South Atlantic Anomaly

The South Atlantic Anomaly is a place on Earth where magnetic fields get all mixed up and confused. The magnetic fields usually around the Earth are like a big blanket that protects us from harmful things that come from space, like radiation. But in the South Atlantic Anomaly, the magnetic fields get all wiggly and create holes in this blanket of protection. This makes it possible for more harmful things from space to reach the ground. Scientists are studying this anomaly so they can better understand how it affects our planet and how to keep us safe.
