A newly discovered alien planet's ring system puts Saturn's collection to shame. The exoplanet, called J1407b, could even harbor at least one Earth or Mars-sized moon, judging by a large gap in the rings, scientists have found. This discovery marks the first time researchers have found this kind of ring system outside of the solar system. "This planet is much larger than Jupiter or Saturn, and its ring system is roughly 200 times larger than Saturn's rings are today," co-author of a new study about the rings Eric Mamajek, of the University of Rochester in New York, said in a statement. "You could think of it as kind of a super-Saturn." via Space.com.
