As darkness falls on these balmy August evenings the famous "Summer Triangle" is high in the southeastern sky. This seasonal triangle is composed of three of the brightest stars in the night sky, each of which is the brightest star in its own constellation. Lyra, the Small Harp, lies high in the late evening sky. Its main star is the great Vega, one of the brightest in the sky. Look for Lyra by locating Vega and then the parallelogram of stars nearby. The great constellation Cygnus, the Swan, flies high through the August night. Using bright Vega as your guide star, look for the cross just to the east. Cygnus is also known as the Northern Cross. Deneb, the Swan's tail, is a supergiant star. If Deneb replaced the Sun in the center of our solar system, it would engulf Mercury and Venus. Aquila, the Eagle, was known to the ancient Greeks as the great bird of Zeus. Altair, the brightest star in Aquila, is only 16 light-years from Earth. The bright stars of the summer night, Vega, Altair, and Deneb, make up the Summer Triangle. Seek out the celestial treasures within the "Summer Triangle". Stay Tuned!
