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

The volume of the ocean, its average purity, and the chemical makeup of H₂O allow a simple estimate of the amount of hydrogen contained in all the water on Earth. These researchers show that hydrogen ...

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 ...

With an estimated 6 sextillion kilograms of the stuff—that’s 21 zeroes by the way—the Earth’s core is another example of why ...

For decades, many scientists believed that most of the water in our planet came from space, transported by meteorites and comets during the first moments of ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years. These ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. New research suggests Earth’s core may store up to 45 oceans’ worth of hydrogen, reshaping theories of water’s origin. (CREDIT: ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
