Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

Antennas installed at 18 U.S. high schools detected bursts of radio activity that can precede solar disturbances capable of ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

Earth’s magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, according to a NASA-led study, pointing to a deep-Earth process that could knit ...

For the prototype superconducting dipole magnet of the collector ring for Gesellschaft für Schwerionenforschung, Germany, the thermal radiation from outside would be shielded by the thermal shield (TS ...

A passive superconducting shield was proposed earlier to realize a high-field (3-4 T) septum magnet for the Future Circular Collider. This paper presents the experimental results of a potential shield ...

New NASA research demonstrates that 540 million years of Earth’s magnetic field changes have corresponded to surface ...
