The light in the band of Milky Way originates from un-resolved stars and other material that lie within the galactic plane of our galaxy. b. Dark regions within the band of Milky Way correspond to areas where light from distant stars is blocked by interstellar dust. There are 88 official constellations that cover the entire sky. c. Winter Triangle is an asterism. The brightest stars in a constellation or an asterism all lie at about the same distance from Earth. d. The stars which are at close angular distances to one another in the sky e. g. the three stars in the Orion's belt: Alnitak, Alnilam and Mintaka, must actually be in close physical proximity to each other and, therefore, at about the same distance from Earth.
