Although this image is very noisy, it shows a strange view of this familiar galaxy in Hydrogen Alpha. The halo of the galaxy is invisible and the core is dimmed. Both these regions are populated by older stars. Bright spots in the arms of the galaxy show more violent star forming regions rich in hydrogen alpha emission.
