Beyond the edges of our solar system, astronomers have recently identified dozens of planets which could be like our own Earth—and potentially support extraterrestrial life. But how can we tell? Astrophysicist Lisa Kaltenegger explores how we can use our own planet and its wide range of species as a Rosetta Stone to detect signs of life on exoplanets. Join her for a journey over vast interstellar distances to answer an age-old question: are we alone in the universe?
