Once again my email autocorrects “dunite” to “unite,” causing me to send emails where it seems like I’m trying to unionize the Moon
Happy pride month! I worked with some LA-based scientists and engineers, and we have a kickstarter for space pride t-shirts! Consider backing! 🛰️🏳️⚧️🚀🏳️🌈🪐 www.kickstarter.com/projects/spa...
The public meltdown happening between the world’s richest man 🙄 and the President of the United States 🙄🙄 once again begs the age-old question: are men simply too emotional to be in positions of power?
this is a day for those of us who have spent the last six months terminally online. this is for us and honestly, we deserve it.
Pride Month question: are any of the planets straight? Discuss.
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...
This is one of the highest-resolution images ever to show "coronal rain"—cooler, ionised gas in the Sun's corona that falls back down, following curved magnetic field lines as it does so. This image was taken in the hydrogen alpha spectral line; I inverted the image such that brighter = hotter.
it's nice of SpaceX to demonstrate a new failure mode for starship every launch
Hydrogen escape contributed to Mars' progressive aridity, but current H-loss rates cannot explain inferred past water abundances. A 3D model shows that during periods of increased axis tilt H-loss rates were up to 10x higher than at present.

Hydrogen escape has contributed to Mars’s progressive aridity, but current hydrogen loss rates cannot explain inferred past water abundances. A three-dimensional model shows that during periods of increased axis tilt, hydrogen loss rates were up to ten times higher than present values.

Thermal asymmetry in the Moon's mantle inferred from monthly tidal response
We analysed the PM and XM data from the GRAIL mission. The PM phase started on 1 March 2012 and ended on 29 May 2012 (that is, 89 days) with the average altitude of roughly 55 km (ref. 5). The...

This is insane, and sabotages the future of US science—and it’s so easy to see why… AI, quantum, etc., all started as niche research 10, 20, 50 years ago. They’re “trendy” science of national importance today because of decades of investments in broad, fundamental research. (🧵1/3)

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...

Mark Panning@markpanning.seismology.space · last yr.Cool new paper out. Ryan Park and Alex Berne (with the help of a lot of other co-authors including a tiny role from me) pushed the GRAIL lunar gravity data further than before, notably updating the estimate of the k3 Love number. www.jpl.nasa.gov/news/nasa-st...
