New images of Pluto’s largest moon, Charon, reveal details of markedly violent past.

NASA published striking photos taken by the New Horizons spacecraft at the culmination of its 9-year mission to Pluto, which show an array of mountains, valleys, and canyons on the dwarf planet’s moon.

According to NASA, a system of canyons located just north of the moon’s equator is quadruple the length of the the Grand Canyon, and twice as deep in some areas indicating a “titanic geological upheaval in Charon’s past.”

The images were captured by New Horizons when the spacecraft traveled past the dwarf planet and its moon on July 14 and they were transmitted to Earth on Sept. 21.
