Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...

Due to the radiative thermal conductivity of the mineral olivine, only oceanic plates over 60 million years old and subducting at more than 10 centimeters per year remain sufficiently cold to ...

Deep beneath Greenland’s vast ice sheet, scientists are uncovering a hidden source of heat that could accelerate melting and unsettle long term sea level projections. New three dimensional models of ...

Deep beneath our feet, far below the crust and mantle, Earth’s metallic heart is not as sealed off as geologists once assumed. New research indicates that gold and other precious metals are slowly ...
