Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by a mineral shift deep within Earth's mantle. GRACE satellites detected a ...

There’s a new entrant in the competition to develop ever-tinier instruments that can detect changes in our planet’s gravitational field — a tabletop device roughly the size of two smartphone stacked ...

On March 17, 2002, the German-US satellite duo GRACE (Gravity Recovery and Climate Experiment) were launched to map the global gravitational field with unprecedented precision. After all, the mission ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

Researchers think they’ve found the reason for the most significant drop in Earth’s gravity, known as the Indian Ocean geoid low. In this location in the Indian Ocean south of Sri Lanka, our planet’s ...

Here’s what you will learn when you read this story: Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. These anomalies are ...
