A new study shows that slow, deep rock currents inside the Earth have helped shape the planet's strongest large-scale gravitational anomaly under the Antarctic continent. Why is gravity weaker over ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

Gravity feels steady. You drop a set of keys, and they fall the same way every time. That reliability makes it tempting to picture Earth’s pull as uniform. It is not. After accounting for Earth’s ...

A balloon-borne experiment over Antarctica, designed to detect cosmic radio waves, has instead picked up bizarre signals that appear to be coming from deep within the ice. These signals challenge our ...
