Chorus waves, linked to auroras, have been found far beyond Earth, at approximately 165,000 kilometers from our planet. Initially thought to be confined within the influence of Earth's magnetic field, these waves can accelerate dangerous particles like killer electrons at unprecedented distances. This discovery, made by a team led by Chengming Liu using NASA's MMS mission, raises new concerns for the safety of interplanetary travel, indicating that these potentially harmful phenomena are more widespread in deep space than previously understood.
Chorus waves, previously thought to be limited to near-Earth regions, have now been identified at vast distances in deep space, posing potential risks for interplanetary missions.
These chorus waves, named for their resemblance to birdsong, accelerate dangerous high-speed particles known as killer electrons, significant for the safety of spacecraft and astronauts.
