Dent on Earth’s magnetic field splitting in two, NASA warns of damage to satellites

A dent on the protective magnetic shield over the surface of Earth is widening. The dent is known as the South Atlantic Anomaly (SAA). NASA has said the anomaly is now growing and it can throw navigation in space out of gear. The magnetic field on which the dent has occurred protects the Earth from particle radiation of the Sun.

The weak spot is letting the harmful particle radiation from Sun come near to the surface.
