The moon came to be when the Earth collided with a smaller planet named Theia. However, no remains of this smaller planet have ever been found, which has puzzled scientists for years. These new ...

A new paper disputes the widely accepted hypothesis that the Moon is the product of material thrown up when an object known ...

There's been some new research about an ancient planet - called Theia - that experts think helped form the Earth we know today. Scientists think that Theia crashed into Earth billions of years ago ...

These structures are theorized to contain remnants of Theia's materials, offering valuable insights into the ancient collision. The presence of large low-velocity provinces in Earth's mantle ...

mixing up all the different oxygen isotopes and erasing any original differences between the Earth and Theia. However, there are many differences between the chemistry of the Earth and the moon, too.

A detailed simulation of Theia crashing into Earth. While the collision was violent, it was not energetic enough to melt the Earth's lower mantle -- meaning that remnants of Theia could be ...

Before Earth and the Moon, there were proto-Earth and Theia (a roughly Mars-sized planet). The giant-impact model suggests that at some point in Earth's very early history, these two bodies collided.

Oct. 4, 2022 — Most theories claim the Moon formed out of the debris of a collision between the Earth and an object about the size of Mars, called Theia, coalescing in orbit over months or years.

A group of scientists from Arizona State University suggested the blobs are remnants of a "Mars-sized planetary embryo" named Theia, which struck Earth in its infancy 4.5 billion years ago.

However, how the moon formed is generally accepted to be after a “great impact” between Earth and a protoplanet. The giant-impact theory proposes that a Mars-sized planet, now called Theia ...

The moon is thought to have formed following a collision between Earth and a Mars-sized object, called Theia. But now Jacob Kegerreis at Durham University’s Institute for Computational Cosmology ...

Scientists suggest that Jupiter played a significant role in the chaotic early years of the solar system, potentially contributing to the formation of Earth's moon. The so-called "great ...
