This image was composed by combining 35 images of the stars in Orion. The red supergiant star in the upper left is Betelgeuse. It is a reddish color, because its surface temperature is much lower than the surrounding blue stars. The image was purposefully shown with blurred star trails in order to get more saturated colors and make it easier to see what color the stars are. The Horsehead Nebula is the reason for the pinkish tint under Orion's Belt, which is in the center of the image. In the lower right is the bright star Rigel. Our sun's temperature is not quite as cool as Betelgeuse, but not nearly as hot as Rigel; that is why it appears to be yellow.
