Magnetic anomaly of the Earth expands to South America: NASA alerts on its possible consequences

An anomaly in the magnetic field of the Earth, known as the anomaly of the South Atlantic (AAS), is experiencing an expansion to South America, according to recent NASA observations, which has monitored it since 1958.

The AAS, a region with reduced magnetic intensity between South America and Africa, is generating concern among NASA scientists, the US National Intelligence Agency (NGA) of the US and the United Kingdom Defense Geographic Center (DGC), due to its growing weakness and its potential impact on space and terrestrial technology.

Impact and mysteries:

The Earth’s magnetic field acts as a shield against solar wind and radiation. In the AAS, this protection is lower, which affects satellites and spacecraft that orbit the earth. Although it has been studied for decades, the exact origin and consequences of the AAS are still research.

NASA compares the AAS with a «aboller» in the magnetic field, and its study is crucial to protect space technology and understand this complex phenomenon. Recent research has revealed that AAS also influences terrestrial auroras.

Expansion and monitoring:

In the last four years, the AAS has shown a 7% increase in its weakness over South America. NASA and other agencies continue to monitor anomaly for more information and mitigate possible risks.
