Astronomers have just found the best evidence yet of an entire ocean in an exceedingly unlikely place—the dwarf planet Pluto, in the dark hinterlands of the solar system. There, nitrogen and other ...

A new study proposes that Pluto formed rapidly with a hot interior, subsequently sustaining a subsurface liquid ocean for billions of years, contrary to prior cold-start formation theories. Geological ...

Michelle Starr is CNET's science editor, and she hopes to get you as enthralled with the wonders of the universe as she is. When she's not daydreaming about flying through space, she's daydreaming ...

If you’re planning on visiting Pluto anytime soon, best to bring some warm boots. A frigid, possibly “slushy” subsurface ocean could be lurking under the crust of the dwarf planet, according to a new ...

When NASA’s New Horizons spacecraft flew past Pluto in 2015, researchers hoped that its data would help them unravel some of the dwarf planet’s mysteries. Instead, the discoveries made during the ...

(CNN) --Today, the dwarf planet Pluto orbits the sun from the edge of our solar system and its surface temperature is an inhospitable negative 378 to negative 396 degrees Fahrenheit. But a new study ...

Sputnik Planitia, the left lobe of Pluto’s “heart,” is thought to have formed as the result of a giant impact early in the dwarf planet’s history. This graphic shows how the icy world reoriented ...

Pluto is hiding a very big secret some 3 billion miles away from Earth: a vast ocean of liquid water. If you could suck all of the liquid from below the dwarf planet's icy shell, it might amount to a ...

It seems Pluto is incapable of running out of surprises. The latest research suggests the tiny dwarf planet may hold a vast subsurface ocean under its icy crust. When NASA's New Horizons spacecraft ...

The left side of Pluto’s bright “heart” is known informally as Sputnik Planum. (Credit: NASA / JHUAPL / SwRI) Scientists have been saying for months that Pluto could have a salty, sloshing ocean ...

Pluto's iconic icy heart is likely harboring a slushy ocean with layers of frozen nitrogen and water ice, which best explains the features revealed after the New Horizons spacecraft flyby, a new study ...
