New research reveals that the Moon's core has a density similar to that of iron. This discovery may resolve long-standing ...

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

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

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external ...

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. It's believed to play an important role in maintaining the planet’s ...

The Keeble Observatory at Randolph-Macon College holds weekly public viewing during spring semester. Check their website ( or call the information line (804-752-3210) for dates and times.

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.
