The graph shows faint emissions from cold intergalactic dust, which rose to a peak in the middle of the Coma Cluster of galaxies as ESA's Infrared Space Observatory scanned across it. ISO followed the two slanted lines across the image. Both measurements gave similar results, which have been averaged to show the signal more clearly.
