The James Webb Space Telescope has delivered its clearest view yet of a supermassive black hole's immediate surroundings, ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

A new study suggests lunar soil contains elements that solar wind transported to the moon from Earth’s atmosphere, solving a ...

A “natural history” approach to space exploration would take into account instead developments in the fields of physics, ...

They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

This superionic state of matter would neatly explain some unusual behavior in the core, such as the way it slows certain waves, and measurements that suggest it's squishy like butter rather than rigid ...

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 ...

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 ...
