Astro Brief: Saturn's Rings

NASA/JPL-Caltech/Space Science Institute

Are Saturn's Rings here to stay?

Discovered in 1610 by Galileo, Saturn's rings have been viewed for hundreds of years by astronomers. These rings, composed mostly of water-ice particles, range greatly in size and are thought to be formed by passing asteroids ripped apart by tidal forces. In 2004, NASA's Cassini spacecraft arrived at Saturn to study its rings after a 7 year voyage, studying the gas giant and its rings until 2017. Join us this week as Mike explores the rings of Saturn and their fate.
