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 ...

Earth’s magnetic field feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...

A huge region of molten iron deep beneath the Pacific Ocean suddenly changed direction around 2010. The discovery suggests ...

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...

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 ...

Pigeons and other birds can do it. So can sea turtles and spiny lobsters, moths and mole rats, gray whales and big brown bats. Many members of the animal kingdom can detect the subtle undulations of ...

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 ...
