Very exciting new result we were able to help a bit with. Among many other things it is possibly the first geophysical detection of high pressure ices, and the first real world observation of the cenotectic.

What a year! Very grateful for the recognition of all the hard work accomplished by our team at UW and abroad over the last few years by the IAPWS. More exciting things to come very soon!

Imaging Ganyemede’s Interior using Tides? 🛰️ Here, we propose measuring Ganymede’s response to tidal intercations with Jupiter using JUICE gravity data. In doing so, we can (maybe) tease out shell thickness variations, which would indicate a convecting ocean. Read more at: doi.org/10.1029/2025...

The Moon's nearside mantle is a giant volcano? 🌋 In this study, we infer a 100-200 C temperature anomaly in the Moon's nearside mantle. This anomaly suggests that geologic activity which formed the mare 3-4 billion years ago is still active today. nature.com/articles/s41...

@uwess.bsky.social's @bjour.bsky.social is uncovering how the "cenotectic" could reshape our search for life on icy moons. Journaux and @tamu.bsky.social's Matt Powell-Palm dive into extreme environments, and what they reveal about more than just planetary science. ess.uw.edu/2025/03/unlo...

🚀 As NASA’s Europa Clipper embarks on its 5.5-year journey to Europa, a new study in Nature Communications led by UW planetary scientist @bjour.bsky.social reveals groundbreaking research that could revolutionize the search for habitability in our solar system and beyond. Read the full story👇

Undergrads I mentor are seeking PhD programs. Grad students I work with are looking for postdoc positions. Postdocs like me are hoping to become faculty. Without federal support, many of these dreams will evaporate. It's alarming and depressing to watch so many doors close around us.

We are experiencing an assault on science unparalleled by anything I’ve seen in my life. It’s not one issue or another anymore, the entire institution is under attack by the most powerful individuals in the country. This Friday, where will you be? standupforscience2025.org

For anyone disappointed by 2024 YR4's disappearing threat please remember that even at its peak of ~3% chance it still had a negative rating on the Palermo scale. 1/

Anyway, "GenAI can inhibit critical engagement with work and can potentially lead to long-term overreliance on the tool and diminished skill for independent problem-solving" bsky.app/profile/keta...

To understand why the probability of impact was increasing in recent days and is likely to drop to 0 in the next few days/weeks it is important to realize that it was mostly driven by the size of the 1sigma uncertainty which diminished with better observations while earth was still inside it.

New results from several of my colleagues in the Planetary Interiors and Geophysics group at JPL (which we lovingly refer to as PIGS).

This video by @hankgreen.bsky.social covers why the Galilean moons are so amazing. I love Pluto too, but #Io, #Europa, #Ganymede and #Callisto are top tier Solar System objects. 🧪🔭 #Astronomy #Science #Geology #PlanetaryScience #Space Shoutout to the Europa Clipper: science.nasa.gov/mission/euro...

Something important to understand about how science is funded in the US

What's it like presenting your research to 25,000 scientists? ESS PhD student Haskelle White-Gianella shares an insider's view on her first AGU conference, what it's like giving a talk to the AGU scientific community, and making connections for her career and future as a planetary scientist! 🪐🌎

Inkcap is not a bad one, but I wish I was on the Hydnellum peckii server… 🍄‍🟫🦷

Elena & Topher now have a gofundme: gofund.me/153d27e6. Please help if you can!

Elena and Topher are amazing people and old friends from Seattle before they moved to California. If you can help, consider donating, they lost their house yesterday. What an horrible tragedy for so many folks.

The cenotectic concept offers a new framework for assessing liquid stability on icy moons, aiding the search for life in extreme environments like Jupiter's Europa. doi.org/g8wf9t

Incredibly excited to annonce the publication of our new experimental thermodynamic work at high pressures with the definition of a novel thermodynamic invariant point: The Cenotectic (κ) nature.com/articles/s41...

How big is Dragonfly? Bigger than most think! (At least me). Was able to hold one of the test blades, and visualize the full scale virtual model. It's close to the size of a mini-van / SUV. What an amazing mission!

Amazing new images of the moon Io have come down from the Juno spacecraft! This one shows the volcanic moon of Jupiter from only 2,800 kilometers away, which is the closest look we’ve gotten of Io since over 20 years ago. Check out all those volcanoes!!!! NASA/JPL-Caltech/SwRI/MSSS/Kevin M. Gill
