The discoverers of the pulsar believed that these sounds – the message of extraterrestrial civilizations.
Employees of the Jodrell Bank Observatory observatory in honor of the 40th anniversary of the release of the album Unknown Pleasures of the British group Joy Division recorded the pulsar signals, the image of which can be seen on its cover. As specifies The Next Web, the observatory is located 23 kilometers from the Manchester studio of audio recording Strawberry Studios, where the group recorded the album.
On the front cover there is no name for the group and the album – only the image of the signal of the pulsar B1919 + 21, consisting of 80 wavy lines. Peter Saville – graphic designer and co-founder of Factory Records – designed the album cover based on the image that guitarist Bernard Sumner saw in the encyclopedia. He was first published in his dissertation by graduate student Harold Kraft in 1970.
B1919 + 21 is the first pulsar discovered by scientists. Pulsars are any source of radiation that periodically comes to Earth in bursts. Because of the same rhythm of signals, astronomers who discovered the B1919 + 21 in 1967, believed that it could be a beacon of extraterrestrial civilizations. Its first name was LGM-1 (Little Green Men – “little green men”). It was later established that B1919 + 21 is a rapidly rotating neutron star with a strong magnetic field.
Joy Division released the album Unknown Pleasures in 1979. When he quit, he was not a success, but later music editions named him the best post-punk album of all time.
