In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.

On the masses and motions of mini-moons: Pandora's not a "shepherd," but Prometheus still is

As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.

Eight of the last 14 sols have seen drives ranging in length from 30 to 104 meters, racking up a total of more than half a kilometer. They are now occasionally working a shortened planning timeline that allows them to squeeze more drive sols into Curiosity's schedule.
