Peggy, Saturn’s little moon that could, isn’t dead yet

Backstreet’s back, alright! I mean Peggy, Peggy’s back.

Saturn’s newest moon has had rough go in her first years—for a year scientists believed Peggy had died before she could really live.

In April of 2013 scientists first noticed the 1.2 miles wide little moon near Saturn’s A ring and she became known as Peggy, according to National Geographic. Astronomer Carl Murray described Peggy as an “extended object, somewhere near the edge of the ring” in an interview with National Geographic, but in laymen’s terms she looked like a lone bright spot on the last grove of a glowing vinyl record. It wasn’t long before Peggy seemingly vanished and the scientific community feared she’d been busted apart. Her fate remained unclear until the Cassini-Huygens space mission saw her again in 2015 and 2016 footage.

Peggy has a new dent in her from an unknown collision, but she’s still orbiting A ring just with a portion of her trailing along beside her, Peggy B.
