Constellations are random formations of stars that, when connected by imaginary lines, are seen as a picture.
The word “constellation” also refers to the area of the sky that is occupied by any of the 88 recognized constellations. Some constellations are modern, but most are ancient. In Greek mythology, for instance, Cassiopeia (kass-ee-oh-PEE-uh) was an overly proud queen. The gods chained her to a throne and condemned her to circle the North Star forever.
But constellations aren’t the only objects in the sky. From a backyard or sidewalk, anyone can see comets, shooting stars, human-made satellites, and much more. Telescopes bring many of these way-out sights to our eyes.
