The Crab Nebula is the result of a supernova observed by Chinese astronomers in 1064, making it one of the more recent remnants available to study. Its core contains a rapidly spinning pulsar, which helps power a shockwave that produces emissions that run from the infrared, across the visible, and into the gamma-ray portion of the spectrum.
But over the last few years, several of these observatories have picked up sudden surges in the nebula's output that hint at electrons traveling with energies of a Peta-electron Volt.
