Should we prepare for the end of the world?
NASA's New Horizon transmits brand new, high-definition photos of Pluto's Charon.
NASA's Horizon sent back a new batch of Pluto photos -- and this time, they're in hi-res.
Pluto could possibly be host to extraterrestrial life.
Pluto might no longer be a planet, but scientists have uncovered five moons orbiting the long-distance satellite. The smallest two, previously known as P4 and P5, have finally gotten official names.
NASA researchers preparing for a spacecraft's flyby of Pluto say the distant dwarf planet at the edge of the solar system may have more moons than previously thought
One of Pluto's moons may be named Vulcan after thousands of Star Trek fans voted in a public poll to name the moon after the home planet of one of the science fiction show's iconic characters.
Pluto may not be a planet anymore, but its family keeps growing. Two new moons orbiting the dwarf planet were discovered in 2011 and 2012, and SETI is holding a contest to name them.
Scientists got a better look at one of the dwarf planets orbiting our sun, and were surprised at what they found.
NASA's New Horizons spacecraft is on a trajectory towards a potentially disastrous debris zone that could "cripple or destroy" the vehicle as it passes by Pluto, according to Johns Hopkins University scientist Hal Weaver.
