A map of the Gulf of Mexico region colored to show minute changes in gravity caused by different rock types -- areas of strongest gravity are in purple, and weakest in blue. Knowing where rock ...

The moon has a surface gravity of around 1.62 meters per second squared, according to NASA. In comparison, the Earth has a surface gravity of approximately 9.8 meters per second squared.

Launched in 2002, the twin Grace satellites map Earth’s gravity field from orbit 500 kilometers (310 miles) above the surface. They respond to how mass is distributed in the Earth and on Earth ...

The new map homes in on a lingering concern of Einstein’s general relativity: how the most massive objects in the universe, like supermassive black holes, bend light from more distant sources.

A ‘gravity hole’ on Earth? Earlier this summer, researchers with the Indian Institute of Science published a paper exploring one of these ‘gravity holes’. Found all over the… ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets. A ...

There is no true "up" or "down" in space. Gravity pulls objects toward the core of the Earth, creating the sensation of being upright, physicists say. The photo in the post has been distorted.

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as "fundamental" as gravity -- and could even give clues about possible life on other planets.
