The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...

In A Nutshell Antarctica, not the Indian Ocean, hosts Earth’s strongest nonhydrostatic geoid depression when scientists ...

A discovery about the moon made in the 1960s is helping researchers unlock secrets about Earth’s ocean today. By applying a method of calculating gravity that was first developed for the moon to data ...

Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...

A shifting of Earth’s poles, referred to as ‘True Polar Wander,” combined with the sinking of tectonic plates during the Cenozoic Era, altered the planet’s interior, with rising hot mantle material ...

After just two years in orbit, ESA’s GOCE satellite has gathered enough data to map Earth’s gravity with unrivalled precision. Scientists now have access to the most accurate model of the ‘geoid’ ever ...

The first global gravity model based on GOCE satellite data has been presented at ESA’s Living Planet Symposium. ESA launched GOCE in March 2009 to map Earth’s gravity with unprecedented accuracy and ...

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. As ...

The Earth is a dynamic system—it has a fluid, mobile atmosphere and oceans, a continually changing distribution of ice, snow, and groundwater, a fluid core undergoing hydromagnetic motion, a mantle ...

While a "gravity hole" in Antarctica has been on scientists’ radar for some time, its history has never been fully understood. New research is beginning to change that, and in doing so, suggest ...
