For our February lecture, UCC Professor of Physics and Astronomy Dr Paul Callanan talked about those mysterious and exotic objects so fundamental to astronomy, black holes. The date was 10th Feb 2020.
Understanding the nature of black holes remains one of the great challenges of modern astronomy.
More than 100 years ago, Einstein produced a remarkable theory which could be used predict the basic properties of black holes, but it was only last year, in 2019, when we finally got a glimpse of what a black hole really looks like. Paul explored what we know about black holes, and what the most recent observations tell us about them.
