Black holes, stars, planets, meteor showers, comets and galaxies are just part of what the night skies have to offer. Stan Shadick explains all things celestial in this award-winning calendar that features star maps with horizon scenes for orienting novice stargazers to the heavens; inset maps illustrating planetary conjunctions and other events; and daily commentaries that describe constellation mythology, cosmic events and celestial discoveries. Find out what to watch for in the skies every night of the year. On a dark night, most of the stars described in this calendar can be viewed with the unaided eye or with binoculars. The "Skywatcher's 2009 Calendar" is the perfect way to explore the mysteries of the heavens.
