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 ...

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 ...

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

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 may be more than 100 million years older than some scientists previously thought, according to a new study. The research, published Wednesday in the journal Nature, challenges the ...
