Europa is one of Jupiter’s largest moons and is covered in a layer of ice that’s miles thick. Beneath this frozen shell lies a hidden ocean thought to contain more water than found on Earth. But there’s more to this moon than what’s going on below the surface. In 2012, scientists using NASA’s Hubble Space Telescope first observed what appear to be towering columns of water vapor rising from Europa's icy exterior. Now, recent images taken by Hubble provide further evidence of their existence. On three separate occasions in 2014, Hubble spotted what could be 125-mile-high plumes of water vapor gushing from the Jovian moon. Future observations by Hubble and other NASA missions may provide clues as to how often the plumes occur and why they erupt. Watch the video to learn more.

Possible water vapor plumes are circled in these Hubble images of Europa from 2014 (left) and 2012 (right).

Beneath Europa's icy exterior is a subsurface ocean that scientists think is the source of water for the plumes.

The plumes are thought to emerge from vents in Europa's surface. This image provides a close look at the moon's highly fractured terrain.
