The Earth’s inner core is 3,000 miles below the surface and was thought to be a solid sphere held by gravity in the molten ...

Using tiny deviations in satellite orbits to map Mars' gravity field, the researchers were able to detect anomalies below the ...

A new study has revealed that gravity’s effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field.

With a radius of 2,106 miles, Mars is the seventh largest planet in our solar system and about half the diameter of Earth. Its surface gravity is 37.5 percent of Earth’s. Mars rotates on its ...

Bouncing back from under the weight of Ice Age glaciers which have long since vanished, the Nordic region land mass is slowly ...
