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.

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 ...

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 ...

Pluto landed its largest moon, Charon, with a 'kiss'—overturning decades of scientific assumptions about how planetary bodies form and evolve. This is the conclusion of a new study, conducted at the ...

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 ...

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 ...

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 ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...
