A rare type of white dwarf pulsar has been found for only the second time in history in research led by the University of Warwick in the UK and independently by the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany. To the great surprise of the scientific community, this odd pulsar phenomenon in a white dwarf was only observed for the first time in 2016. Only 773 light years away from Earth and spinning 300 times faster than our planet, the white dwarf pulsar has a size similar to the Earth, but a mass at least as large as the Sun. This means that a teaspoon of white dwarf material would weigh around 15 tons. A white dwarf pulsar consists of a rapidly spinning, burnt-out stellar remnant that lashes its neighbor – a red dwarf – with powerful beams of electrical particles and radiation, causing the entire system to brighten and fade dramatically over regular intervals. This is due to strong magnetic fields, but scientists are unsure what causes them.
