NASA has taken it seriously as this unique phenomenon will finally result in weakening the earth’s magnetic field and eventually affects the protective field that shields us from solar flares, and disrupts satellite communication. Already, over South America and the southern Atlantic Ocean, this unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows ...
