The moon's near and far sides exhibit striking asymmetry—from topography and crustal thickness to volcanic activity—yet the ...

Understanding the Moon’s history requires examining its formation and the events that shaped its surface. For years, scientists have debated its age, with estimates ranging from approximately 4. ...

New simulations show the Moon may have coalesced within hours of the catastrophic Theia-Earth collision that took place billions of years ago.

There are several theories about how the Earth and the Moon were formed, most involving a giant impact.

In a recent study published in The Astrophysical Journal Letters, an international team of researchers led by Durham University use supercomputer simulations to theorize that the Earth’s Moon formed ...

New research challenges ancient estimates, revealing the moon's true age and reshaping our understanding of its formation ...

The history of the moon and Earth Pinpointing when the moon solidified gives future researchers a reference point for modeling the moon’s evolution.

The moon formed after a collision 4.5 billion years ago between the young Earth and a Mars-sized object, called Theia – but what happened next? Scientists have theorised that a disc of debris slowly ...

A detailed supercomputer simulation of a titanic impact on early Earth shows the moon may have formed much faster than scientists imagined.

Scientists have used the most detailed supercomputer simulations yet to reveal an alternative explanation for the moon's origin.
