New research has revealed the sliding side-by-side motion along distinctive "tiger stripes" on Saturn's moon Enceladus is linked to jets of ice crystals that erupt from its icy shell. The findings could help determine the characteristics of this icy moon of Saturn's subsurface ocean and, thus, if Enceladus is favorable to life.
The tiger stripes of Enceladus consist of four parallel line fractures in the moon's south pole that were first observed by NASA's Cassini spacecraft in 2005. "Cryovolcanism" in this region blasts out ice crystals believed to originate from Enceladus' buried ocean from these fractures, causing a broad plume of material to gather over the south pole of the Saturnian moon.
