The Orion Nebula is not to be confused with the Horsehead Nebula, also found in Orion, which is a faint nebula that resembles a horse’s head. Orion is a good constellation to mention when discussing colors of stars, which come in a range of colors hat are determined by temperatures. Because human eyes can’t distinguish color very well in dark environments, we often have difficulty differentiating stellar color and so most stars appear white. Betelgeuse, on the other hand, is also a supergiant star, but is in the class of coolest stars – those that are red.
