Look south to see Virgo, the second largest constellation in the sky (Hydra is the largest). Despite its size, Virgo can be difficult to recognize because it has few bright stars. It lies on the zodiac—the band of 12 constellations along the ecliptic—between the constellations Leo and Libra. Virgo’s brightest star, Spica, is at the base of a Y of seven stars that extends northwest toward Leo. A supercluster of galaxies sits on the border of Virgo and the constellation Coma Berenices about 20 degrees northwest of Spica. With a small telescope, the cluster can be seen as faintly glowing patches of light.
