Saturn's aurora, even better than before

The Cassini imaging team have posted their own processed and captioned version of the Saturn's aurora movie that I posted a preview of about six weeks ago, and it was worth the wait.

Cassini's Enceladus encounter, with bonus Tethys

Raw images from Cassini's close pass by Enceladus today started appearing on the JPL raw images website, and some less-compressed versions of a few of them showed up on the CICLOPS website.

What "phase angle" means

As is probably obvious by now, I love playing with spacecraft image data. I am always looking for excuses to dive into space image archives to unearth images of stuff in space that haven't really been seen by very many people before.

Saturn shadows shift with the seasons

So many goodies on the Cassini raw images website lately! I am especially excited when Cassini takes photos through red, green, and blue filters so that it's possible to create views that look roughly like what you'd see with your own eyes.
