Learn how we know the Earth is round, and the science behind the shape of our gravitational field.

We are fascinated by the gravitational differences between other planets, but rarely do we recognize the gravitational variations upon our own. If Earth was a perfectly smooth sphere of equal density ...

Buckle up, nerds: NASA is building the first quantum gravity sensor for space—a suitcase-sized instrument that could soon be measuring everything from subterranean water to hidden reserves of ...

The first image released from the Gravity Recovery and Climate Experiment (Grace), a joint NASA-German Aerospace Center mission, graphically illustrates the sensitivity of the mission’s twin ...

Khosro Ghobadi-Far is advancing the science of climate change with orbiting satellites. Ghobadi-Far has earned an $800,000 grant from NASA to analyze data from the GRACE-FO satellites, which measure ...
