This survey of astronomy begins here on Earth and heads outward to the ends of the observable universe. We will explore the Sun, the Moon, and the most interesting planets in our stellar neighborhood. Comets, asteroids, the Kuiper Belt, and the Oort Cloud are the next topics we will consider as we assess our solar-system environment. From our local solar system we then move to star formation and the nature of the Milky Way galaxy. Neutron stars, debris disks, supernovas, black holes, and dark matter follow.

Are we alone? How do you find an exoplanet? We will ask these questions as we study galaxies and cosmology: the expansion of the universe, dark energy, the Big Bang, wormholes, superstrings, and the possibility of other universes.
