtube.com/watch?v=Fn6g... (via @elizabethtasker.bsky.social ). For those keeping track: This is the only spacecraft headed to Mars during the current launch window.

Rainy couple of days in #Granada, but then the sun comes out to reveal the season's first snow on the #SierraNevada!

Luckily I have a pair of 3D glasses for just such cases! 🕶️

Very interesting idea. I kinda hate the idea of reading something on a timer with other people during a meeting, but I do like the idea of digesting something written down and then discussing it.

in many ways [the pressure] here should be zero, but it should not be zero #ThingsActualScientistsSay

Forgot to repost this yesterday, but yes, the attack on Weathertop happens on my birthday!

My latest cartoon for @newscientist.com

"In addition to the General Conditions of Participation... proposals need to: ... Not violate fundamental laws of physics ..." No perpetual motion machines? You got it boss!

Some impressive artwork here. Gonna have to up our game for my next ISSI Team! 🙂

I hinted that there would be more images from the Juice flyby, so here is the timelapse of the full event! It's always amazing to get these views of our fragile Blue Marble from the spacecraft we send out to explore the solar system! 🔭🧪 #planetsci

On my birthday! A good omen? 🤞

A successful Earth flyby improves Juice’s course to Jupiter Earlier today, Juice flew just 8640 km above the Indian Ocean and snapped these images with its onboard monitoring cameras. 1️⃣Africa, by Juice monitoring camera 2️⃣Madagascar, by Juice NavCam 3️⃣Moon, by Juice NavCam 🔭 🧪 #planetsci

a collaborator told me about a useful statistical measure and I went to look it up on wikipedia to find it was "prompted by the problem of identifying the similarities of skulls based on measurements"... oh...umm... right...!

Fascinating thread on comparative planetology for rocky #planets, the results of an interesting sounding @issibern.ch meeting!

Yay (old) Hampshire! Also, New Zealand is biiiiig! Also, New Jersey... huh! Never thought about that

these are cliffs on a comet that we landed a spacecraft on btw

"Slurm keeps killing my children" #ThingsActualScientistsSay

#Earthquake! Well I missed the big ones here in #Granada over summer, but I've definitely felt one now!

Glorious, as ever
