A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new research has presented experimental evidence confirming a previously theorized ...

Our magnetosphere plays the role of gatekeeper, repelling unwanted energy that's harmful to life on Earth, trapping most of it a safe distance from Earth's surface in twin doughnut-shaped zones called ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

Mars is the next big frontier of human space exploration, but it’s hardly a hospitable world. While there have been many proposals for making the Red Planet a bit more cozy, NASA scientists have now ...

Earth's protective magnetic shield has a weak spot, the South Atlantic Anomaly, which is expanding and splitting. This anomaly, driven by changes in Earth's core, poses risks to satellites and ...
