Researchers have spotted interesting changes in the South Atlantic Anomaly, which is a region of Earth's magnetic field that has a large dent. The area of weak magnetism appears to be splitting, and ...
For decades, we've thought we had a pretty good grasp of Uranus. The penultimate planet, our best measurements suggest, has a whole slew of idiosyncrasies. And one of the most puzzling is its magnetic ...
The European Space Agency's Swarm mission detected a large but temporary spike of high-energy protons at Earth's poles during ...
More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...
Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...
The Geotail mission launched in 1992 to study Earth's magnetosphere, but the satellite's future is now in doubt. Reading time 2 minutes For the past 30 years, Geotail has been sailing through the ...
An irreparable software glitch has put an end to Geotail, a JAXA-NASA joint mission. The satellite observed Earth’s magnetosphere for more than 30 years within an extremely elliptical orbit, but the ...
A massive disturbance in the solar wind caused Earth’s magnetosphere to fly without its usual tail. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...
The magnetic shield which surrounds Earth has weakened by an average of nine percent over the past 200 years, leaving experts baffled. One spot, in particular, has become extremely weak, known as the ...
