Planetary Society Advent Calendar for December 31: Uranus

Emily Lakdawalla • December 31, 2009

Did you think I was going to skip Uranus? How could I?

Planetary Society Advent Calendar for December 30: Tempel 1

Emily Lakdawalla • December 30, 2009

Looking over the list of planets, moons, and smaller bodies I posted so far, I realized I didn't have an image of a comet yet.

Planetary Society Advent Calendar for December 29: Rhea

Emily Lakdawalla • December 29, 2009

Rhea? You might be asking. Rhea? When Saturn has so many more interesting moons? Hear me out.

Planetary Society Advent Calendar for December 27: Prometheus (hot off the presses!)

Emily Lakdawalla • December 27, 2009

This one is fresh from the spacecraft! The data were captured yesterday, December 26, by Cassini during its best yet imaging encounter with the small ringmoon Prometheus, and showed up on the Cassini raw images website today.

Planetary Society Advent Calendar for December 24: Ganymede

Emily Lakdawalla • December 24, 2009

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.

Awesome Cassini mutual event movies

Emily Lakdawalla • December 23, 2009

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.

Planetary Society Advent Calendar for December 22: Venus

Emily Lakdawalla • December 22, 2009

Venus is such a beautiful, brilliant light in the sky. (When it's up; just now Venus is actually near solar conjunction, so we'll have to wait a bit for it to grace the heavens.)

Planetary Society Advent Calendar for December 21: Miranda

Emily Lakdawalla • December 21, 2009

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.

Planetary Society Advent Calendar for December 18: Neptune

Emily Lakdawalla • December 18, 2009

Here's Neptune, but not quite like you've ever seen it before.

Planetary Society Advent Calendar for December 16: Mimas

Emily Lakdawalla • December 16, 2009

Mimas is the anti-Enceladus.
