A study of how we know what we do about the planets, stars and galaxies, and an understanding of how the study of astronomy requires the application of physics.
We will begin by studying the ways in which humans have studied the sky from ancient Greece, China, Egypt and India, to Copernicus, Galileo and Newton, while learning of the various conclusions, inaccuracies and later day advancements that set astronomy on more solid ground. You will learn about planets, moons, asteroids and comets that are part of our solar system. We then take a look at spectroscopy which has helped understand the birth and death of stars, the interstellar medium and supernovae. Galaxies, the building blocks of the universe, is our next destination: the big bang, the formation of matter, then galaxies and dark energy and matter. And finally, we think about worlds beyond our own, and the hunt for exo-solar planets, signatures of life and space missions of the past.
