A suspected subsurface ocean on Pluto might be old and deep. New analyses of images from NASA’s New Horizons spacecraft suggest that the dwarf planet has had an underground ocean since shortly ...

Some scientists also believe there is a liquid ocean beneath Pluto’s ice shell that is estimated to be 249 miles thick. But they thought it formed later in Pluto’s history as radioactive ...

The New Horizons spacecraft spied extensional faults on Pluto, a sign that the dwarf planet has undergone a global expansion possibly due to the slow freezing of a subsurface ocean. (Credit ...

debate. For there could be life beneath Pluto, and there could be many more ocean worlds in the Milky Way than previously thought, according to new research that theorizes that a possibly life ...

Pluto's surface, fitting for a world whose surface shivers at a cryogenic -364 F (-220 C), is frozen solid. But beneath that nitrogen ice may lie a subsurface ocean of liquid water. A recent study ...

Considering Pluto's size and composition, just 100 parts per billion of radioactive potassium would be enough to maintain an ocean 60 to 105 miles in depth 120 miles beneath the surface ...

When NASA's New Horizons spacecraft first snapped photos of an unusual heart-shaped scar on Pluto in 2015, the new view bolstered theories that the frigid world harbored an underground ocean.

And the new research may offer evidence for a subsurface ocean beneath Pluto’s icy crust. Charon and Earth’s moon are both a large fraction of the size of the main body they orbit, which is ...

Pluto's secrets are being unraveled! Astronomers have found convincing evidence of a massive ocean of liquid water hidden beneath the dwarf planet's icy surface. This exciting discovery ...

Rather than a vast ocean, Pluto’s heart might be hiding a huge, heavy treasure. Computer simulations suggest that an object about 730 kilometers wide, slightly larger than the asteroid Vesta ...
