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.

The South Atlantic Anomaly (SAA) – likened by NASA to a 'dent' in Earth's magnetic field, or a kind of 'pothole in space' – generally doesn't affect life on Earth, but the same can't be said ...

South Atlantic anomaly As per NASA, the South Atlantic Anomaly arises from two main features—the tilt of the Earth and the flow of molten metals within its outer core.

A magnetic observatory is being re-established on South Georgia to provide vital data on the 'South Atlantic Anomaly' as scientists monitor a possible reversal of the earth's magnetic field.
