New Horizons Day 2: Liquids on Pluto's surface?

Posted by Emily Lakdawalla on 2011/09/13 01:27 CDT

Jeff Moore's presentation was cool because of the discussion it stimulated. He considered what exogenic processes might be operating on Pluto's surface. What's an exogenic process? It's something that modifies the shape of the surface from the outside, and doesn't require the body to be geologically active inside.

The Making of Martian Clouds in Motion: Part 1, working with Mars Express HRSC data

Posted by Emily Lakdawalla on 2011/08/22 08:39 CDT

Last Friday I posted an awesome video of Martian clouds in motion. This week I'll tell you how I made it. The how-to is split up into two parts. The first, today, is how to access Mars Express HRSC image data and process it into the individual animation frames, from which you can make an animated GIF.

Watch Saturn's storms spin with VIMS

Posted by Emily Lakdawalla on 2011/04/28 01:15 CDT

A lot of attention has been paid recently to a storm in Saturn's northern hemisphere that is large and bright enough to be visible from Earth, but Saturn's atmosphere actually features lots more swirling storms. They can be hard to see, at least in visible wavelengths.

Pluto's atmosphere changes really fast!

Posted by Emily Lakdawalla on 2011/04/21 10:27 CDT

Pluto's atmosphere has been a subject of fascination for planetary astronomers since -- well, since astronomers first discovered that it had an atmosphere in the early '90s. The interest is partly because it's fascinating that such a distant and cold world is capable of supporting an atmosphere, and partly because the presence of the atmosphere confounds all attempts to measure Pluto's size precisely.

Some recent pictures of Saturn's northern storm

Posted by Emily Lakdawalla on 2011/02/07 04:35 CST

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.
