Researchers have documented surprising expansion of a weak spot in Earth’s magnetic field over the South Atlantic region. Satellite data indicates the anomaly has grown by an area equivalent to half the size of continental Europe in just over a decade, presenting new challenges for understanding our planet’s magnetic dynamics.

Mysterious Magnetic Weakness Expands Over South Atlantic

Earth’s magnetic field is developing a rapidly growing weak spot over the South Atlantic that has scientists concerned, according to new research published in a recent scientific journal. The phenomenon, known as the South Atlantic Anomaly, has expanded significantly over the past eleven years, with satellite data suggesting it has grown by an area equivalent to half the size of continental Europe.
