After just a few short months in the lead, Jupiter has once again ceded the title of 'most known moons' to Saturn.
The discovery of 62 previously unknown satellites has put the ringed planet firmly back in the lead, with a grand total of 145 officially recognized moons. This means Big Jupe, with its paltry 92 known moons, is going to have to pull out some slick moves if it wants to retake the crown.
A Cassini image of five of Saturn's moons, from left to right: Janus, Pandora, Enceladus, Rhea, and Mimas. It's actually fairly challenging locating small moons orbiting Jupiter and Saturn. These two planets are the largest in the Solar System, and they're very bright in the sky, especially from our point of view on Earth, from which they're always in sunlight.
Here's how it works. A set of sequential images is"shifted" at the same rate a moon moves across the sky. Then, these images are stacked, a technique that amplifies signals too faint to be seen in an individual image, and makes them brighter so that scientists can see them.
