You've maybe heard of ocean planets 🌊🪐 but what about *electric magma* ocean planets?! 🔥⚡🌋 For our next #RockyWorldsDiscussion on Thu 5 March @ 14:00 UTC, Miki Nakajima will present exciting simulations on magma ocean dynamos in Earth and super-Earths More: www.rockyworlds.org/event-detail... 🧪🔭

Would you dare to stand up against the wrath of a star?! Brave little Venus does... and still has an atmosphere! ☀️💨🪐🧲 Next #RockyWorldsDiscussion on Thu 5 Feb @ 14:00 UTC features Moa Persson on "Venus: Defying the Solar Wind Without a Magnetic Shield" More: www.rockyworlds.org/event-detail... 🧪🔭

A HUGE thank you to all attendees of the #RockyWorlds4 conference in Groningen! We had an absolutely incredible time talking astronomy, geoscience, biology, and so much more 🚀🌋🌱🪐✨🔭🧪 Catch the recorded talks on www.youtube.com/@rockyworlds And see you in Berlin in 2028! berlin2028.rockyworlds.org

Had a great time at #RockyWorlds4 this week - presenting my PhD work on magnetic field generation in planetesimals 🧲 and learning lots about magma oceans 🔥ready for my post doc project. Thanks to everyone for such great discussions and @rockyworlds.bsky.social for organising a fantastic meeting!

🌍 Astronomers from all over the world are coming to Groningen for the #RockyWorlds4 conference. 'We would like to broaden the ideas about what a rocky planet could be made up of,' says Inga Kamp, astrophysicist @rug.nl. Curious? Read more 👇 🔗 www.rug.nl/fse/news/mat... 🧪 #SciComm
