About These Sounds
 Earth Screaming audio is a sample taking from the ESA web site. Earth can generate radio emissions in a natural way. The most intense of these emissions is a phenomenon called Auroral Kilometric Radiation (AKR). The radiation has a frequency of between 50 and 500 kHz and a total power of between about 1 million and 10 million watts. The sounds escape outward in space from the magnetic field lines. Some other planets emit cyclotron radiation too, AKR could be used to learn more about Jupiter, Saturn, Uranus and Neptune, and to detect extra solar planets.(Courtesy of Prof. D.
