Satellites deployed by the U.S. National Aeronautics and Space Administration (NASA) have detected electromagnetic waves in space that sound eerily like the chirping of a flock of birds.
According to a recent paper posted to the website of Nature.com, a study conducted by NASA using its magnetospheric multiscale (MMS) satellites has detected rising-tone chorus waves about 1,000,000 km from Earth. Measurements by the MMS satellites identified discrete, rising-tone elements in the terrestrial neutral sheet, with frequencies frequently changing at a rate of about 100 Hz per second.
These wave-particle interactions and non-linear transfers within the chorus waves produce sounds surprisingly similar to the chirping noise made by birds during the early morning hours, NASA’s paper reports.
