Ganymede, larger than even Mercury and Pluto, has an icy surface speckled with bright young craters overlying a mixture of older, darker, more cratered terrain laced with grooves and ridges; the large circular feature on the upper right, called Galileo Regio, is an ancient region of unknown origin; Ganymede is thought to have an ocean layer that contains more water than Earth and might contain life; like Earth’s Moon, Ganymede keeps the same face towards its central planet, in this case Jupiter; this image was taken about 20 years ago by NASA’s Galileo probe, which ended its mission by diving into Jupiter’s atmosphere in 2003; currently, NASA’s Juno spacecraft orbits Jupiter and is studying the giant planet’s internal structure, among many other attributes.
