The heat gave Europe Jupiter’s icy moon. That may be good news for the pursuit of life.

Jupiter’s icy moon Europe Scientists say they experienced enough heat to produce a layered inland and underground ocean. The finding could help researchers learn about the potential for life on other worlds.

Mohit Melwani Daswani, a planetary scientist at NASA’s Jet Propulsion Laboratory in California, led a team that analyzed the data collected by the Galileo mission. Starting in the mid-1990s, Galileo studied Jupiter and its moons for about eight years and discovered that a global ocean of liquid water is likely to exist below Europe’s icy surface.
