Scientists have long believed that the Moon was formed by a massive object crashing into the Earth. But what was that thing ...

"During the early solar system's game of cosmic billiards, Earth was struck by a neighbor,” said Dauphas. “It was a lucky shot. Without the moon's steadying influence on our planet's tilt, the climate ...

The formation of the Moon may have come harder on the heels of Earth's birth than we thought. According to a new analysis by researchers from the US, France, and Germany, Earth's constant companion ...

Billions of years ago, so the theory goes, something around the size of Mars smacked into Earth, spewing a whole bunch of dirt into space that eventually coalesced to form the Moon. This is called the ...

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across ...

A groundbreaking study in Nature has shaken up our understanding of the moon’s formation. This research suggests that the moon was born during Earth’s earliest days, revolutionizing the timeline of ...

The moon is much older than we thought, according to a new analysis conducted by researchers from the United States, France, and Germany. It is possible that Earth's companion formed as early as 4.53 ...

Scientists have gone back and forth about explanations for the moon's formation for decades, with the general consensus being that it formed during some type of cosmic collision between Earth and a ...

That timeline is based on analyses of lunar rock samples from NASA’s Apollo missions. But the new study suggests that the moon formed earlier — around 4.51 billion years ago — and then experienced a ...

How did the Moon form? Was it from a collision, as has been the longstanding theory, or could it have been captured by the Earth early in our planet’s formation? This is what a recent study published ...

Apollo samples provide evidence: Researchers analyzed Moon rocks brought back by the Apollo missions and, for the first time, ...

Two primary theories explain planetary moon formation: gravitational capture within a planet's Hill sphere radius and simultaneous formation with the solar system during its accretion disk phase. A ...
