Andromeda is a large constellation in the northern sky, whose brightest stars complete the quadrilateral of Pegasus. It is easy to find in the sky because its brightest stars lie roughly on a straight line formed by the stars Alpheratz, Mirach, and Alamak. The star Algenib could also be part of this line, but it belongs to the constellation Perseus. To locate it, we can also use the fact that it lies south of Cassiopeia and borders closely on Pegasus—the line of 2nd magnitude stars leads from the northeast corner of the Pegasus square. The constellation lies just on the edge of the Milky Way and contains a number of interesting binaries of varying brightness, spacing, and color, as well as several clusters and nebulae. Galaxies of all types are not lost. The most famous, the Great Andromeda Nebula, which moves almost perpendicularly over our heads during early autumn evenings, is visible as a bright, hazy, elongated cloud just a short distance from the star ν Andromedae.
