• Astronomy is the study of energy and the positions, dimensions, distribution, motion, and composition of matter in outer space. It also involves the evolution of celestial bodies and phenomena.
    1. It is the oldest science
    2. Explains the evolution of the universe
    3. Amateur astronomers can play an active role in astronomy
    4. The invention of telescopes evolved astronomy into a modern science
    5. Often studied in conjunction with cosmology and/or areas of physics such as quantum mechanics.
    6. Stargazers are actually looking at stars as they were years ago. It takes a long time for the light to reach Earth
    7. People are actually made out of star remnants. Any atoms heavier than hydrogen have been expelled from supernovae.
