Earth's "impenetrable" radiation shield was breached from within during May 2024 solar storm
Research by Yoshizumi Miyoshi of Nagoya University and co-authors, using Japan's Arase satellite, points to electrons accelerating inside the barrier to multi-MeV energies
A barrier long thought to protect Earth's inner radiation zone from the most dangerous electrons was breached from within, according to a new paper in Geophysical Research Letters using data from Japan's Arase satellite during the May 2024 solar storm.
