A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes ...

Earth’s earliest crust may have looked a lot more like the continents we know today than scientists once believed. A recent study shakes up old ideas about how Earth's surface evolved, showing that ...

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 ...

The mystery of life’s beginnings has long captivated scientists. Central to that search is LUCA—the last universal common ancestor. LUCA sits at the root of the evolutionary tree, where two great ...

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.

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 ...

Proto-Earth is the term used to describe the earliest days of our planet, the body from which our pale blue dot evolved. At this stage of its geological evolution, it likely existed only for a ...

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 ...

The illustration shows a cutaway revealing the interior of early Earth with a hot, melted layer above the boundary between the core and mantle. Scientists think some material from the core leaked into ...
