Earth is Actually Two Planets Fused Together

A new study conducted by UCLA researchers has uncovered an astonishing twist to the formation of Earth: it’s actually two planets fused together. Existing research had shown that a rogue planet, called Theia, had sideswiped Earth about 4.5 billion years ago, leading to the formation of the Moon. Now, scientists believe that two planets actually collided head on, leading Theia to merge with Earth to become our current home planet. Head to the Huffington Post to learn more about the discovery.
