Did you know...
... that today is Pulsar Discovery Announcement Day? In 1968,
Jocelyn Bell and Antony Hewish of Cambridge University in
England announced the discovery of pulsars, which were first detected on November 28, 1967, at the Mullard Radio Astronomy Observatory in Cambridge, England. Trivia buffs: they nicknamed that first signal LGM-1, for "little green men"
because the thought that the signals might be from another
civilization in outer space had crossed their minds!
