Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.
Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.
Ancient rocks show Earth’s magnetic field followed deep heat patterns inside the planet for hundreds of millions of years.
Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature.
"A strong magnetic field is very important for life on a planet." ...
The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...
Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.
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.
Advanced modeling has revealed an Australia-shaped magnetic anomaly beneath the country's Northern Territory that holds ...
Conventional air conditioners and refrigerators rely on vapor-compression cycles and chemical refrigerants that contribute significantly to global warming. Magnetic refrigeration offers a cleaner ...
