Crab Nebula

A composite image of the Crab Nebula showing the X-ray (blue), and optical (red) images superimposed. The size of the X-ray image is smaller because the higher energy X-ray-emitting electrons radiate away their energy more quickly than the lower-energy optically emitting electrons as they move.
