The "Potsdam Gravity potato", as this representation of terrestrial gravity has become known, can for the first time display gravity variations that change with time. The seasonal fluctuations of the ...

We don’t often think about gravity, the invisible force that anchors us to Earth, as it always seems constant and dependable. However, it will slightly vary, sometimes by enough to make you weigh ...

A joint Australian-German research team led by Curtin University's Dr Christian Hirt has created the highest-resolution maps of Earth's gravity field to date -- showing gravitational variations up to ...

Small gravitational tugs from waterlogged river basins could give scientists a big advantage in predicting devastating floods, researchers report July 6 in Nature Geoscience. Hydrologist J.T. Reager ...

Six months into its mission to precisely measure Earth's shifting water masses and map their effects on Earth's gravity field, the joint NASA-German Aerospace Center Gravity Recovery and Climate ...

We are fascinated by the gravitational differences between other planets, but rarely do we recognize the gravitational variations upon our own. If Earth was a perfectly smooth sphere of equal density ...

There's going to be a changing of the guard in space. On Tuesday, NASA is launching two new satellites, collectively called GRACE, to replace two that have been retired after 16 years in orbit. GRACE ...

Scientists using NASA satellite data found the shape of the Earth appears to be influenced by big climate events that cause changes in the mass of water stored in oceans, continents and atmosphere.

Astronomers have identified a tightly bound pair of stars that are spiraling toward a catastrophic merger, turning a distant stellar system into a natural laboratory for testing gravity at its most ...

Scientists have used gravitational measurements from the low-flying Goce satellite to map the boundary between the earth’s crust and its mantle in unprecedented detail. The Mohorovicic or “Moho” ...
