Hi Gabe,

Ancient people decided that certain groupings of stars made pictures in the sky called constellations, which is based upon the Latin for "group of stars." Modern astronomers still refer to these groupings of stars, but the modern definition of a constellation is a bit different. On a modern star chart, astronomers divide the entire sky up into 88 regions. Each of these 88 regions contains one of the ancient constellations, as well as other objects that may not be visible to the naked eye.
