Pluto—Did it Have an Ocean?

Five years ago, New Horizons spacecraft flew past Pluto and took detailed photographs. Since then, scientists have been studying Pluto’s surface for clues about how it formed. And the results are surprising! Well, for them anyway!

Secular astronomers expected Pluto to be heavily cratered, but it’s not. Instead it has a “young” surface. It’s believed this means there’s been geological activity.

Now, that requires heat. But Pluto’s far from the sun. So this heat must’ve come from when Pluto was formed, which couldn’t’ve been millions of years ago.

The more we study the heavens, we see they declare a young universe.
