New images from the New Horizons probe suggest that Charon once had a sub-surface ocean of liquid water.
Situated 3.6 billion miles away in the cold, distant reaches of the solar system, the small world of Pluto had always seemed like an unlikely place to find signs of liquid water.
Now though scientists have revealed that not only is there evidence of water on Pluto, its moon Charon may have also been home to a sub-surface ocean of liquid water in the distant past.
The discovery was made thanks to images returned by NASA’s New Horizons probe which show huge faults and chasms on Charon’s surface – some four times deeper than the Grand Canyon.
