Imagine a hidden planet within Earth, buried hundreds of kilometers beneath our feet. This discovery is not science fiction, ...

Soon after the Earth coalesced in the early solar system, it was hit by another planet, Theia. The collision formed the moon, but researchers are still trying to piece together exactly what ...

Molten slabs of Theia could have embedded themselves within Earth's mantle after impact before solidifying, leaving portions of the ancient planet's material resting above Earth's core some 1,800 ...

It’s generally thought that Earth did live through an apocalypse of planetary proportions about 4.5 billion years ago, when a Mars-sized planet named Theia slammed into it.

Theia, an ancient planet, collided with Earth to form the moon, scientists believe. A new study suggests Theia could have also formed mysterious blobs called large low-velocity provinces, or LLVPs.

Astronomers have long suspected that the Moon formed roughly 4.5 billion years ago when a hefty planet-in-the-making called Theia collided with a young Earth.

Researchers have long suspected that the Moon was formed after a Mars-sized protoplanet, dubbed Theia, smashed into the primordial Earth some 4.5 billion years ago. The literally Earth-shattering ...

According to Yuan, these blobs are between 1.5 and 3.5% more dense than the rest of Earth's mantle, and hotter. If the planet Theia was rich in iron and highly dense, Yuan's models showed, any ...

But recent analysis of material taken from the Apollo 12, 15, and 17 missions tells a different tale: that of a violent head-on collision, one that left the Earth forever scarred with the ...

Molten slabs of Theia could have embedded themselves within Earth’s mantle after impact before solidifying, leaving portions of the ancient planet’s material resting above Earth’s core some ...
