You guys like Saturn, right? Here’s a whole gallery of Saturn GIFs, from rings to moons, captured by the Cassini spacecraft. They’re part modern art and part science.
Next to the Voyager twins, I think Cassini might be the best satellite NASA ever launched. Certainly takes the best pictures. Tumblr’s own staceythinx has an iPad app called Cassini HD that features even more photos, plus color, plus science.

This year, NOAA predicts a massive “dead zone” the size of New Jersey will bloom in the Gulf of Mexico.
QUICK TURN ON DANCING WITH THE STARS AND DONT PAY ATTENTION SO THIS WILL GO AWAY.
Eruption of the Tvashtar volcano on Jupiter’s moon Io, photographed by New Horizons, 1 March 2007, during its gravity-assist Jupiter flyby on its way to Pluto. I’ve brightened the pictures so that some detail on the darker part of Io is clearer.
The gif covers about 8 minutes of real time. If you count pixels and look up Io’s diameter, it looks like the plume’s “only” being thrown up to an altitude of 200km or so. But in fact the volcano is in the opposite hemisphere to the one we see here (albeit at a high latitude of about 67 degrees), and the plumes are reaching a height of over 300km.
There is much more detail about this volcano at the Gish Bar Times blog.
