-- Check out this space canyon!
The canyon, which is informally named Argo Chasma, is estimated to be 430 miles long and as deep as 5.5 miles, according to NASA. By comparison, the Grand Canyon in Arizona is 280 miles long and is a little more than a mile deep.
The image was taken when New Horizons was 289,000 miles away from Charon. The space probe made a historic flyby of Pluto and its moons last July, and has since been sending photos and data back to Earth.
The spacecraft, equipped with a power system that converts radiation from decaying plutonium into electricity, loses about a few watts each year but may have enough power for two more decades of exploration, according to NASA. It's currently moving through the Kuiper Belt, an area full of tiny, icy worlds at the edge of the solar system.
