First Asteroid With Rings Discovered (like how cool is that?!)
Until now it seemed that only giant planets had the gravity to hold on to the billions of bits of orbiting ice and dust that make up a ring, but in a paper published today in Nature, astronomers report the discovery of two icy rings around a small object named Chariklo that orbits between Saturn and Uranus.
The discovery was made possible by observations at many sites in South America, including ESO's La Silla Observatory. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris.
"This probably will be the biggest discovery of my career," says Felipe Braga-Ribas of the National Observatory in Brazil, who led the team that found the rings, and who received his Ph.D. just last year.
