Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

A NASA fleet has spotted the first magnetic switchback near Earth, a zigzag in the magnetic field at the edge of our planet’s shield. The result shows that twists once seen near the Sun also appear in ...

On Dec. 17, the National Centers for Environmental Information (NCEI) and the British Geological Survey (BGS) released an updated version of the World Magnetic Model, a prediction for how Earth's ...

Ancient bricks may be key to understanding Earth’s variable magnetic fields. Scientists examined the iron oxide levels of 3,000-year-old bricks to understand the level of magnetism the bricks were ...

There is wide consensus among climate scientists that the Earth is warming and that humans directly contributed to this change by burning fossil fuels. Pole reversals have occurred several times in ...

One of Earth’s deepest mysteries lies beneath our feet: the planet’s inner core. Made of iron and nickel, the hot, solid sphere is about 70% the size of the moon. Recent research suggested this dense ...

A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant waves. Tsunamis generate magnetic ...

The north magnetic pole’s observed locations from 1831–2007 are yellow squares. Modeled pole locations from 1590–2025 are circles progressing from blue to yellow. Credit: National Centers for ...

Picture yourself standing at the Geographic North Pole with a compass in your hand. You'd expect that trusty needle to point ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
