NASA is tracking the South Atlantic Anomaly (SAA), an unusual phenomenon in Earth's magnetic field. This region, characterized by a weakened magnetic field, has drawn scientists' interest and concern.

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.

Researchers have spotted interesting changes in the South Atlantic Anomaly, which is a region of Earth’s magnetic field that has a large dent. The area of weak magnetism appears to be splitting ...

The pigeons probably use tiny magnetic particles in their beaks to sense our planet's magnetic field, scientists say The birds use their ability to create a map of this field and ... ability to detect ...
