Comet PANSTARRS is delighting northern hemisphere viewers right now. But it's also big, bright, and beautiful to the STEREO spacecraft.

This week I'll be talking with NEOWISE principal investigator Amy Mainzer about moving objects that the WISE mission has spotted both inside and outside our solar system.

We don't have any spacecraft at Jupiter right now, which is a pity. Until we do, we have to rely upon Earth-based astronomers to monitor the changing face of the largest planet.

The news from the Curiosity mission today is this: Curiosity has found, at the site called John Klein, a rock that contains evidence for a past environment that would have been suitable for Earth-like microorganisms.

Nearly four decades before Curiosity, we dug into Mars for the first time. The pictures are still amazing.

I use a variety of social networking tools to perform my job, but there's one that's more important and valuable to me than all the rest combined: Twitter. Yesterday afternoon there was a discussion on Twitter that exemplifies its value and fun: are there visible meteors on Titan?

As February turned to March, Opportunity was conducting some of its final science investigations on Matijevic Hill, the MER team was making preparations for the robot field geologist's trek south for the next winter, and the Mars Exploration Rovers mission was checking off another month of exploration.

The Planetary Society President wows his audience with this presentation that is chock full of beautiful space images.

Ever wonder what it would taste like if you could lick the icy surface of Jupiter’s Europa? The answer may be that it would taste a lot like that last mouthful of water that you accidentally drank when you were swimming at the beach on your last vacation.

Last week the Curiosity mission made its first data delivery to the Planetary Data System. The bad news: none of the science camera image data is there yet. The good news: there are lots and lots of other goodies to explore.

JPL's Solar System Dynamics group shows that there is still a possibility that C/2013 A1 (Siding Spring) could hit Mars. But the uncertainty in its position at that time is large -- the closest approach could happen an hour earlier, or an hour later -- so we're a long way from knowing yet whether it will or (more likely) won't impact.

Over the last few days the mission has been working its way through its first major (not life-threatening, just really inconvenient) anomaly: a memory problem in its main computer.

Look past the rings, and Saturn is even stranger--and more breathtaking.
