As founding director of Cornell University's Carl Sagan Institute and author of the new ALIEN EARTHS: Planet Hunting in the Cosmos, Lisa Kaltenegger is one of the world’s most respected cosmologists. She believes that, with our revolutionary new cosmological technologies, we are likely to “discover” non-human life somewhere in the cosmos. What’s particularly astonishing about these kinds of conversations is how they no longer astonish us. Fifty years ago, the idea of discovering non-human life somewhere in the Universe was science fiction; today, it’s become the mainstream scientific assumption of leading cosmologists like Kaltenegger and the Harvard astrophysicist Avi Loeb. The issue is not if we’ll find these life-forms, Kaltenegger and Loeb are saying, but when. Astonishing.
Lisa Kaltenegger is the Director of the Carl Sagan Institute to Search for Life in the Cosmos at Cornell and Associate Professor in Astronomy. She is a pioneer and world-leading expert in modeling potential habitable worlds and their detectable spectral fingerprint. Kaltenegger serves on the National Science Foundation's Astronomy and Astrophysics Advisory Committee (AAAC), and on NASA senior review of operating missions. She is a Science Team Member of NASA's TESS Mission as well as the NIRISS instrument on James Webb Space Telescope. Kaltenegger was named one of America’s Young Innovators by Smithsonian Magazine, an Innovator to Watch by TIME Magazine. She appears in the IMAX 3D movie "The Search for Life in Space" and speaks frequently, including at Aspen Ideas Festival, TED Youth, World Science Festival and the Kavli Foundation lecture at the Adler Planetarium which was live-streamed to six continents.
