For 540 million years, Earth’s magnetic field and atmospheric oxygen levels have danced in sync — and NASA scientists just ...

Researchers have found evidence that Earth's core is leaking gold and other precious metals, according to a new study. The vast majority (99.9%) of Earth's gold and other precious metals are ...

New simulations reveal that an ancient ocean of magma located above the Earth's core continues to shape the planet's ...

As meteorites bombarded one another in Earth’s early history, a reservoir of these precious metals developed when the core formed about 4.5 billion years ago.But this study suggests that at ...

Earth’s core has two layers. A hot, solid metal sphere of iron and nickel is roughly 70% the size of the moon, with a radius of about 759 miles (1,221 kilometers).

Scientists discovered the true age of Earth's core, and it's older than they thought. Over the years, approximations for our planet's inner core have been all over the board, but most recently ...
