From the explanation
“Tune your radio telescope to 408MHz (408 million cycles per second) and check out the Radio Sky! In the 1970s large dish antennas at three radio observatories, Jodrell Bank , MPIfR , and Parkes Observatory , were used to do just that – the data were combined to map the entire sky.”
