New ground-based images of Uranus show more finely detailed structure than any photos I have ever seen.
A summary of just one talk from the Division for Planetary Sciences meeting, by Lindy Elkins-Tanton, which provided a neat explanation for how asteroids can be melted and layered on the inside yet have a primitive-looking exterior.
During my visit to D.C. to discuss Planetary Exploration funding with key people on the Hill, members of the Planetary Society gathered at George Washington University to hear the latest science results from NASA's Curiosity and Opportunity rovers.
In the first full day of the annual meeting of the Division of Planetary Sciences of the American Astronomical Society, I listened to scientific sessions on icy worlds and on an exoplanet in a four-star system.
A Curiosity press briefing yesterday gave some of the first results from ChemCam and APXS on the rock "Jake Matijevic." It was a little too much petrology for most people; I do my best to explain.

Long-runout landslides (sturzstroms) are found across the Solar System. They have been observed primarily on Earth and Mars, but also on Venus, and Jupiter’s moons Io and Callisto. I have just published a paper about sturzstroms on Iapetus.
I'm hosting this week's Cosmoquest Science Hour, and plan to take viewers on a virtual tour of those mountains on Curiosity's horizon, and show you where Curiosity is likely to go. Join me and Fraser Cain here at 1600 PDT / 2300 UTC Wednesday.

NASA's Radiation Belt Storm Probes will shed new light on the Van Allen Radiation Belts, a dangerous region of space in our planet's backyard.
Some notes from this morning's Curiosity press briefing: the rover will be driving to "Glenelg" to investigate the "high thermal inertia unit." I explain what that means, with psychedelic Odyssey THEMIS images of the landing site.
A new monthly series of Southern California Public Radio events begins with a look at how intelligent machines and virtual humans will change what it means to be a real human. Attend or watch the live webcast tonight, Thursday, August 16.

I'll be guest hosting this week's Cosmoquest Science Hangout on Wednesday, August 1. The show starts at 2300 UTC, and my special guest is Mihály Horányi.
Pluto is now known to have at least five moons (Charon, Nix, Hydra, P4, and the newly discovered P5), and its burgeoning population might pose a risk to New Horizons during its flyby, three years from now.
