This is because the internal solar environment plays an important role in determining the weather in space and also the Earth ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

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.

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly affect the ...

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...

As humans, we’re curious about how we got here. When we look out at the night sky, we see stars and planets, even galaxies.
