Far beneath Earth’s surface, two enormous structures lie hidden at the edge of the planet’s molten core. These formations, ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

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 ...

An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core.

With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

Two huge masses deep within Earth may have remained stable for billions of years, surviving the powerful churn of the interior, according to an analysis of seismic waves ringing throughout the planet.
