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

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 ...

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 ...

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 ...

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 ...

Everything we thought we knew about the moon's origins may be wrong, new research suggests. Ever since we landed the first humans on the moon, scientists have thought that our lone lunar companion ...

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 is getting 1½ inches (3.8 centimeters) farther away from the Earth every year. Scientists measure the distance to ...
