This is a major southern electrical storm on Saturn imaged a few months ago. The left image is close to what human explorers would see if Cassini were big enough to house people on its mission to the sixth planet. On the right, the 939 nanometer infrared band is added to visible color wavelengths to highlight some storm details.
NASA has an audio version of electrical activity on Saturn: http://ciclops.org/view.php?id=4962
I mention this in part because Henry Cate at Why Homeschool? is hosting the first anniversary carnival of space, the internet event he began a year ago. A bunch of interesting stories to browse, picking up on the theme of science fiction on tv.
