After decades of speculation, students at Warwick University have now found the first ever white dwarf pulsar. Since 1967's discovery of the first pulsar (a rotating star that emits electromagnetic radiation), scientists have only been able to find evidence of larger neutron stars as pulsars. For those of you who aren't astronomers, a neutron star is the last stage a celestial body goes through after a supernova before collapsing into a black hole. While scientists had yet to find any proof, many argued that the smaller dying white dwarf star could also become a pulsar. Now 50 years later, that theory has become fact.
