A stunning image of Ganymede, Jupiter's largest moon, captured by NASA's Galileo probe. The icy surface reveals a mix of young, bright craters and older, darker terrain with grooves and ridges. The prominent Galileo Regio, an ancient region of unknown origin, is visible in the upper right. Ganymede is thought to possess a subsurface ocean holding more water than Earth.
