The anomaly detected in the South Atlantic Ocean originates from complex processes with the planet's outer core, as the movement of melting metals gives rise to the global magnetic field.

The South Atlantic Anomaly (SAA), a region of weakened magnetic field above Earth, poses a significant threat to satellites and astronauts. Increased radiation exposure within the SAA can cause ...

The South Atlantic Anomaly is an area where Earth's protective magnetic shield is at its weakest. This image was taken by the Doris instrument onboard the satellite known as Jason-1.

A century-old mystery of a stubborn cold patch in the North Atlantic is finally being unraveled. A new study links this anomaly to a long-term weakening of the Atlantic Meridional Overturning ...

Photo by ESA An unknown anomaly is causing the Earth’s magnetic force to weaken between South America and Africa, and scientists still aren’t sure why.

It’s called the South Atlantic Anomaly (SAA), and NASA is keeping a close eye on it. Stretching from South America across the Atlantic to Southwest Africa, this weakened zone in Earth's magnetic ...
