Peek-a-movie!

I was just informed by Twitterer karabaic that the picture of Ganymede going behind Jupiter that I posted yesterday also comes with a very cool animation!

Much higher-resolution versions are available on the HST site.

The astronomers took a series of images of Ganymede as it orbited Jupiter and made an 18 second/540 frame animation of it. Very cool! That's the advantage of observing bright objects: short exposure times means you can take lots of images, and in this case there is motion, too, so a movie becomes totally cool.

Totally awesome.
