Use Cassiopeia to find Andromeda galaxy

Tonight … find the Andromeda galaxy, the next-nearest spiral galaxy to our Milky Way. Be sure to look at early evening, before the moon rises into your sky. But keep in mind that each following evening the moon will rise later, giving you more moon-free time for observation the Andromeda galaxy.

Many stargazers star-hop via the W-shaped constellation, Cassiopeia – shown on the chart above. As seen from the Northern Hemisphere on these November evenings, Cassiopeia appears in the northeast sky at nightfall and swings high to the north as evening progresses. It’s easy to spot, shaped like an M or W.
