Constellations: These groups of stars that form patterns are called constellations., The stars in a constellation are often connected by imaginary lines to make the pattern easier to see. For example, one famous constellation is Orion, which looks like a hunter., Orion’s belt is made of three stars in a row. Some people imagine that Orion, the hunter, is followed by his dog (another constellation called Canis Major) and that they are fighting a bull (a constellation called Taurus)., International Astronomical Union (IAU), Different cultures had their own ways of naming and defining these constellations, so to keep everything organized, an international group called the International Astronomical Union (IAU) decided on official boundaries for 88 constellations., The entire sky is divided into 88 regions, each named after a constellation., In the night sky, there are two famous star patterns called the Big Dipper and the Little Dipper., These patterns are part of larger constellations, with the Big Dipper being part of Ursa Major and the Little Dipper part of Ursa Minor., A special star called the Pole Star, or Polaris, is part of the Little Dipper. This star is unique because it stays in the same spot in the sky, always pointing North. This makes it useful for finding the North direction, especially in the Northern Hemisphere., In India, the Big Dipper is known as Saptaṛiṣhi, and the Pole Star is called Dhruva tārā., These patterns and stars have different stories and meanings in various cultures., some tribes in Central India see the four main stars of the Big Dipper as a “grandmother’s cot,” with the other three stars representing thieves trying to steal it..
