Astronomers say they are one step closer to 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 ...

Recent studies, detailed in publications 'Nature', have identified intriguing anomalies known as large low-velocity provinces within Earth's lower mantle. These structures are theorized to contain ...

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 preserved, ...

The Moon may have formed almost immediately following a devastating impact between Earth and a Mars-sized world in the ancient past, according to the results of a new supercomputer study. Earth’s moon ...

New research may solve a persistent mystery about how Earth's Moon formed. New clues to the origin of the Moon surfaced this week, which reveal that the Earth and Moon are not as similar as previously ...

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. Now, researchers have found evidence that ...

Scientists think a planet may have crashed into Earth 4.5 billion years ago, creating the moon. This alien planet, Theia, was thought to have completely disappeared in the collision. A new study ...

The mystery of the Earth and Moon’s similarity Early models of the Moon’s formation predicted that the Moon should mostly consist of Theia’s material. But scientists noticed a puzzle: Earth and the ...
