For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

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 surface of Earth's inner core may be shape-shifting ... elucidating its outermost layer. Since the first studies of the inner core in the 1990s found evidence of movement, there has been ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Led by Curtin University geologists Chris Kirkland and Tim Johnson, a research team unearthed this primeval crater beneath ...

These findings could lead to a better understanding of the inner workings of our planet and how life here will evolve over time. The Earth is made up of different layers. The outermost is the ...

This inner core is surrounded by a liquid outer shell of the same composition, enclosed by the mantle—a thick layer that begins about 30 kilometers beneath the Earth's surface and extends to a ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Earth's innermost layer is called the core ... of 9,000 degrees Fahrenheit (5,000 degrees Celsius). In the inner core, the pressure is so massive that the ultra-hot metal turns solid.

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

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