People have been inventing constellations, shapes made by mentally connecting the astral dots, for at least 6,000 years. Celestial landmarks that have guided astronomers, farmers, and sailors for millennia, they offer simple, quiet pleasure to the rest of us as well. This collection of 48 Knowledge Cards presents a concise look at 46 star groups, with a constellation chart on the front of each card and its position, brightest star, visible constituent stars, zodiac sign, and origin notes on the back. One card is a glossary of astronomical terms and another gives a general overview of the heavens. A great way to learn to navigate the night sky, all in a deck the size of a pack of playing cards.
