Constellations

Constellation is a group of stars that form a definite shape or pattern when viewed from the earth.

The uses of constellation in everyday life

1. Religious. In early days, people thought that the gods lived in the heavens and that the gods created the constellations. Many cultures believed that the position of the stars were their god's way of telling stories.
2. Agricultural. Before there were proper calendars, people had no way of determining when to sow or harvest except by the stars. Constellations made the patterns of the stars easy to remember
3. Navigation. One can figure out his or her latitude (North or South) just by looking how high Polaris (The North Star) appear in the night sky. This allowed the ships to travel across the globe.
