Curiosity looked up after dark and captured more cool photos of Mars' moons. They include Phobos and Deimos passing in the night, and Phobos entering Mars' shadow.
Yesterday, the Curiosity mission released the video whose potential I got so excited about a couple of weeks ago: the view, from Curiosity, of Phobos transiting Deimos in the Martian sky. In this post, Mark Lemmon answers a bunch of my questions about why they photograph Phobos and Deimos from rovers.
A large asteroid is passing reasonably close to Earth in a few hours, and astronomers at the great radio telescopes at Goldstone and Arecibo are zapping it. The latest discovery: QE2, like many asteroids, is a binary.
A frequently-asked question last week was: if asteroid 2012 DA14 is coming so close to Earth, why hasn't anyone taken any pictures of it? Now that 2012 DA14 has whizzed past us, we do finally have some radar pictures of it, but they still may not satisfy everyone.
Deep Impact has made the first space-based observations of comet ISON.
A recently launched Earth-observing satellite is using the stars to practice its pointing, and caught a neat animation of Jupiter.
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.
It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.
Curiosity has been shooting photos of the Sun as Phobos and Deimos cross its face, and -- as far as I can tell -- captured sunspots as well.
Even a preliminary, low-resolution, low-frame-rate version of Curiosity's descent imager animation of the arrival on Mars contains almost more awesome than I can stand.

Cassini flew past both Enceladus and Tethys on April 14. Here's a cool animation of its approach to Enceladus' plumes, and a pretty global picture of Tethys.

A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.

On June 30, Dawn stopped thrusting for a full Vestian day -- five hours and 20 minutes -- and just watched the asteroid rotate. But unlike the previous observations, they used all of Dawn's color filters to acquire the best-ever color photos of the lumpy world.
