Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

NASA launches TRACERS satellites to reveal how solar energy penetrates Earth's magnetic shield and triggers space storms.

Abstract: Most magnetic shielding rooms (MSRs) are made of highly permeable permalloy. The limitation of such MSR is its intrinsic magnetic noise, which exceeds the sensitivity of magnetic sensors, ...

A radio signal has been detected, pointing to the possible existence of a magnetic field on YZ Ceti b, an exoplanet 12 ...

Solar flares and other activity can disrupt radio communications, power grids and navigation signals, according to NASA.

Abstract: A magnetic field measurement with enhanced sensitivity based on the Vernier effect of a dual-loop optoelectronic oscillator (OEO) using a cascaded giant magnetostrictive material-fiber Bragg ...

Learn more about magnetic “switchbacks,” an odd magnetic twist that wasn’t expected to happen so close to home.

Earth’s magnetic bubble, the invisible shield that normally deflects charged particles from the Sun, briefly shrank to a ...
