Saturn's Rave
Looks like there's a rave on Saturn. The (top) ultraviolet image of the southern polar region of Saturn, with its rave-like aurora, was taken on January 28, 2004 by the Hubble Space Telescope's Imaging Spectrograph.
On Earth, auroral storms may develop in as little as ten minutes and last for no more than a few years. On Saturn, however, the rave lives on - it can last for days.
Saturn's auroral storms are primarily caused by the pressure of solar wind, a stream of charged particles from the Sun. When the aurora becomes brighter and more powerful, the ring shrinks in diameter.
Unfortunately, the ultraviolet representation is a little misleading - it does not properly represent what you would see if you were flying around up there. The above drawings are an artist's conception what one might see, but we can be fairly confident that if the ultraviolet was excited that the visible spectra would be excited as well.

Voyager Golden Record
Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2-a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record-a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.
The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University, et. al. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals. To this they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages, and printed messages from President Carter and U.N. Secretary General Waldheim. Each record is encased in a protective aluminum jacket, together with a cartridge and a needle. Instructions, in symbolic language, explain the origin of the spacecraft and indicate how the record is to be played. The 115 images are encoded in analog form. The remainder of the record is in audio, designed to be played at 16-2/3 revolutions per minute. It contains the spoken greetings, beginning with Akkadian, which was spoken in Sumer about six thousand years ago, and ending with Wu, a modern Chinese dialect. Following the section on the sounds of Earth, there is an eclectic 90-minute selection of music, including both Eastern and Western classics and a variety of ethnic music. Once the Voyager spacecraft leave the solar system (by 1990, both will be beyond the orbit of Pluto), they will find themselves in empty space. It will be forty thousand years before they make a close approach to any other planetary system. As Carl Sagan has noted, "The spacecraft will be encountered and the record played only if there are advanced spacefaring civilizations in interstellar space. But the launching of this bottle into the cosmic ocean says something very hopeful about life on this planet."
The definitive work about the Voyager record is "Murmurs of Earth" by Executive Director, Carl Sagan, Technical Director, Frank Drake, Creative Director, Ann Druyan, Producer, Timothy Ferris, Designer, Jon Lomberg, and Greetings Organizer, Linda Salzman. Basically, this book is the story behind the creation of the record, and includes a full list of everything on the record. "Murmurs of Earth", originally published in 1978, was reissued in 1992 by Warner News Media with a CD-ROM that replicates the Voyager record. Unfortunately, this book is now out of print, but it is worth the effort to try and find a used copy or browse through a library copy.

The answers to some of the universe's greatest mysteries are being beamed through the night sky in light we can't see with human eyes…but it won't be invisible to us forever. "Infrared: Beyond the Visible" explores the wonder of infrared astronomy and the promise of the upcoming Webb Space Telescope. Get a sense of the sights Webb will capture, with its Hubble-sharp vision and ability to reach into the farthest depths of space and time.
