Some 4.5 billion years ago, a Mars-sized rock is theorized to have collided with the proto-Earth. The collision is one of the only ways to create an Earth-Moon system with the properties we observe ...

The big picture: Theia is a hypothetical ancient planet that orbited the Sun during the formation of the solar system. According to the giant-impact hypothesis, this protoplanet collided with Earth ...

Scientists from the Durham University and University of Glasgow worked together in developing simulations using supercomputers that may explain how the Moon may have formed after a collision between ...
