NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...

It is this magnetic field that has recently got NASA scientists on high alert following the identification of a 'dent' in the ...

Earth’s magnetic north pole is on the move—and in surprising ways. With the release of the World Magnetic Model 2025, ...

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 ...

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.

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 ...

As of Jan. 16, the megaberg, known as A23a, is roughly 180 miles (290 kilometers) away from South Georgia and the South ...

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 ...

NASA is closely monitoring the South Atlantic Anomaly, which is a growing dent in the Earth's magnetic field that allows charged solar particles to approach the surface. A huge 'dent' anomaly in the ...

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.
