Twin NASA probes orbiting the moon have generated the highest resolution gravity field map of any celestial body. The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, ...

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 ...

A new map of Mars’ gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. “Gravity maps allow us to see inside ...

A discovery about the moon made in the 1960s is helping researchers unlock secrets about Earth’s ocean today. By applying a method of calculating gravity that was first developed for the moon to data ...

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. "Gravity maps allow us to see inside ...

Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...

AMAZING GRACE Data collected by the twin Gravity Recovery and Climate Experiment (Grace) satellites have produced the most accurate map yet of Earth's geoid, or gravity field, even before the ...

On March 17, 2002, the satellite duo GRACE was launched to map the Earth's gravity field more precisely than ever before. The measurements make it possible to monitor the terrestrial water cycle, the ...

Gravity map of Mars. The red circles show prominent volcanoes on Mars and the black circles show impact crates with a diameter larger than a few 100 km. A gravity high signal is located in the ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

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 ...
