This
is an artist's concept of a plume of water vapor thought to be ejected off the
frigid, icy surface of the Jovian moon Europa, located about 500 million miles
(800 million kilometers) from the sun. Spectroscopic measurements from NASA's
Hubble Space Telescope led scientists to calculate that the plume rises to an
altitude of 125 miles (201 kilometers) and then it probably rains frost back
onto the moon's surface. Previous findings already pointed to a subsurface
ocean under Europa's icy crust.
The
Hubble Space Telescope is a project of international cooperation between NASA
and the European Space Agency. NASA's Goddard Space Flight Center manages the
telescope. The Space Telescope Science Institute (STScI) conducts Hubble
science operations. STScI is operated for NASA by the Association of
Universities for Research in Astronomy, Inc., in Washington, D.C.
