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.

Planet-hunter Debra Fischer explains that the secret to finding Earth-like environments beyond our solar system might require rethinking “Earth-like.” Tiny planets with tight orbits around dwarf stars may very well sustain rich life if their orbits fall within a “habitable zone.”
