Black holes, stars, newly discovered planets, extraterrestrial signals, dark matter and many more concepts keep some of our brightest scientists awake at night. From the origins of the universe to our latest theories, in this series, we venture into the fascinating world of the bright night sky.
Join our Garden Fellows as we unravel some of the most interesting questions behind those surprisingly simple to see, and yet complex, shiny dots in the sky.
Professor Sara Seager is a pioneer in vast world of exoplanets & the search for other life in the universe. In this Garden Talk, Sara will consider space science's biggest question: Are we alone in the universe?
