The South Atlantic Anomaly
A weak spot in Earth's magnetic field causes strange phenomena and affects spacecraft.
The South Atlantic Anomaly
The South Atlantic Anomaly is a region where Earth’s inner radiation belt comes closest to the planet’s surface. It affects spacecraft, causes electronic malfunctions, and has been associated with unexplained phenomena including lights, temporal distortions, and compass anomalies.
The Science
Earth’s magnetic field dips in an area centered over Brazil, allowing charged particles to reach lower altitudes. The International Space Station experiences computer glitches passing through. The Hubble Space Telescope cannot take readings during transit.
The Phenomena
Beyond the scientific explanations, strange events occur in the region. Ships and aircraft report compass failures and electronic malfunctions. Crews describe unusual lights in the sky and water. Time seems to behave oddly, with clocks running slow or fast.
The Military Interest
The U.S. military closely monitors the Anomaly. Spy satellites are designed to shut down when passing through. Military flights report more unexplained radar contacts over this area than anywhere else on Earth.
The Expansion
Recent studies show the Anomaly is growing and may split into two parts. The region of magnetic weakness is expanding westward. The implications for electronics, radiation exposure, and the unexplained phenomena are uncertain.
Assessment
The South Atlantic Anomaly demonstrates that our planet contains genuine mysteries. While scientists explain the magnetic phenomena, the reported strange occurrences in the area suggest something more than mere radiation may be at work.
