Bats in Space! Cassini Team Sends 'Bats Wishes'

"Happy Halloween"
NASA (October 31, 2009)

"The Cassini team sends 'bats wishes' for a happy, healthy and fun Halloween.

"The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C."

That image is 400 x 300 pixels, half the dimensions of the smallest copy on the NASA website. They've got the picture at Full Size (3600 x 2400), 1600 x 1200, 1024 x 768, and 800 x 600. It'd make pretty good wallpaper - and the NASA website gives instructions for using the image that way, for most sizes of the image.

Enjoy.
