Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

While those characters may have discovered a beautiful and mysterious world deep down, a new study published in Nature Communications suggests that the Earth’s true core is probably just a 400 ...

The inner core is made from solid iron and nickel. In this diagram, the red lines represent the edges of the tectonic plates that make up the Earth's crust. For example, iron is mined from the ...

Earth's innermost layer is called the core. The outside of Earth's core is made from molten nickel and iron that can reach temperatures of 9,000 degrees Fahrenheit (5,000 degrees Celsius).

But we also don’t know a lot about the makeup of the planet itself, like how old the Earth’s core is. A new study may turn everything we think we know about the Earth’s inner core on its head.

By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...

Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

Physicists suggest a new explanation for the interesting properties of the Earth's inner core. Credit: NASA / Getty Images According to a new "holy grail" scientific discovery, the blazing-hot ...
