The term for a group of stars in the sky is called a constellation. Constellations are patterns formed by stars that are often associated with mythological stories, cultural symbolism, or recognizable shapes. Ancient civilizations relied on these star patterns for navigation, agriculture, and calendar-making. The International Astronomical Union (IAU) officially recognizes 88 constellations today, each with its unique configuration and history. Popular examples include Orion, Ursa Major, and the Southern Cross. Observing constellations can enhance our understanding of astronomy and our connection to the universe.
