I think if you polled most space fans about their favorite moons of Jupiter, Ganymede would come in a consistent third behind Europa and Io. It's just not fair.

I love posting animations of Cassini images that I compose from frames grabbed from the mission's raw images website, but they are shoddy compared to the versions that eventually come out from the mission's imaging team.

Miranda is the one moon of Uranus for which we have very good images from Voyager 2, and that was a stroke of luck, because low-resolution shots of all of Uranus' moons would have told us that it was, geologically speaking, the most dramatic of the five biggest ones.

Iapetus! I'm always interested in Cassini images, but five years ago this month I was refreshing the Cassini raw images website several times a day, eagerly anticipating the mission's first good encounter with Iapetus.

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.

Those of you who follow me on Twitter know that I've been fiddling with images from the Mars Webcam, more officially known as the Mars Express Visual Monitoring Camera (VMC), for the last couple of weeks.

We have three orbiters and two rovers currently exploring Mars, each of which returns breathtaking photos on a daily basis.

I've gotten this question about once a week since Spirit got stuck, but yesterday, two different readers asked the same question within an hour of each other, so I figured it was time for a blog entry.

The ever-vigilant Doug Ellison just posted this animation, which really actually does show a teeny tiny bit of motion in the right front wheel. If you don't notice any motion, look closer.

The Moon is the most familiar of the objects in the heavens.

It was worth my while to get up at 5:15 my time this morning -- I saw a flawless launch of a Delta II from Vandenberg Air Force Base, carrying the Wide-field Infrared Survey Explorer (WISE) into orbit.

If you don't think Pluto gets enough respect, just imagine what it's like to be a satellite of an asteroid.
