A team of researchers led by Cornell's Radwan Tajeddine examined Cassini data and found evidence that the active south polar region of Enceladus - the fractured terrain seen here at bottom - may have originally been closer to the icy moon's equator.
Millions of years ago, basins were once strung along the equator and poles of Saturn's icy moon Enceladus (left). After the "true polar wander" event, the moon flipped by 55 degrees into its current state (right).
