The researchers postulate that the massive collision of Theia and Earth could explain the existence of enormous 'Low Velocity ...

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 ...

About 4.45 billion years ago, 150 million years after the solar system formed, Earth was hit by a Mars-size object called Theia. The collision created the moon, but debate has raged exactly what ...

Possibly, gravitational pushes and pulls from other planets nearby put Theia on a collision course with Earth. Initially, astronomers believed the Moon had formed by some other means. Some thought ...

involving a Mars-sized 'Theia' and proto-Earth. In this image, the proposed hit-and-run collision is simulated in 3D, shown about an hour after impact. A cut-away view shows the iron cores.

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 ...

This last collision, also known as the “moon-forming impact ... mixing up all the different oxygen isotopes and erasing any original differences between the Earth and Theia. However, there are many ...

New research explores if the moon was captured by Earth or formed by a collision. Scientists weigh theories, analyzing lunar ...

a colossal collision, termed the "giant impact," unfolded between the fledgling Earth, known as Gaia, and a proto-planet the size of Mars named Theia. This catastrophic encounter between Gaia and ...

A new study suggests Earth’s Moon may have been “captured” from a binary system, challenging the long-held impact theory and ...
