Pulsars are the compact remnants from explosions of massive stars. Some of them spin around their own axis hundreds of times per second, emitting beams of radiation into space. Until now, they could only be found through their pulsed radio emissions. Scientists at the Max Planck Institute in Hanover, Germany, using data collected by NASA's Fermi Gamma-Ray Space Telescope, have discovered a millisecond pulsar solely via its pulsed gamma radiation. The pulsar spins 390 times per second, emitting gamma-ray photons into space in the form of a beam, similar to a lighthouse. The novel gamma-ray analysis method developed by the Max Planck researchers has opened the door to an easier way of finding these elusive celestial objects.
