Beneath Antarctica's millions of square miles of ice, beneath the snow thousands of feet thick, sits dirt and rock like every other continent. In fact, scientists now say they've discovered a collection of hidden continents under Antarctica left over from millions of years ago.
The researchers from Kiel University in Germany and the British Antarctic Survey who made this surprising find were relying on data from the European Space Agency's GOCE satellite. GOCE was a simple satellite that measured the pull of Earth's gravity as it orbited the planet. By measuring exactly where Earth's gravity was strongest and weakest, scientists could paint a clear picture of the planet's structure and composition beneath the surface.
