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

To understand the "blood moon", we must first discuss the total lunar eclipse.

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

The moon's orbit isn't a perfect circle. Instead, it's more stretched out, kind of like an oval, which means its distance from Earth varies by about 30,000 miles (48,000 km). The surface of the moon ...

An international research collaboration has used advanced computer simulations to investigate how faint radio signals from ...

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 ...

September’s full moon will be accompanied by a total lunar eclipse that will be visible to much of the world. Here’s how to ...

A physicist, a chemist, and a mathematician walk into a bar. It sounds like the start of a bad joke, but in my case, it was the start of an idea that could reshape how scientists think about the ...

Lunar dust collected by Apollo 17 astronauts in the 1970s has revealed that the moon is 40 million years older than previously believed. After landing on the moon on December 11, 1972, NASA astronauts ...
