2024 solar storm sent ultrarelativistic electrons through Earth's protective barrier
Original: 2024 solar storm triggered ultrarelativistic electrons inside Earth's 'impenetrable barrier'
The powerful solar storm of 2024 drove ultrarelativistic electrons deep into the Van Allen radiation belts, penetrating a region long considered an 'impenetrable barrier' that normally shields the inner belt from such energetic particles. Scientists say the event shows extreme space weather can reshape Earth's radiation environment in unexpected ways, with implications for satellites, astronauts and our understanding of how solar storms interact with the planet's magnetic field.
Why now: The finding reveals that even Earth's most robust radiation shield can be breached by a major solar storm, raising concerns for satellites and space infrastructure.
