During the warm days of late summer, as the sky grows dark, the Milky Way galaxy can been seen as a faint glow across the top of the sky. Straddling the Milky Way, near the top of the sky, is one of the easiest asterism to find on the celestial sphere, the Summer Triangle.
The Summer Triangle is formed by three of the brightest stars in the summer sky, so it is easy to spot, even from a moderately light polluted sky. The three stars are Vega, brightest star in Lyra the Harp, Deneb, brightest star in Cygnus the Swan, and Altair, the brightest star in Aquila the Eagle.
If you live in a moderately light polluted area, and are not able to see the glow of the Milky Way, the Summer Triangle can be a guide post. While you might not be able to see the galaxy in all of its splendor, if you have a pair of binoculars or a small telescope, you can still scan the sky within the triangle and see the myriad stars the make up one of the inner arms of our galaxy. The area of sky between Vega and Deneb is also the direction we believe our Sun is traveling in as we make our way around the Milky Way.
