Cassini sent home one last batch of photos from Saturn before plunging to its death Friday and among them was an attempt to record a mysterious object embedded in the planet’s rings, otherwise known as “Peggy.”
Peggy lives along the edge of Saturn and is an anomaly from which researchers have been unable to unearth the source.

The bizarre disturbance was first noticed in 2013 by London researcher Carl Murray, who named it after his mother-in-law after making the discovery on her birthday. And its effects on dust particles and surrounding ice has been recorded ever since.
Murray believes Peggy is a moon forming within the planet’s rings, though researchers have yet to receive a direct image of Peggy’s form.
