As they whirl around in low-Earth orbit, satellite configurations are far more sensitive to changes in Earth's gravity field ...

Most of us take gravity for granted. You jump, you fall down to earth. It’s pretty simple, right? Well, in some places on ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

As the story goes, mathematician Sir Isaac Newton was sitting in an orchard after supper when he saw an apple fall from a tree. He wondered why apples always fall straight to the ground, instead of ...

Gravity is what holds Earth in orbit around the sun and keeps us from floating off into space. Unfortunately, it can — quite ...

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve. When ...

These gravity-defying spots remind us how much wonder the world holds. Mysterious places where gravity seems to work in reverse [YouTube] Gravity, the force that keeps everything anchored to Earth, is ...

Bottom line: There's a well-known "hole" in Earth's gravity field just off India's coastline, known as the Indian Ocean Geoid Low (IOGL). A new study is providing a potential explanation for this ...

Though Mercury is the closest planet to Earth, it’s one of the hardest to reach. Any spacecraft heading inward must fight the ...

In 2007, something strange happened over the eastern Atlantic Ocean. According to satellites orbiting Earth, our planet's gravity field developed a continent-scale anomaly before subsiding to its ...
