For decades, astronomers have tried to determine how Pluto acquired its unusually large moon Charon, which is about half the size of the dwarf planet. Now, new research suggests that Pluto and Charon ...

This close up look at Pluto and Charon, taken as part of the mission's latest optical navigation ("OpNav") campaign from Jan. 25-31, 2015, comes from the Long Range Reconnaissance Imager (LORRI) on ...

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, ...

The icy volcanism of Charon may be caused by its internal ocean freezing, expanding, and cracking the outer shell of the moon if it was thinner than expected. When you purchase through links on our ...

Labroots recently explored Saturn’s sponge-like moon, Hyperion, with its deep craters and non-spherical shape. This moon is an example of how the Universe and the laws of astrophysics work in both ...

New research suggests that billions of years ago, Pluto may have captured its largest moon, Charon, with a very brief icy "kiss." The theory could explain how the dwarf planet (yeah, we wish Pluto was ...

How did Pluto and its largest moon, Charon, form? This is what a recent study published in Nature Geoscience hopes to address as an international team of researchers led by the University of Arizona ...

The first color movies from NASA’s New Horizons mission show Pluto and its largest moon, Charon, and the complex orbital dance of the two bodies, known as a double planet. “It’s exciting to see Pluto ...

In a paper published today in Nature, a team of U.S. scientists led by Dr. S. Alan Stern of Southwest Research Institute (SwRI), concludes that two newly discovered small moons of Pluto were very ...

In the vastness of outer space, meetups between celestial bodies can be few and far between. But when they do happen, even the briefest affairs can leave behind permanent scars. For scientists probing ...
