@bowlerhatscience.org on the recent paper on Neptune's moon Nereid by Belyakov @import-astrory.bsky.social @plutokiller.com & co. www.science.org/doi/10.1126/...

1) Open this image up 2) Find the small, blue feature in the very middle Congratulations, you've spotted the Perseverance rover on Mars, photographed from orbit! 3) Trace the rover tracks as they wend their way across the surface

There’s a new proposed rule that can cancel a grant at any time and all new grants have to be approved by political appointees. Submit a comment here and let them know how catastrophic this would be for US Science. www.regulations.gov/document/OMB...

Some light Friday afternoon reading - @caltechipac.bsky.social wrote a nice piece on Scaling K2, the K2 exoplanet demographics collab that I lead, and that @kevinkhu.bsky.social wrote both the first and latest papers for! (Wherein I confess to the most unoriginal astronomer hobby.)

So thrilled to see this out today and proud to be part of it! 🎉JWST spectroscopy + N-body sims pointing to Nereid as the last survivor of Neptune's original moon system. Huge congrats to @matt-belyakov.bsky.social who led this work! MOONPOCALYPSE WAS REAL 🪐🔱💥🔭

Just before finishing my PhD and leaving Caltech in April, I had the opportunity to give this year’s Everhart Lecture. The recording is now online! If you’re interested, you can watch it here: www.youtube.com/watch?v=61bu...

Do you know of an undergrad who would be a good fit for icy moons or geophysics research? If so, encourage them to apply here: stemgateway.nasa.gov/s/course-off...

"You’re punching a generation-size hole, maybe a multigenerational hole, in the scientific and technical workforce. You don’t just Cryovac these people and pull them out when the money comes back. People are going to move on.” www.scientificamerican.com/article/prop...

Briefly wandered over to The Other Place to gauge the response to the NASA budget devastation to encounter a bunch of gleeful 'we spend too much money, so this is great.' TO BE, ONCE AGAIN, PERFECTLY CLEAR, THE BUDGET REQUEST MOVES ALL THIS MONEY TO DEFENSE. IT SPENDS IT. NO MONEY IS SAVED.
