Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

(CNN) — Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

Using seismic waveform data, researchers believe they’ve discovered Earth’s even smaller inner core. The new inner core is made up of about 400 miles of dense iron, the researchers say. Seismic waves ...

An overview of the experimental setup at DESY in Hamburg reveals the vacuum chamber housing the high-temperature diamond anvil cell: The cell's orange colour comes from the light it emits at high ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

But the depth and inaccessibility of the inner core mean that uncertainties remain, she added. As for whether or not the debate about core rotation has truly ended, "we need more data and improved ...
