Pluto’s largest moon is cracked

Charon, Pluto’s largest moon, is cracked! Photos taken by NASA’s New Horizons space probe, revealed a 1,600 km long chasm stretching across the face of Charon. That’s over four times longer than the Grand Canyon and almost twice as deep in places. Researchers opine that an internal water ocean could have frozen long ago, and the resulting volume change could have led to Charon cracking open, allowing water-based lavas to reach the surface.
