Cassini spies mysterious object named ’Peggy’ at edge of Saturn’s rings

Nasa’s Cassini spacecraft has spotted an object located right at the edge of Saturn’s A ring that is confounding scientists. Its name? Peggy.

This strange something was spotted by accident on 15 April when Cassini’s cameras were aimed at a tiny moon named Prometheus that orbits just inside another of Saturn’s rings. A member of the mission’s imaging team, astronomer Carl Murray of Queen Mary University of London, noticed an odd kink at the A ring’s edge that jutted outward.

"I’d not seen anything like this personally in the A ring," he said during a talk today here at the 2013 American Geophysical Union conference.

Because he was analysing the images on 19 April, the same day as his mother-in-law’s 80th birthday, Murray named the mystery object after her. Peggy (the object) appears to be about 1 kilometer in diameter, much too small to be a moon or even moonlet, which are generally at least 10 times bigger. Cassini’s cameras can only see down to about 10 km, so Peggy is only known by the interference it causes.

"What he sees is a disturbance in the rings," said physicist Matthew Headman from the University of Idaho, also a member of Cassini’s imaging team but who was not involved in Murray’s work.

Nobody knows exactly what Peggy is.
