A "gravity hole" beneath Antarctica is offering scientists a rare glimpse into Earth's deep interior, a dynamic record of slow-moving processes that have been reshaping our planet for tens of millions ...

Many people have been surprised by NASA’s latest visualization of Earth, which gives the planet a shape resembling a potato. However, the image does not show Earth’s actual physical shape. Instead, it ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...

A planet with the same mass as Earth approaches near the Moon's orbit.If such an event were to occur, what would happen to ...

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...

The Earth is a dynamic system constantly undergoing change. As the processes of change affect the Earth's topography—the heights of land, ice, and ocean surfaces—they also modify the distribution of ...

NASA is pushing back on a conspiracy about "Project Anchor" and the supposed possibility that Earth would be gravity-less for seven seconds on Wednesday, Aug. 12 "The only way for the Earth to lose ...

Testing the possibility of models of gravity different from general relativity may be closer to home than we think. In a paper published on the arXiv preprint server, a team of researchers has ...

A pair of astronomers, one with Luleå University of Technology's Asteroid Engineering Laboratory, in Finland, the other with the Southwest Research Institute, in the U.S., has found via computer ...

This article predates Brown Brothers Media’s ownership of Science Blog and has not been reviewed under our current editorial process. It is preserved as part of the publication’s archive. (A) These ...

In the chapters following this one we address specific fields of research that we believe will particularly benefit from a satellite gravity mission. In this chapter, we mention some of the ways in ...
