Astronomers of Australia’s Commonwealth Scientific and Industrial Research Organisation made the pulsar-pounding, asteroid-zapping discovery while using the Parkes Telescope to study the dusty, high-radiation environment surrounding the tiny spinning husk of the dead star. Pulsars are spinning compact stellar objects known as neutron stars that generate powerful beams of radiation from their intensely magnetized poles that, if aligned correctly with Earth, can be observed as ultra-precise radio pulses.
