CAPE CANAVERAL, Fla. (AP) — New research suggests that Saturn’s rings may be older than they look — possibly as old as the planet.
Instead of being a youthful 400 million years old as commonly thought, the icy, shimmering rings could be around 4.5 billion years old just like Saturn, a Japanese-led team reported Monday.
