When the Cassini spacecraft finally gets to Saturn next year, it will have some big shoes to fill — its own. The robotic probe has snapped what’s being billed as the best picture ever of Jupiter.

The time-lapse video was created by lining up still photographs shot over a number of hours in January 2001 by the Cassini spacecraft. According to its creator, slight alterations were made so that ...
