Debra Fischer is a planet hunter who has discovered hundreds of worlds orbiting other stars, most of them gas giants, like Jupiter or Saturn. She is currently working to detect lower mass, Earth-like planets. Dr. Fischer’s most ambitious program is an intense search for rocky planets orbiting two of our nearest neighbors, Alpha Centauri A and B, being carried out in the Southern Hemisphere at Chile’s Cerro Tololo Inter-American Observatory. The project is also investigating whether conditions are right for the existence of life. Dr. Fischer, who was featured in Timothy Ferris’ PBS film, Seeing in the Dark, is a Professor of Astronomy at Yale University.
