"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 ...

An artistic rendering of a dust and gas disk encircling the young exoplanet, CT Cha b, 625 light-years from Earth. Spectroscopic data from NASA’s JWST suggest the disk contains the raw materials for ...

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 ...

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

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 ...

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 ...

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 ...
