Scientists have made a shocking discovery – the Earth's magnetic field is weakening.

The magnetic field is vital for life on our planet, as it shields us from cosmic radiation and charged particles emitted from the sun. 

A large region of reduced magnetic intensity has been observed between Africa and South America, called the South Atlantic Anomaly, and it has formed a center of minimum intensity in just five years.

Researchers are speculating that the weakening is a sign that Earth is heading to a pole reversal, which is when the north and south poles switch places - and the last time this occurred was 780,000 years ago.
 
The anomaly is wreaking havoc on satellites and other spacecraft flying through the area, as many are experiencing technical malfunctions.
