European scientists just unearthed a major piece of geologic history — data from a long-retired satellite revealed ancient landmasses hidden beneath Antarctica.
The European Space Agency’s Gravity field and Ocean Circulation Explorer satellite was retired five years ago, but while it was running it produced maps of the how the Earth’s gravitational field varies around the globe.
By combining that data with seismological reports, geologists at Germany’s Kiel University were able to create 3D maps of the previously-unexamined crust beneath Antarctica’s ice.
