Scientists have discovered that the Moon-forming collision may have depended heavily on how hot and physically strong early ...

The findings, published in The Astrophysical Journal Letters, account for the material strength of the two colliding worlds ...

New simulations suggest the moon may have formed almost instantly after a giant impact, not slowly from a debris disk.

The research could also influence the hunt for exomoons, which orbit planets outside our solar system.

How did Earth get its Moon? New simulations suggest a Mars-sized body called Theia collided with Earth 4.5 billion years ago, and the Moon could have formed within hours.

Treating ancient Earth and Theia as solid geological bodies transforms simulations of the collision that may have created the ...

Scientists have found that the Moon may have formed within hours after the giant impact that shaped Earth's early history.

Imagine looking up at the night sky and seeing something impossible. The Moon is no longer alone. A tiny new object has ...

The Moon's permanently shadowed craters contain water ice, but estimates of the available supply raise a major question about the future of lunar settlements.

Scientists have long speculated why Venus, with a similar size, mass, and structure to Earth, doesn’t have a moon. New UC Riverside research shows it’s because our hungry twin likely swall ...

Planets without stars to orbit raise important questions about how planets evolve and what habitability might look like ...

Turkey is moving closer to the Moon. TAI’s first homegrown lunar spacecraft has completed production and entered environmental testing ahead of a planned 2027 mission.
