New unified model of equatorial winds on giant planets helps to explain some of the zonal wind observations 🔭 I and my colleagues have made for Neptune and Uranus over the past few decades - www.science.org/doi/10.1126/...

From gas to ice giants: A unified mechanism for equatorial jets

A bifurcation in equatorial jet formation can explain the differences between the gas and ice giants.

LPSC is already in a state that's unsafe for large portions of the community, and now the conference itself is erasing traces of marginalized groups and efforts to make the field better. We could let them know how much we dislike those choices! We could demand our scientific organizations help us!

The effort put into understanding 3I/Atlas has been spectacular, imaginative, professional and well-organized. Planetary scientists don't need Avi Loeb put in charge of an international directorate to tell them how to do their jobs.

Well I propose that the United Nations name ME the Director General of Dark Energy Studies and gift ME 500 hours of over-subscribed telescope time a year, if this is how we're doing things now.

This is complete and utter pompous bullshit. It's telling that of the people proposing it wants to anoint themselves director general when every one of his claims of having discovered technosignature interstellar objects has been debunked by the planetary community. arxiv.org/pdf/2510.01405

If anyone from the UN wants to talk, here’s a nice summary. The astronomy community does NOT endorse this proposal, just take it from one of THE EXPERTS on ISOs with Rubin. Meg (and many others) has helped the community plan for +10yrs for these kinds of studies.

I'll for global coordination for ISO follow-up, but it's telling that no one who's actually coordinating follow-up was actually asked to participate in this proposal or thought of to be even suggested as names on committees in this proposal

guy from Mars

Digital illustration showing various doodles of a guy with pale skin, ginger hair, and yellow eyes. In one of the doodles he's shown eating a sandwich. Next to the sandwich is some text reading: "Sandwich featuring GMO-derived bread, cheese derived from cultured milk, and cultured GMO ham."

In the background is a coloured heightmap of the western region of Hellas Planitia, with the lowest sections coloured blue to represent water. Surrounding the water is a haze of green, pressumably representing flora coverage.

A few hours ago, Comet 3I/ATLAS passed about 28 million km from Mars.

This was the best opportunity we'll have to image the interstellar visitor from spacecraft.

When those data are available, I'll share them!

I really have not been posting art for a long time, so I figured I should draw and post something. Here's a human girl.

#art

The image is a sketch of a human girl. Their hair is done into a short twin tail. They wear a jacket over a casual T-shirt, and a miniskirt. They wore a belt over their jacket.

I understand that a big aspect of it is that M-dwarfs also live for a lot longer, so there is way more time for us to emerge around them than around G-dwarf stars.

A lovely story about Dr Jane Goodall's career & legacy, from Rachel Fieldhouse & Mohana Basu, in @nature.com www.nature.com/articles/d41.... Includes some comments from me about how researchers _can also_ be advocates and science communicators, and still be taken seriously (I hope)!

Vale, Jane.

This photo from the Perseverance rover captured in early March, may be my favorite Mars image from this year.

It shows Mars' smaller moon Deimos over the hills of the Nili Planum region in the dark skies before dawn. 🔭

A picture of Mars taken during astronomical twilight (the sun was 13° below the horizon). It shows a dimly lit reddish landscape with some hills at the horizon. Deimos, Mars' smaller moon shines with a small halo in the pale sky above.

AI has gotten much better at a lot of things, but my mental model that it should only be used for tasks you would give an overeager and overconfident intern remains pretty solid.

I am often impressed by the work it does, but you have to double check everything yourself if it needs to be right.
