Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by ...

The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve. When ...

Earth, in most renderings, is a smooth sphere with a glossy complexion—a blue marble, as pictures snapped from space have shown us. Earth scientists know that’s not exactly true. Earth, in fact, is an ...

satellite configurations are far more sensitive to changes in Earth's gravity field than sensors on the surface. They stay ...

In the pursuit of finding anomalies that did not have connection to surface changes, researchers detected one that happened in 2006 and ended in 2008.

You may have seen videos of astronauts jumping on the moon. Their movements appear bouncier and lighter than how we move on Earth, and this is thanks to gravity. Gravity is "the force by which a ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...
