Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ago. Scientists led by ...

Imagine Earth containing the remnants of an ancient planet locked within its mantle. This intriguing concept has gained momentum with recently emerging seismic research showing two gigantic structures ...

About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...

A new study has determined with 99.9% accuracy that the Moon was formed 95 million years after the birth of the Solar System. This pegs the Moon as being a lot younger than we previously thought -- ...

A research team has discovered another piece in the puzzle of the formation of the Moon and water on Earth. The prevailing theory was that the Moon was the result of a collision between the early ...

Most scientists agree that a major collision 4.5 billion years ago with a protoplanet named Theia formed the Earth-Moon system. Now, a new study from the University of Nevada argues that, out of the ...

About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly ...

About 4.5 billion years ago, the most momentous event in the history of our planet occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what ...

The Moon was formed by a violent, head-on collision between the early Earth and a “planetary embryo” called Theia approximately 100 million years after the Earth formed, UCLA geochemists and ...
