Scientists have discovered what appears to be a body of liquid water as vast as the volume of the North American Great Lakes locked inside the icy shell of Jupiter's moon Europa, suggesting a potential new habitat for life and many more such lakes might exist throughout the shallow regions of Europa's shell.

Jupiter's Family Portrait - This "family portrait," a composite of the Jovian system, includes the edge of Jupiter with its Great Red Spot, and Jupiter's four largest moons, known as the Galilean satellites. From top to bottom, the moons shown are Io, Europa, Ganymede and Callisto.

Jupiter's Moons: Family Portrait - This montage shows the best views of Jupiter's four large and diverse "Galilean" satellites as seen by the Long Range Reconnaissance Imager (LORRI) on the New Horizons spacecraft during its flyby of Jupiter in late February 2007.

Ganymede Mosaic (Mar 4 1999) Credit: Galileo Project, DLR, JPL, NASA Ganymede, one of the four Galilean moons of Jupiter, is the largest moon in the Solar System. With a diameter of 5,260 kilometers it is even larger than planets Mercury and Pluto and just over three quarters the size of Mars. Ganymede is locked in synchronous rotation with Jupiter. This detailed mosaic of images from the Galileo spacecraft shows the trailing hemisphere of this planet-sized moon.
