APOD 3.1 The Hunter's Stars

The Hunter's Stars


This image was interesting to me because of a) its recognizable-ness, and b) because you can actually see the colors of the different stars. Most times it seems as if the stars in the sky all have the same whitish, yellowed hue even though in reality they can be red or blue as well. In the constellation Orion there are a red and a blue star, named Betelgeuse and Rigel respectively. Betelgeuse is a red giant star and Rigel is a a blue supergiant- making it seem even more incredible to be able to determine their colors with the naked eye. What appears to be another star here is the light red glow in Orion's belt. This 'star' is actually the Orion nebula and is also seen easily with the naked eye. So overall this picture is not incredibly fascinating by itself, but the concept behind the subject matter is.
