Both the Crab Nebula and Crab pulsar are clearly visible in these images of the Crab nebula taken by the ROSAT High Resolution Imager (HRI) (left) and the Chandra X-ray Observatory's Advanced CCD Imaging Spectrometer (ACIS) (right). The supernova precursor to these objects was observed by Chinese astronomers in the year 1054. The pulsar (the bright compact emission) produces highly relativistic electrons which themselves produce synchrotron radiation in the magnetic field of the nebula.
