If you lived on one of Pluto’s moons Nix or Hydra, you’d have a hard time setting your alarm clock. That’s because you could not know for sure when, or even in which direction, the sun would rise. A ...

Back in the 1980’s, a now-defunct magazine called Science Digest held a contest to name Planet X — the still-undiscovered world that astronomers believed might lie out beyond Pluto. One of the best ...

Some 4.5 billion years ago, the dwarf planet Pluto was suddenly joined by a companion. For a brief period – perhaps only hours – they danced as if arm in arm before gently separating, a grand do-si-do ...

In the Feb. 23 issue of the journal Nature, a team led by Dr. Hal Weaver of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., describes its discovery of two new moons ...

Finally, a family portrait of Pluto is beginning to emerge! For the first time ever, astronomers have captured two never-before-photographed moons orbiting Pluto. NASA's New Horizons spacecraft ...

Simulation of the moon Nix which orbits Pluto every 25 days. Here that's sped up to one orbit every two seconds, so we can see its chaotic spin more clearly. Little moons in the solar system have it ...

Scientists using the Hubble Space Telescope have discovered what they say are two more tiny moons orbiting the planet Pluto, the first evidence yet that any object in the solar system beyond Neptune ...

People might disagree on whether Pluto should be considered a planet or a dwarf planet but no one disagrees this world is peculiar. Everything about it is so weird, from its heart to the fact that ...

New research suggests that billions of years ago, Pluto may have captured its largest moon, Charon, with a very brief icy ...

Charon is large in size relative to Pluto, and is locked in a tight orbit with the dwarf planet. A new simulation suggests how it ended up there. By Jonathan O’Callaghan Some 4.5 billion years ago, ...
