Lyra, the lyre, is a small but distinctive constelllation that is high overhead during summer and early fall evenings. It can be found by first locating blue-white Vega, one of the brightest stars in the sky at magnitude 0. Along with Vega, the main stars of the constellantion form a small parallelogram and a small equilateral triangle.
At the far corner of the triangle is epsilon Lyrae, commonly known as the "double-double star." Individuals with exceptional eyesight can just barely detect that epsilon is a double star without optical aid. Through a telescope with medium to high magnification, each of epsilon's two components is seen to be a close double star by itself.
Two other well-known objects in the constellation are Messier 57, the Ring Nebula, and T Lyrae, a very red carbon star.
