This is where it leaves a tangible imprint, evidence that there exists a force more powerful than gravity at work within the Earth whose influence extends very far. Way back in the earliest ...

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's ...

Instead, this force can vary depending on where you are. For example, gravity’s effects on Earth at the equator are different, as the pull is weaker there. Gravity is changing parts of our ...

Jeff Bezos’ rocket company has given NASA a brief taste of the moon’s gravity without straying too far from home.

For example, Jupiter is the most massive planet in our solar system. It’s so big, it could swallow 1,000 Earths. So it requires a very high escape speed: 133,100 mph (about 214,000 kilometers per hour ...

For a brief, but exciting, time last year, Earth had two moons. A small asteroid lingered close to our planet in its orbit ...
