2024 solar storm triggered ultrarelativistic electrons inside Earth's 'impenetrable barrier'
Researchers say chorus waves boosted electrons to 5,000 times normal levels inside the Van Allen belts during the storm peak.

Earth’s “Impenetrable” Space Radiation Shield Was Just Breached From Within
Remember the big solar storm back in May 2024? The one that caused auroras as far south as Florida and Mexico? Scientists are still parsing out the impacts that storm had on the local environment, and a new paper published in Geophysical Research Letters by Yoshizumi Miyoshi of Nagoya University and his co-authors shows it might have allowed some nearby electrons to accelerate to relativistic speeds using something called a chorus wave.
2024 solar storm triggered ultra-relativistic electrons inside...
The Earth is surrounded by an invisible barrier that was thought to prevent highly energetic electrons from reaching closer to our planet. But in 2024, Japan's Arase space probe detected these electrons well inside the barrier. Now, research led by Nagoya University has found evidence that the electrons were accelerated locally rather than infiltrating from outer radiation belts. The Earth's magnetic field traps energetic charged particles, name…
Scientists thought that a natural barrier around the Earth prevented super-energy electrons from reaching areas close to it. But an extraordinary solar storm revealed a bigger surprise than just breaking into the barrier.

After the 2024 solar superstorm, the number of ultra-relativistic electrons behind the protective shield around the Earth has increased by about 5,000 times compared to the usual background level.
Earth's Radiation Barrier Broken by Historic Solar Superstorm
A powerful solar superstorm has exposed a remarkable weakness in one of Earth’s most mysterious natural radiation barriers. New satellite research has revealed that an extreme geomagnetic disturbance in May 2024 generated a massive concentration of high-energy electrons inside a region of near-Earth space previously thought to be virtually impenetrable. The measurements showed electron radiation […]
