Earth's Supposedly Impenetrable Radiation Barrier Has Been Breached - ScienceAlert — Satellite data uncovers a breach in Earth's inner radiation belt

Satellite data indicates that Earth's inner radiation belt has been breached. The Arase satellite discovered electrons moving faster inside the Van Allen belt, which contradicts earlier ideas about the belt's protection. This might influence space weather and satellite operations. The data indicates that killer electrons can break through a barrier thought to be unbreakable, so scientists need to update their models and safeguard satellites better.

“The data indicates that killer electrons can break through a barrier thought to be unbreakable, so scientists need to update their models and safeguard satellites better,” — Simone Whitfield, regional editor at Copley Field Staffing, commented.
