WINTER (Chart reflects January 1 at 10 p.m. from 40° latitude)
Despite the cold nights—which you should be prepared for—winter can be one of the best times for observing. The crisp, dry air is unusually transparent and the stars seem to shine brighter. The winter skies are dominated by Orion, one of the easiest constellations to identify and host to several sights on this list. The “W” of Cassiopeia is another prominent constellation; the Milky Way passes through it and you can find dozens of star clusters within it.
