An already gigantic hole in Earth’s natural force field has grown by nearly half the size of Europe in 10 years, according to a new study.

The Earth is protected by the cosmic equivalent of cling film called the magnetic field , generated by swirling iron currents in the liquid outer core.

The magnetosphere protects us against dangerous galactic and solar rays , yet it has been weakening by about 10% over the last 200 years or so.

Adding to the strangeness is the South Atlantic Anomaly , a roughly 4.3million square mile-sized magnetic weak spot.

Discovered in 1958, the region stretches from South America across the southern Atlantic Ocean toward southwestern Africa.
