The majestic twin tails of Comet Hale-Bopp. The ethereal beauty of a cluster of stars 50 light-years wide, wreathed in a cosmic cloud. The alien allure of the reddish deserts of Mars. These are some of the wonders of the universe captured by the cameras of talented amateur astronomers and NASA spacecraft -- some of them presented exclusively in this calendar. This 12-image collection was compiled by stargazing authority Terence Dickinson, author of NightWatch, who brings a wealth of practical experience to the calendar's daily diary of predicted celestial events, ranging from meteor showers to eclipses.
