Volunteers discover rare space weather events using their ears

Scientific Discovery/Space Weather

Scientists are using a citizen science project called HARP to study space weather by translating Earth's magnetic field measurements into sound. Volunteers discovered an unexpected pattern in plasma waves from NASA's THEMIS mission, noting that some waves exhibited lower pitches near Earth and higher pitches farther away, which aids understanding of geomagnetic storms.
