Hyperion


Despite its bathtub-ready appearance, Hyperion—Saturn's largest irregularly shaped moon—is anything but spongy.
High-resolution images taken by NASA's Cassini spacecraft—including the picture above taken in 2005—suggest the satellite's cuplike craters are reservoirs for hydrocarbons. The finding could mean that the ingredients needed for life as we know it may be more common in our solar system than previously thought, according to NASA.
Dark material spotted at the bottoms of some of the moon's craters has the same chemical signature as hydrocarbons, NASA scientists said. These organic molecules—made of hydrogen and carbon—are also found in comets, meteorites, and galactic dust.
