Researchers track slowly splitting 'dent' in Earth's magnetic field
Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field -- called the South Atlantic Anomaly, or SAA -- allows these particles to dip closer to the surface than normal.
