For as long as man kind has walked on earth, they've looked up at the stars in the dark night sky. Farmers have sown and harvest crops according to the phases of the moon. Explorers and sailors have charted their routes across the deserts, the forests, and seas, with the help of fast moving gas we call stars. The people who studied the stars were sometimes thought to be magical and wise. Even to this day, astronomy embodies both the practical and the romantic, the understdable and the mysterious.
