Astronomers from the Leiden Observatory in Netherlands and Rochester University in the United States discovered a planet encircled by a ring system more than 200 times the diameter of Saturn’s. With more than 30 rings, it’s the first system of its kind to be discovered outside our solar system, and it may be churning out more moons and protoplanets.
