The mechanisms underlying two important phenomena in the Archean—the emergence of continental crust and the presence of an exceptionally strong geomagnetic field—remain poorly understood. Notably, ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has ...

Earth’s magnetic field is easy to forget. It doesn’t make noise, it doesn’t flash, and it doesn’t ask for attention. Yet it ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own planet, not even making it through the thin crust. Roughly 3,000 ...

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.

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

Far below the deepest boreholes, Earth’s core appears to keep its own rhythm, a slow magnetic throb that repeats roughly ...

Andrew Biggin receives funding from the Natural Environment Research Council. While we have sent probes billions of kilometres into interstellar space, humans have barely scratched the surface of our ...
