High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective ...

Barreling through the universe with incredible power and speed, galactic cosmic rays are a major source of radiation in space. But thanks to Earth’s strong magnetic field, these charged particles ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

Two vast, mysterious blobs of hot rock around Earth’s core may have been instrumental in producing Earth’s magnetic field and caused it to be slightly wonky for millions of years. Scientists have ...

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 field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

A team of geologists found for the first time evidence linking regions of low seismic velocity and the shape of the Earth’s magnetic field. A team of geologists has found for the first time evidence ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

For all we’ve learned about places far away in outer space, we may have barely scratched the surface of the places lying deep within Earth. As a result, there’s a lot of information we seem to be ...
