which we can then tie to Pluto's contemporary geology to test. "I'd really like to determine how the initial Pluto-Charon impact can influence whether and how Pluto and Charon develop oceans." ...

The scenario also could support Pluto's active geology and possible subsurface ocean, despite its location at the frozen edge of the solar system. A NASA postdoctoral researcher at Southwest ...

Scientists have discovered a new type of planetary collision called “kiss-and-capture,” where Pluto and proto-Charon briefly ...

When manipulated, they reveal a wealth of scientific information. This image uses 'false-colour' to show how the geology of Pluto's surface varies. It reveals how much light is reflected by ...

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 ...
