NASA scientists have been tracking a strange “dent” in the Earth’s magnetic field as it slowly moves westwards over South America and the southern Atlantic Ocean.
The Earth’s magnetic field is what protects us from highly charged particles arriving to our planet from the Sun, known as solar winds.
But scientists have noticed that this effect weakens significantly in a specific area above the South Atlantic. While this are, which has been known for a while now as the “South Atlantic Anomaly” (SAA), researchers are now observing that the region is moving westwards — an even splitting into two lobes, according to a NASA statement.
