This composite image of Pluto, right, and Charon, its largest moon, showcases photos captured by NASA’s New Horizons spacecraft in July 2015. Unlike how scientists believe Earth's moon formed billions ...

The love story between Pluto and Charon may have started with a kiss. A new study suggests the dwarf planet and its scarcely smaller moon likely came together in a collision that saw them conjoined ...

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

Pluto's largest moon, Charon, likely formed through a capture event in the early, crowded Kuiper Belt. Three-body encounters and tidal forces allowed Charon to lose energy and become permanently bound ...

Scientists have been blown away by Pluto’s complex geology in the months following NASA’s historic flyby of the dwarf planet. But it’s not the only interesting world in its system: Charon, Pluto’s ...

JWST detected carbon dioxide and hydrogen peroxide on Charon's surface. Hydrogen peroxide suggests ongoing chemical reactions on Charon. Charon's carbon dioxide likely came from below its surface.

It took NASA's New Horizons spacecraft almost a decade to reach Pluto and its moon, Charon, and it didn't get to hang around long before zooming off into the outer solar system. Scientists from the ...

For billions of years, Pluto and its largest moon Charon have been facing each other in a mutual tidal lock. Since it’s about half the size of Pluto, the moon and its planet are sometimes referred to ...

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 ...

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 ...
