A terrific set of Goldstone radar images of a good-sized near-Earth asteroids named 2010 JL33 was posted to the JPL website yesterday. They also posted a movie version but something about these pixelated radar image series absolutely begs for them to be displayed as an old-school animated GIF, so I made one.

Time to open the twentieth door in the advent calendar. Where in the solar system is this diffuse blob and stripy sea?

The Cassini mission announced today the first observation of a specular reflection off of a lake on Titan. A specular reflection is a mirror-like flash, and you only get one when you have a mirror-like surface -- very, very smooth.

Today's science press release out of the Division of Planetary Sciences meeting concerns changes in lakes near Titan's south pole observed during Cassini's mission. In brief, repeat Cassini RADAR observations of the same spots during different Titan flybys turned up places where there appeared to be dark lakes in earlier images and dry lakes in later images.

One of the major results from the Cassini mission last year was the production of a mosaic of images from its RADAR instrument covering Titan's north pole. Titan's north pole has lakes upon lakes, some big, some small, but everywhere you look, there they are.

Lakes have been spotted near the south pole of Titan before, in this image by the ISS team, which was considered compelling but not conclusive at the time.

"What plays in Potsdam stays in Potsdam" - that's how Ralph described a problem I mentioned over at UMSF where I explained I couldn't combine the audio of my talk with the MOV of the slides because you're not allowed to record presentations. It's "law of the stag" for conferences. So, in the spirit of the law, here's an overview of Ralph's excellent overview of Titanian geology as seen by various RADAR passes.
