Missing link of planetary formation discovered

Ultima-Thule

What has New Horizons found at Ultima Thule?

Remote observations have suggested that Ultima Thule has a lumpy shape, or could even be two bodies in orbit around each other. Image Credits: NASA/JHUAPL/SwRI/Steve Gribben

Interview: Ramy El-Maarry, New Horizons scientist

An eye-shaped nebula, the remains of a star forming molecular cloud that is being torn apart by the supergiant at it's center. The glowing parts of the planet's atmosphere in the lower left are portions of atmosphere that were ionized either because of meteorite impacts or massive volcanic eruptions. This is a young planetary system, still in the heavy bombardment stage of its formation, so impacts are still very common. The ring of glowing debris around the planet are the remains of it's other moons, which were obliterated in a series of collisions.

How did the Solar System form?
