Chorus Waves Detected Far Beyond Earth's Magnetosphere

New research reveals these mysterious space radiation bursts can form in deep space, challenging previous theories and raising safety concerns for space travel.

Chorus waves, bursts of radiation resembling birdsong, have been detected up to 165,000 kilometers from Earth, far beyond previously known regions.
Previously believed to form only near planets with dipolar magnetic fields, the waves have now been observed in regions where such fields are absent.
These waves are linked to the acceleration of high-energy electrons, or 'killer electrons,' which can pose risks to satellites and astronauts in space.
The discovery could improve understanding of space weather, aiding in the prediction and mitigation of radiation risks for future interplanetary missions.
The findings suggest chorus waves could form anywhere in space with a magnetic field, expanding their potential impact on both scientific research and space travel safety.
