A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites ...

The South Atlantic Anomaly (SAA), a known region of Earth’s magnetic field weakness, has been under the observation of the ...

The weak spot, known as the South Atlantic Anomaly, was identified in the 19th century and expanded in recent years.

The Earth’s magnetic field has a giant weak spot roughly aligned with the south Atlantic, and 11 years of observations show ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

Earth's magnetic field is weakening and its north pole is shifting faster than previously observed, raising concerns about a potential geomagnetic reversal. Geomagnetic reversals, where the magnetic ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

The Moon's present lack of a global magnetic field contrasts with evidence of significant magnetization in lunar rocks and large surface regions, a long-standing scientific enigma. A new model ...
