Ten years ago today—on July 14, 2015—our New Horizons spacecraft made history, flying less than XXXXX miles (13,000 km) over the surface of Pluto. In addition to taking our closest look ever at the distant, icy world, New Horizons also observed Charon, the largest of Pluto's five moons.

New Horizons studied the famous "heart" on Pluto's surface: its left half, a sheet of nitrogen ice known as Sputnik Planitia, is so big that it literally changed how Pluto rotates. Thanks to New Horizons' photos and data, astronomers now think that Pluto could still have active cryovolcanoes, and may even hold a vast, liquid ocean sloshing beneath its surface.
