Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size ...

Ample sunshine, ice cream, and afternoons at the beach might leave you wishing that summer would never end. Unfortunately, ...

This discovery suggests that all the siderophile elements – those that migrated to the core when the Earth was young and molten all the way through – are leaking out of the core. That includes ...

This discovery challenges the idea that Earth's core is completely isolated from the rest of the planet. Earth is composed of three main layers: the crust, the mantle, and the core.

Although more than 99.95% of Earth's gold is locked in the molten core, tiny amounts may be coming up to the surface in magma, a study found. A lava fountain at Kilauea in Hawaii is seen in early May.

While ¹⁰⁰Ru does exist in Earth’s mantle, it’s slightly more abundant inside of the core —alongside 99.999 percent of the planet’s gold and other precious metals.

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.
