Lisa Kaltenegger – Breaking the Wall to Thousands of New Worlds @Falling Walls 2014

BREAKING THE WALL TO THOUSANDS OF NEW WORLDS How Exoplanet Research is Scouting for Earth 2.0 Lisa Kaltenegger Associate Professor and Director of the Exoplanet Institute for Pale Blue Dots at Cornell University, Ithaca More than 2,000 years ago, the question whether we are alone in the universe was first asked. Today we live in a time when for the first time in history, we have the tools to answer it. Lisa Kaltenegger’s multi-award-winning research focuses on newly discovered planets outside our solar system, so-called exoplanets, and scouts them for biosignatures – the preconditions and indications of life. Her models combine data from remote planets with geographical and atmospheric data from Earth to determine how our planet would have looked billions of years ago using a technique called spectral analysis, which generates a spectral fingerprint of light for a planet. Kaltenegger was recently awarded 1 million dollars from the Simons Foundation which allowed her to start her own exoplanet research centre – the Institute for Pale Blue Dots – at Cornell University. Her team is using advanced computer models to map the light spectrum of more than 100 alien worlds that could potentially harbour different kinds of life forms. Besides inspiring a new era of astronomic discovery, this work could also “give us the opportunity to find out something about the evolution of the Earth, and perhaps even give a first glimpse into our future”.
