Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that ...

Key Takeaways on Earth's Inner Core Earth's inner core is solid and blistering hot. For decades, scientists have known ...

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really ...

Turbulent molten outer earth core The study indicates that the surface of the inner core is likely “undergoing viscous deformation” – essentially, it's changing shape at its boundary.

The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.

Earthquake data suggest that all or small patches of the inner core's surface may be swelling and contracting.

The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth.

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

Scientists found a rhythmic mantle plume beneath Ethiopia is slowly tearing Africa apart - hinting at the birth of a new ...

The Sun’s outer atmosphere—the corona—only reveals itself during total solar eclipses, which happen about every 18 months on ...

Such changes would make it difficult for life as we know it to survive on Earth. The increased heat and radiation would ...
