According to a recent YouGov poll, 35% of Americans think Pluto is not a planet. But they are all wrong—kind of. To get to ...

Pluto likely acquired large moon Charon in a “kiss and capture” collision billions of years ago. It may have created a subsurface ocean on the icy dwarf planet.

The incident could have created enough heat for Pluto to form an underground ocean, Adeene Denton, the lead researcher, told Mashable. It's an intriguing implication, supporting existing ...

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

However, this new research—published this week in Nature Astronomy—also suggests that Pluto has no subsurface ocean. While the vast majority of Pluto's surface consists of methane ice and its ...

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 ...

And the new research may offer evidence for a subsurface ocean beneath Pluto’s icy crust. Charon and Earth’s moon are both a large fraction of the size of the main body they orbit, which is ...

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 ...
