New high-resolution photos of Jupiter’s icy moon Europa show the surface is covered with something akin to highways rather than craters, and they go on for miles. Europa is believed to be the most likely spot in the solar system to find life outside of Earth. NASA’s Juno mission captured the photos Sept. 29 during a rare flyby that got within about 256 miles of the surface, and scientists admit one photo “of the moon’s heavily fractured icy crust” is puzzling. “The image covers about 93 miles (150 kilometers) by 125 miles (200 kilometers) of Europa’s surface, revealing a region crisscrossed with a network of fine grooves and double ridges (pairs of long parallel lines indicating elevated features in the ice),” NASA says.
