Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a major storage place for hydrogen, possibly equivalent to dozens of oceans’ ...

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has ...

Researchers from the Australian National University (ANU) have discovered evidence suggesting that the Earth’s inner core is solid, according to a study published in the ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...

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 ...
