Pluto's snow-capped mountains look like they belong on Earth, but researchers have discovered that the snowy tops of these features are actually made of methane frost. Pluto's snow-capped mountains ...

Unlike how scientists believe Earth's moon formed billions of years ago, Pluto and its biggest moon, Charon, didn't have a messy breakup. New computer simulations show the primitive dwarf planet and ...

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

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 ...

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 ...

Using advanced models, SwRI led new research that indicates that the formation of Pluto and Charon may parallel that of the Earth-Moon system. In the resulting “kiss-and-capture” regime, Pluto and ...
