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.

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 ...

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.

America is surrounded by a huge anomaly that is growing uncontrollably, and NASA is concerned. NASA has sounded the alarm and ...

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.
