Nineteenth century astronomers saw a static, ancient sky that changed slowly, over millions of years. Only recently have we discovered how wrong that view was, and how dynamic the universe really is: exploding stars, colliding black holes, neutron stars spinning at thousands of times every second. No matter where we look, no matter how we look, we find a universe that changes and evolves on all time scales, down to nanoseconds. In this course we investigate the latest discoveries in transient astronomy, how these discoveries were obtained, and how future discoveries will be made.
