Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

Nearly 3,000 kilometers beneath Africa and the Pacific Ocean, two immense rock masses have been quietly influencing Earth’s magnetic field for millions of years. A new study, published in Nature ...

Scientists have spent decades cataloging life on Earth’s surface, from rainforest canopies to ocean trenches. But a growing body of research now shows that a vast, hidden biosphere thrives kilometers ...

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 ...

One of the strangest mysteries about our Earth is the presence of two dense, giant blobs inexplicably clustered above the planet's core. "These are not random oddities," says geodynamicist Yoshinori ...

Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we thought we knew about Earth’s past.

For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

Earth's magnetic poles flip in a process called a geomagnetic reversal. The planet's magnetic field is generated by chaotic flows of molten metal deep inside Earth's core.

Simulations suggest that two enormous masses of hot rock have been involved in generating Earth’s magnetic field and giving it an irregular shape ...
