The nighttime sky is full of more than just stars and planets. If you are so lucky as to be in a location where the clear night sky is free from city lights, you must try to find the Andromeda galaxy. The best viewing times in the Northern Hemisphere are during the late fall, early winter months. First, look for a large rectangular box, which is the body of the flying horse, Pegasus. Viewing Andromeda is best when the Pegasus box is directly overhead. Second, look to the north (close to where the Big Dipper is often seen) to find the letter “W,” which is the Cassiopeia constellation. From Pegasus you will see a “V” of stars that extends from the box to the left of Cassiopeia. These are Pegasus’s rear legs, which overlap with the Andromeda constellation. The Andromeda galaxy lies just above the upper leg, directly between the Cassiopeia “W” and the Pegasus box. Look carefully at Figure 27.22 to help you pinpoint the exact location. With the unaided eye, it looks like small dim fuzz. You’ll see it best by not looking at it directly. The fuzz takes on more of an oval shape when viewed through a good pair of binoculars. What you see with the binoculars is mostly the central core. The full galaxy, visible only with more powerful telescopes (and time exposure), is about six times the diameter of the Moon!
