"It's perhaps one of the best places beyond Earth to look for life in our solar system," Cynthia Phillips, a NASA planetary geologist and project staff scientist for the space agency's Europa Clipper mission, told Mashable.

"This region sports ice rafts that look like those at Earth's poles, where large chunks of ice break away and float freely on the ocean," the agency wrote.

"Much of the region bears the reddish/brownish discoloration seen here " the same as seen along many of Europa's fractures. Scientists believe this material may contain clues about the composition of an ocean beneath the icy surface, if it is proven to exist."
