New study provides clearer insight into how the Moon formed and why its materials closely resemble those of Earth.

An international research collaboration has used advanced computer simulations to investigate how faint radio signals from ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its ...

The formation of the Moon billions of years ago is cloaked in mystery. Most astronomers believe the young Earth, still cooling off from its formation, was struck by a mars-sized body called Theia, ...

The Moon formed in a catastrophic impact between the proto-Earth (Gaia) and a Mars-sized object we call Theia. The collision happened around 4.5 billion years ago but its effects are still with us.

Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...

New research shows how faint radio signals from the early Universe, soon to be detected by Moon missions, could reveal dark ...
