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 ...

The curious minds at What If imagine Earth shrinking to the size of Pluto, exploring how gravity, atmosphere, and life would ...

Pluto landed its largest moon, Charon, with a 'kiss'—overturning decades of scientific assumptions about how planetary bodies form and evolve. This is the conclusion of a new study, conducted at the ...

Two space rocks are raising huge scientific questions and may pose some answers regarding the nature of our planet and of another solar system body, Pluto. Pluto has long been under siege by skeptics ...

Pluto’s frozen face looks dead at first glance, but its most famous feature hints at something far stranger than a simple ice ...

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 ...

We classified Pluto before really understanding it—just like we reduce people to job titles or put names on relationships ...

The planet Neptune wobbled in its orbit around the Sun. That could only mean one thing, astronomers said: There was a ninth planet out there, somewhere, lurking in the fringes of the solar system.

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 ...
