NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

Imagine waking up one morning to find your compass pointing in a completely different direction than the day before. That's essentially what's happening on a planetary scale as Earth's magnetic north ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study. Ancient ...

Scientists at NASA are closely monitoring a vast region of weakened magnetic intensity—known as the South Atlantic Anomaly (SAA)—due to the unique challenges it poses for satellites. From South ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

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 ...
