Just because you live in an urban area with skyglow doesn't mean you can't have fun with astrophotography. How to capture the planets, constellations and the ISS.

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.

Some time in the last few days, the Dawn team made public the first preliminary version of the first release of their data from the Vesta phase of their mission.

How does the LRO lunar map compare with the new Chinese product from Chang'e 2?

It's amateur astronomers, not professionals, who are shouldering the burden of constant monitoring of the weather on Jupiter and Saturn. What's going on these days in the outer solar system?

Here's an awesome picture to start off the week. The data came from Cassini's flyby of Enceladus on January 31, 2011; it was part of Cassini's January 2012 data release.

On February 24, 2007, the Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released two photos from the main science camera, OSIRIS.

Whether you heard the show or not, you'll be fascinated by Emily's great presentation. It also proves she is not part of the great conspiracy that is hiding evidence of alien bases on the moons of Saturn!

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.

A few fortunate (and forward-thinking) skywatchers looked upward in the hours after Curiosity's launch and were able to see the spacecraft leaving Earth.

Last week JPL released two animations of asteroid 2005 YU55 made from the radar data acquired by Goldstone's 70-meter radio dish.

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.

This is a repost of an article I wrote in April 2010; I thought it'd be useful reading for those of you interested in today's near-Earth flyby of asteroid 2005 YU55.

The Dawn mission to Vesta continues to release an image every day, and recently they have been releasing lots of color images. I like color pictures for aesthetic reasons, but color is actually a very important property of planetary surfaces.

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.

It's been a week of very heavy science on this blog, so I thought it'd be nice to go into the weekend with a post in which a breathtaking picture speaks for itself, without needing my thousands of words.
