    The pro-American analogy can be stretched further. The patriotic part is all false colors, red and blue just painted onto shocked and superheated intracluster gas. The red is from electrons frantically spinning in magnetic fields while the blue is thermal emission from hot gas. Nothing but hot air (so to speak).
