A new study has reconstructed the evolution of the planet’s strongest nonhydrostatic geoid depression —the Antarctic Geoid Low (AGL)— finding that the feature has persisted for at least 70 million ...

A frozen continent at the bottom of the world sits over the deepest dip in Earth’s gravitational pull, a feature that has persisted for roughly 70 million years. Scientists have long known about this ...

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 ...

In A Nutshell Antarctica, not the Indian Ocean, hosts Earth’s strongest nonhydrostatic geoid depression when scientists measure against a reference frame that isolates internal mantle dynamics The ...

Infleqtion, a Boulder-based quantum-technology company, said this week that it “will fly the first quantum sensor capable of measuring the Earth's gravitational field and its gradients” as part of ...

“Quantum sensing opens an entirely new domain for U.S. space leadership,” said Dana Anderson, Chief Science Officer at Infleqtion. “By deploying this technology in orbit, we are demonstrating the ...

Earth gained a mini-moon this Sunday, Sept. 29 by capturing a nearby asteroid with its gravitational field. Earth pulled asteroid 2024 PT5 into its gravitational field, changing the asteroid’s orbit ...

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 ...
