Cosmic Radio Waves Mimic Chirping Of ‘Alien Birds’
 

Radio astronomy deals with the detection and analysis of electromagnetic waves emitted by celestial objects in the frequency range from 100 to 100.000 MHz. The first cosmic radio source were discovered in 1931 by Karl Jansky, an American engineer from The Bell Telephone Company, who identified a faint signal from The Milky Way. The large development of radio astronomy grew up after World War II, as the technological progress allowed for the construction of sensitive and accurate radio telescopes. [Source]

Twin spacecraft have captured the clearest sounds yet from Earth’s radiation belts — and they mimic the chirping of birds.
NASA’s Van Allen Probes have been exploring the hostile radiation belts surrounding Earth for just three months. But already, they’ve collected measurements of high-energy particles and radio waves in unprecedented detail.
