The CN Tower, one of the world’s tallest freestanding structures, stands as a testament to innovative engineering and meticulous construction. This video takes you behind the scenes to explore ...

This metallic inner core, about 1,500 miles wide, was discovered in the 1930s. Both the inner and outer cores consist primarily of iron and nickel.

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 ...

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.

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.

It is true that the outer core generates electrical currents that sustain the planet’s magnetic field, but Vidale says shifts in the Texas-size inner core are too minuscule to have an impact.

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

Earth’s inner core is changing shape, scientists have found. The discovery resolves a long-simmering controversy about what’s happening at the heart of the planet — which was long thought to ...

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.
