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.

The Earth’s magnetosphere is a protective shroud that blocks charged particles and cosmic rays blasted out by the Sun. The ...

A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma. Because Earth possesses an intrinsic magnetic field, the planet is ...

NASA has released the clearest images ever compiled of Earth’s magnetosphere radiation belt. But the spacecraft that accomplished the feat wasn’t only designed to detail the vital atmospheric region ...

Earth is constantly being hammered by charged particles emitted by the Sun that have enough power to make life on Earth almost impossible. We survive because Earth’s magnetic field traps and deflects ...

A strange phenomenon native to the Sun’s environment was spotted in the Earth’s magnetosphere, likely evidence of reactions ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New satellite data and advanced simulations show that the morning side of 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 ...

Quasiperiodic (QP) very low frequency (VLF) emissions are intermittent bursts of electromagnetic energy, observed in the frequency range of approximately 3–30 kHz, that recur at quasi-regular ...
