Geochemical studies of volcanic rocks from Baffin Island, Canada, and Iceland suggest that some of the water dating back to ...

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’ ...

Researchers at Göttingen University have uncovered new evidence that some of Earth's most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many years. For decades, scientists have known the inner core is solid thanks to ...

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 ...

The oceans are the largest entity on Earth’s surface. All that blue, however, may be dwarfed by an immense reservoir of hydrogen concealed in the planet’s heart. Experiments indicate that enough ...

Earth's core is mostly made of the metals iron and nickel, but it also contains lighter elements like hydrogen, oxygen and silicon. CharlesC via Wikimedia Commons under CC-BY-3.0 How Earth got its ...
