The expanding universe was discovered at Mount Wilson almost 100 years ago. But there is something new! In the past 20 years, astronomers have found that cosmic expansion is speeding up, driven by a mysterious “dark energy” whose nature we do not understand. Dr. Kirshner, one of today's preeminent astrophysicists, is the recipient of many prestigious awards, including the 2014 Breakthrough Prize in Fundamental Physics (sponsored by Google, among others), as well as the 2014 James Craig Watson Medal of the National Academy of Sciences for “service to astronomy.”
