People have always sought to understand the stars. The journey begins when you go outside on a dear night and look up.
In ancient times, people saw stars as little more than ornamental lights affixed to the vault of the heavens. They arranged stars into sky pictures, or constellations, and gave names to the bright stars.
Ancient astronomers could hardly have guessed that stars generate light and energy deep in their cores by fusing hydrogen gas to form helium. Nor that these enormous spheres of hot gas are actually scattered throughout space.
