Researchers have proposed many origins for a gravity anomaly in Wilkes Land, East Antarctica, but the latest evidence suggests the subglacial hole is an impact crater measuring 315 miles across.

Deep beneath the ice of East Antarctica’s Wilkes Land, scientists have identified a vast gravitational anomaly that could ...

The crater was first noticed because of a strange dip in Earth’s gravitational field. Back then, ground-based surveys using ...

A giant gravity dip beneath Antarctica may mark a planet-shifting impact. The Wilkes Land anomaly hints at an ancient cosmic ...
