Shedding light on jumbo Crab bursts

The Crab Nebula‘s pulsar, located 6,500 light-years away in the constellation of Taurus and formed in a supernova whose light is believed to have reached Earth in 1054, is among the brightest pulsars in the sky. Dr. Teruaki Enoto from the RIKEN Cluster for Pioneering Research and colleagues, tracking the Crab pulsar simultaneously with X-ray and radio telescopes, made fascinating observations published in the journal Science. “Out of more than 2,800 pulsars cataloged, the Crab pulsar is one of only a few that emit giant radio pulses, which occur sporadically and can be hundreds to thousands of times brighter than the regular pulses,” Enoto said. “After decades of observations, only the Crab has been shown to enhance its giant radio pulses with emission from other parts of the spectrum.”
