This is an artist's concept of a plume of water vapor thought to be ejected off of the frigid, icy surface of the Jovian moon Europa, located 500 million miles from the sun.

An image of Europa released by the Jet Propulsion Laboratory in Pasadena, Calif., in 1996 by the Galileo spacecraft. NASA says a new probe dedicated to studying the Jovian moon, is going into the development phase.
The mosaic was constructed from individual images obtained by the Solid State Imaging (SSI) system on NASA's Galileo spacecraft during six flybys of Europa between 1996 and 1999.
