This elective module provides a broad overview, accessible to non-scientists, of the nature of the stars, nebulae and galaxies that comprise our Universe, from our earliest thoughts about the nature of the cosmos to the latest results from observatories on the ground and in space. The module starts with an historical review of our changing understanding of our place in the Universe deduced from observations of the night sky. The properties of stars are discussed.
The various types of variable stars are presented and how they can be used to determine the distances to nearby galaxies. The life cycle of stars is discussed, from their formation to their eventual death leaving behind white dwarfs, neutron stars or even enigmatic black holes. Our own galaxy, the Milky Way, is explored and compared to other types of galaxies elsewhere in the Universe. The module concludes with a discussion of Cosmology and the Big Bang, outlining the whole history of the Universe from the beginning of space and time. The coursework assignments and observational project develop an appreciation for the role of astronomical observations in our understanding of the nature of the Universe.
