Topics which are covered include: the night sky; the nature of stars, their formation and life histories; light, atoms, and telescopes; binary stars and gravity; supernovae, white dwarfs, pulsars, neutron stars, and black holes; the structure and formation of the Milky Way, our home galaxy; interstellar matter; the nature of other galaxies and their origins; active galaxies and quasars; the large-scale structure of the Universe; the expanding universe, cosmology, the Big Bang, and the early Universe. The most recent results from space missions will be highlighted.
