Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same. A ...

Geoscientists say Earth will be home to one massive supercontinent about 200 million years from now; there are four prominent versions of this mega-continent. The climate might be surprisingly balmy ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

First global map of mantle earthquakes reveals seismic activity far beneath continents, challenging old ideas about Earth’s ...
