Here's a newly announced contest that is right up my alley and, I hope, of interest to regular readers of this blog. ESA has just announced "Hubble's Hidden Treasures," a contest to encourage what I've been trying to get people to do for years: trawl through the Hubble archives to find unappreciated tresures of photos and make them pretty for public consumption. They have two categories, one for newbies (who can use image processing tools provided on ESA's website) and one for more serious amateurs (who can use other software).
Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.

In this week's Snapshots from Space video, I talk about the Voyager 1 images of Jupiter -- how many there are (tens of thousands), and what a challenge they represent for image processors. But, I promise, the effort is worth it. Here's just one example: it's a color, crescent view of Jupiter, taken by Voyager 1 as it departed.

Clearly, this is Saturn, and its rings, and if you look closer you can see a tiny circle, on top of the rings, which is Mimas, and two stars in the background. It should look weird to you that while the rings are bright, Mimas is a black dot. What is happening here? Nearly everything in this picture is lit by light that has not arrived directly from the Sun.

The second episode of Emily Lakdawalla's new video series reveals the gigantic library of solar system images captured by NASA spacecraft, and explains why we've seen so few of them. Emily says they're all online, waiting for space geeks to turn them into gold.

It took Don Davis many hours of meticulous labor to assemble this beautiful postcard from Mars.

�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.
At last: Rosetta's Mars flyby photos have been released!

Cassini flew close by Dione on December 12 and, as usual, the close pass provided opportunities for lots of dramatic photos, not just of Dione, but of other moons wandering by in the background.

In celebration of the 40th anniversary of Mariner 9's November 13, 1971 arrival at Mars, Daniel Macháček has produced a morphed animation of the images that Mars' first orbiter took while approaching the planet.

A presentation providing a correctly scaled, reasonably correctly colored view of the largest bodies in the solar system is made available for use by teachers, professors, and informal educators.

Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.

I'm nearly two weeks late getting to this news but better late than never, right? There was a press briefing from the Dawn mission at the Geological Society of America (GSA) meeting on October 12.

Cassini has completed two very close flybys of Enceladus in less than three weeks, one of them just this morning, and the images from that encounter have already arrived on Earth.

Since Cassini currently orbits Saturn within the plane of Saturn's rings, it has lots of chances to catch two or more moons in the same photo. One such "mutual event" happened on September 17, featuring four moons: Titan, Dione, Pan, and Pandora.
