While many other images of the famous Crab Nebula have focused on the filaments in the outer part of the nebula, this image shows the very heart of the Crab Nebula including the central neutron star - it is the rightmost of the two bright stars near the center of this image. The rapid motion of the material nearest to the central star is revealed by the subtle rainbow of colors in this time-lapse image, the rainbow effect being due to the movement of material over time between one image and another.
