  • PH-104 Astronomy and Cosmology

    This module is a basic introduction to Observational Astronomy and Cosmology. It will be given in a non-mathematical style and is intended to inspire and motivate students of any discipline at an early stage in their studies. Opportunities will be given for making practical astronomical observations.
