Astronomy

Categories: Science | Astronomy
    • It is the oldest science
    • Explains the evolution of the universe
    • Amateur astronomers can play an active role in astronomy
    • The invention of telescopes evolved astronomy into a modern science
    • Often studied in conjunction with cosmology and/or areas of physics such as quantum mechanics.
    • Stargazers are actually looking at stars as they were years ago. It takes a long time for the light to reach Earth
    • People are actually made out of star remnants. Any atoms heavier than hydrogen have been expelled from supernovae.
  • 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.
