Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Two enormous structures that sit at the border between the Earth’s mantle and its core have puzzled scientists for decades, defying reigning theories of how our planet came to be. In a new study ...

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.

Scientists have made a groundbreaking discovery that challenges our understanding of Earth’s structure: an ocean located deep within the Earth’s mantle. This hidden reservoir could rival the volume of ...

Scientists find that deep molten rock can power long-lasting magnetic fields, helping large rocky planets hold onto their ...

Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity provinces, or LLVPs, stretch beneath Africa and the Pacific. They are so ...

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

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New ...

Scientists have discovered a heartbeat-like pulse emanating from inside the Earth beneath the continent of Africa, which they believe will one day rip the continent into pieces. In a new study ...
