Do you see the horse? Neither do I.
This is the Blue Horsehead Nebula in Scorpius (not to be confused with the Horsehead Nebula in Orion, which is the star of many Hubble images.) It's been photographed in infrared, so it's no longer blue, or anything resembling a horse's head. But it's a fair tradeoff to get to see those colors.
