Astrophysics, Astrochemistry and Astrobiology

Module code: NT2001

This module examines one of the greatest questions mankind has ever asked: are we alone? It is only recently that humanity has started to gain the tools that will allow a rigorous scientific analysis of the issues involved in the search for life in the Universe.

Not one person you encounter can be considered an expert in the whole field; only in recent years have specialist astrobiologists emerged, and they certainly don’t all agree on all the answers. With your experience across the sciences and in interdisciplinary thinking you will be well placed to tackle the questions presented by this module.
