It’s been a long time since anyone paid Uranus a visit. The Uranus system is, however, fascinating, as evidenced by the wealth of topics covered by the diverse group of planetary scientists who gathered to discuss it last week at the Paris Observatory.
Just four months ago I posted about a paper recently published by Leslie Young and coauthors that described three possible scenarios for Pluto's atmosphere. Yesterday, Cathy Olkin, Leslie Young, and coauthors posted a preprint on arXiv that says that only one of those scenarios can be true. And it's a surprising one. The title of their paper says it all: "Pluto's atmosphere does not collapse."

Kat Scanlon tells Planetary Radio that Hawaii and Mars have more in common than you might think.
Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

Notes from Day 5 of the EPSC/DPS meeting: Saturn's storm, Phobos, and Lutetia

Jeff Moore's presentation was cool because of the discussion it stimulated. He considered what exogenic processes might be operating on Pluto's surface. What's an exogenic process? It's something that modifies the shape of the surface from the outside, and doesn't require the body to be geologically active inside.
