at the meeting of the american physical society in december 1933 (the proceedings were published in january 1934), walter baade and fritz zwicky proposed the existence of neutron stars, less than two years after the discovery of the neutron by sir james chadwick. in seeking an explanation for the origin of a supernova, they tentatively proposed that in supernova explosions ordinary stars are turned into stars that consist of extremely closely packed neutrons that they called neutron stars. baade and zwicky correctly proposed at that time that the release of the gravitational binding energy of the neutron stars powers the supernova: "in the supernova process, mass in bulk is annihilated". neutron stars were thought to be too faint to be detectable and little work was done on them until november 1967, when franco pacini pointed out that if the neutron stars were spinning and had large magnetic fields, then electromagnetic waves would be emitted. unbeknown to him, radio astronomer antony hewish and his research assistant jocelyn bell at cambridge were shortly to detect radio pulses from stars that are now believed to be highly magnetized, rapidly spinning neutron stars, known as pulsars.
