The Radio Sky: Tuned to 408MHz

This image maps the entire sky at 408 MHz, a frequency between US broadcast television channels 13 and 14. In the 1970s, large radio telescopes at Jodrell Bank, MPIfR, and Parkes Observatory collaborated to create this map. At this frequency, cosmic radio waves are generated by high-energy electrons spiraling along magnetic fields in interstellar space.
