Explanation for Formation of Abundant Features on Europa bodes well for search for Extraterrestrial Life

This artist’s conception shows how double ridges on the surface of Jupiter’s moon Europa may form over shallow, refreezing water pockets within the ice shell. This mechanism is based on the study of an analogous double ridge feature found on Earth’s Greenland Ice Sheet. (Image credit: Justice Blaine Wainwright)

Ice-penetrating radar data from Greenland suggests that shallow water pockets may be common within Europa’s ice shell, increasing the potential habitability of the Jovian moon’s ice shell.

Europa is a prime candidate for life in our solar system, and its deep saltwater ocean has captivated scientists for decades. But it’s enclosed by an icy shell that could be miles to tens of miles thick, making sampling it a daunting prospect...
