We Now Understand Why Enceladus has ‘Tiger Stripe’ Cracks at its Southern Pole
One of the biggest surprises of the 13-year Cassini mission came in Enceladus, a tiny moon with active geysers at its south pole.

Instead, this little moon is one of the most geologically dynamic objects in the Solar System.
