Milky Way Through Summer Triangle - 1
The Milky Way passes through the center of the Summer Triangle. This asterism is defined by the three bright stars Altair, Deneb, and Vega, being the brightest stars in the three constellations of Aquila, Cygnus, and Lyra. During the summer months, the Summer Triangle is overhead around midnight from mid-northern latitudes. It is also visible during spring in the early morning, and during autumn in the evening sky. The dark rift running down the center of the Milky Way is due to interstellar dust in the plane of our Galaxy.
