Study of celestial objects, space, and the physical universe.
For thousands of years, people have used stars to navigate. Sailors, explorers, and travelers could find direction by looking at star patterns like the North Star (Polaris), which sits almost directly above the North Pole.
By learning the positions of key stars and constellations, you can tell which way is north, south, east, or west—even without a compass!
Even today, knowing how to use the stars can help in outdoor adventures and emergencies.
Navigators in ancient times used the Southern Cross to find south in the Southern Hemisphere.
Backpackers can find north by locating the Big Dipper and following its 'pointer' stars.
