When we’re told about newly released satellite images of our Earth, we imagine beautiful swathes of green and blue with the occasional white of swirling storm clouds or snow-topped mountain ranges.

Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

Learn how we know the Earth is round, and the science behind the shape of our gravitational field.

The region of lower gravity, discovered in 1948, manifests as a vast depression in the ocean's surface that reaches some 348 feet deep at its greatest extent. A mysterious “gravity hole” in the Indian ...

[UPDATE (April 5, 2011): It turns out some of the descriptions I used below to describe a geoid were not accurate. I refer you to this page at the University of Oklahoma for a good description. I've ...

Scientists have known about the existence of a 'gravity hole' in Indian Ocean for decades but have long been left puzzled as to why it exists. Known officially as the 'Indian Ocean Geoid Low', it ...

A huge, mysterious so-called “gravity hole” under the Indian Ocean might have been formed from the remnants of an ancient sea, according to a new study. Researchers recently offered the possible ...
