When Jocelyn Bell Burnell and Antony Hewish discovered pulsars in 1967, they were baffled by the unnatural regularity of the radio transmissions. Jocularly suggesting that it was the work of extraterrestrials, they initially named their discovery as LGM-1 which expands to what?
PSR B1919+21 PSR B1919+21 PSR B1919+21 is a pulsar with a period of 1.3373 seconds and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell and Antony Hewish on November 28, 1967, it is the first discovered radio pulsar. The power and regularity of the signals were briefly thought to resemble an extraterrestrial beacon, leading the source to be nicknamed LGM-1 (for "little green men"). The original designation of this pulsar was CP 1919, which stands for Cambridge Pulsar at RA . It is also known as PSR J1921+2153 and is located in the constellation of Vulpecula. In 1967, a
Jocelyn Bell Burnell Jocelyn Bell Burnell Dame Susan Jocelyn Bell Burnell (; born 15 July 1943) is an astrophysicist from Northern Ireland who, as a postgraduate student, co-discovered the first radio pulsars in 1967. She was credited with "one of the most significant scientific achievements of the 20th century". The discovery was recognised by the award of the 1974 Nobel Prize in Physics, but despite the fact that she was the first to observe the pulsars, Bell was excluded from the recipients of the prize. The paper announcing the discovery of pulsars had five authors. Bell's thesis supervisor Antony Hewish was listed first,
