Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

Think Earth is just a static rock ... "If true, the results suggest iron from the core has been leaking into the mantle for billions of years," Charles Lesher, lead author of the 2020 study ...

A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that the moon has a solid inner core, similar to Earth’s, composed of iron with a ...

The Keeble Observatory at Randolph-Macon College holds weekly public viewing during spring semester. Check their website ( or ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

This way prevented helium from escaping and allowed us to detect helium in iron.” This finding has implications for understanding Earth’s origins. The presence of helium in the core suggests ...

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.

This way prevented helium from escaping and allowed us to detect helium in iron." This finding has implications for understanding Earth's origins. The presence of helium in the core suggests the ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
