M64: The Sleeping Beauty Galaxy - March 22nd, 1997.

"The Sleeping Beauty galaxy may appear peaceful at first sight, but it is actually tossing and turning. In an unexpected twist, observations have shown that the center of this photogenic galaxy is rotating in the opposite direction than the outer regions! Stranger still - there is a middle region where the stars rotate in the opposite direction from the surrounding dust and gas. The fascinating internal motions of M64, also catalogued as NGC 4826, are thought to be the result of a collision between a small galaxy and a large galaxy - where the resultant mix has not yet settled down."

This video is made from 47 images captured by NASA's Cassini spacecraft during a flyby of Saturn's moon Hyperion on May 31, 2015. Changing spectral filters result in slightly different exposures and contrasts. (Images were sourced through @setiinstitute's OPUS3 online server.

The HR 8799 system harbors four super-Jupiters orbiting with periods that range from decades to centuries. We're currently monitoring this system to understand if and how this system is dynamically stable. This footage consists of 7 images of HR 8799 taken with the Keck Telescope over 7 years. Video made by Jason Wang, data reduced by Christian Marois, and orbits were fit by Quinn Konopacky. Bruce Macintosh, Travis Barman, and Ben Zuckerman assisted in the observations.
