Happy birthday to #astrophysicist Jocelyn Bell Burnell! In 1967, as a grad student she discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. 🧪🐡👩🏼‍🔬🎢🔭 #histsci This radiation can only be observed when the star is pointed towards us;

My linocut print ‘Jocelyn Bell and the LGM-1’ showing the young astronomer in dark grey ink holding a sheet of paper, smiling while looking over her shoulder, dressed in a pea coat, cat’s eye glasses and pigtails. Behind her in green is her famous pulsar dataset like a series of horizontal parallel lines, each with an irregular peak in the middle, resembling a mountain range on a topographical map.
