The role of hydrogen in the evolution of galaxies (Free Astronomy Public Lectures)

Presented by Assoc Prof. Virginia Kilborn on 7th November 2014.

Hydrogen gas is one of the main components in a galaxy like our own Milky Way - but we can't see it when we gaze into the night sky. I will take you on a journey of the unseen parts of our Galaxy - and others like it - using sensitive observations taken with Australia's best radio telescopes. I will explain how astronomers use observations of hydrogen gas to determine the history, and predict the future, of galaxies in the universe.
