Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes ...

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 ...

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 ...

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

Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. Here’s what happened.

started rising. As the ground rebounded in this fashion, the gravity field changed. “The Earth behaved much like putting your finger into a sponge ball and watching it slowly bounce back,” said ...

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 ...

Thanks to Newton, we all know that what comes up must come down. But did you know that what comes down comes down with just slightly less pressure if you're standing in Europe or the South Pacific? We ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

A new ESA study predicts that the devastating Sumatran earthquake, which resulted in the tragic tsunami of 26 December 2004, will have left a ‘scar’ on Earth’s gravity that could be detected by a ...

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 ...
