Data from NASA’s New Horizons spacecraft point to more prevalent water ice on Pluto’s surface than previously thought. A new false-color image, derived from observations in infrared light by the Ralph ...

Pluto's heart of ice is even colder than we originally thought. NASA recently revealed that the lonely planet, which we so cruelly voted out of our solar system in 2006, contains far more water ice ...

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 ...

In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it ...

New maps released by NASA show that the dwarf planet has more water ice than previously thought. The data taken by the New Horizons spacecraft captures more prevalent frozen water on Pluto's surface, ...

This false-color infrared image from NASA’s New Horizons spacecraft shows water ice concentrations on Pluto. The left image is the result of an initial analysis, and the right image has been ...

Planetary scientists have suspected for months the presence of water on Pluto in the form of towering ice mountains (shown below) — some of which rival Earth's Rocky Mountains in height. But it wasn't ...

Irving Berlin surely didn't have Pluto in mind when he wrote "Blue Skies" in 1926—four years before the dwarf planet was discovered by astronomer Clyde Tombaugh—and it's unlikely that Ella Fitzgerald, ...

This week's discovery of 11,000-foot-high mountains on Pluto — and the implication that they're made of water ice — is stimulating all sorts of wonderings about what may be going on beneath the ...

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 ...
