A massive and evolving weak spot in Earth’s magnetic field, known as the South Atlantic Anomaly (SAA), has caught the ...

This vast, developing phenomenon, called the South Atlantic Anomaly, has intrigued and concerned scientists for years, and perhaps none more so than NASA researchers. The space agency's satellites and ...

As of Jan. 16, the megaberg, known as A23a, is roughly 180 miles (290 kilometers) away from South Georgia and the South Sandwich Islands, according to location coordinates from the U.S. National Ice ...

South Atlantic anomaly As per NASA, the South Atlantic Anomaly arises from two main features—the tilt of the Earth and the flow of molten metals within its outer core.

NASA is observing an anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the ...

This phenomenon, dubbed the South Atlantic Anomaly (SAA), is of concern to researchers since it poses challenges for satellites and spacecraft and raises questions about the uniformity of our ...

NASA is keeping an eye on a massive “dent” in Earth’s magnetic field that could put an end to humanity as we know it.

Stretching over South America and the southern Atlantic Ocean, the South Atlantic Anomaly is a dent in Earth’s magnetic field, allowing particles from the Sun to penetrate closer to the planet.

An curved arrow pointing right. The closest radiation belt to Earth roams above South America. It is called the South Atlantic Anomaly and gives off high levels of radiation that has been known to ...

A magnetic observatory is being re-established on South Georgia to provide vital data on the 'South Atlantic Anomaly' as scientists monitor a possible reversal of the earth's magnetic field.

The region, known as the South Atlantic Anomaly (SAA), spans more than more than 4.3 million square miles over parts of Africa and South America and is moving westward. The 'dent' allows harmful ...
