NASA scientists say a magnetic anomaly above our planet is going to split in half


TORONTO — NASA researchers have been tracking a strange new development in an already strange phenomenon: the dent in Earth’s magnetic field appears to be splitting in half. Yes, the Earth’s magnetic field has a weak spot, right over South America and the southern Atlantic Ocean, called the South Atlantic Anomaly (SAA). Currently, this anomaly does not impact us on the ground in any way. But when satellites pass through the anomaly, they have to account for extra radiation — and studying this so-called “dent” allows scientists to learn more about Earth’s magnetic fields and plan for future space missions and satellites.
