2024 solar storm triggered ultrarelativistic electrons inside Earth's 'impenetrable barrier'

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.
