Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Ancient rocks show Earth’s magnetic field followed deep heat patterns inside the planet for hundreds of millions of years.

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.

Beneath Earth s surface, nearly 3,000 kilometers down, lies a mysterious layer where seismic waves speed up inexplicably. For decades, scientists puzzled over this D' layer. Now, groundbreaking ...
