Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...
The Sun constantly emits streams of charged particles, known as the solar wind, from its outer atmosphere, the corona. These particles travel throughout the Solar System and interact with Earth's ...
A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth's magnetic ...

Earth’s magnetic field nearly vanished in a terrifying close call
Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...
The Sun's warping of Earth's magnetic protections could explain how aurora occur in other parts of our solar system. Reading time 2 minutes Our Sun is a dynamic star, constantly bombarding our planet ...
