Astronomers have taken a step towards 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 led by ...

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

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

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, ...

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

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 ...

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.

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...

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