Alien Earths

<p><b>Lisa Kaltenegger</b> is the Director of the Carl Sagan Institute to Search for Life in the Cosmos at Cornell University and Associate Professor in Astronomy. She is a pioneer and world-leading expert in modeling potential habitable worlds and their detectable spectral fingerprint. Professor Kaltenegger has served on NSF and NASA committees and is a Science Team Member of NASA's TESS Mission as well as the NIRISS instrument on the James Webb Space Telescope.<br><br>Professor Kaltenegger is the recipient of numerous international prizes and awards including being a European Commission Role Model for Women in Science and Research. She was named one of America's Young Innovators by <i>Smithsonian </i>Magazine an Innovator to Watch by <i>TIME</i> Magazine and stars in the IMAX 3D movie The Search for Life in Space. Asteroid Kaltenegger7734 is named after her.</p> <p>For thousands of years humans have wondered whether we're alone in the cosmos. Now for the first time we have the technology to investigate. The question should have an obvious answer: yes or no. But once you try to find life elsewhere you realize it is not so simple. How do you find it over cosmic distances? What actually is life?<br><br>As founding director of Cornell University's Carl Sagan Institute astrophysicist Lisa Kaltenegger built a team of tenacious scientists from many disciplines to create a uniquely specialized toolkit to find life on faraway worlds. In <i>Alien Earths</i> she demonstrates how we can use our homeworld as a Rosetta Stone creatively analyzing Earth's history and its astonishing biosphere to inform this search. With infectious enthusiasm she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview - planets covered in oceans of lava lonely wanderers lost in space and others with more than one sun in their sky! And the best contenders for Alien Earths. We also see the imagined worlds of science fiction and how close they come to reality.<br><br>We live in an incredible new epoch of exploration. As our witty and knowledgeable tour guide Professor Kaltenegger shows how we discover not merely new continents like the explorers of old but whole new worlds circling other stars and how we could spot life there. Worlds from where aliens may even be gazing back at us. What if we're not alone?</p> In the grand tradition of Carl Sagan and Neil deGrasse Tyson we now have a new tour guide to the cosmos. Professor Lisa Kaltenegger takes us along on the quest to solve one of the greatest mysteries of existence: are we alone in the universe? In <i>Alien Earths</i> Kaltenegger - one of the pioneers leading the way - reveals what we've already discovered and even more breathtakingly what we might find. The odds are overwhelming that something's alive out there. But will we ever see a sign of life on a planet circling a distant star? And if we do will we recognize it? This fascinating and tantalizing book points the way to YES. Do you want to prepare yourself for the next 'Copernican revolution'? Then read Lisa Kaltenegger's book! Fascinating. Effervescent with ideas and edge-of-your-seat discoveries <i>Alien Earths</i> provides a front-row seat to the astonishing era we live. Lisa Kaltenegger is an international leader in the discovery and analysis of exoplanets...Moreover she is a brilliant expositor. I eagerly await what will surely be a riveting book. Lisa Kaltenegger is in the best possible position to offer this timely and accessible overview of the rapidly evolving and exciting field of exoplanets expertly illuminating the questions we have begun to answer and the many that we can expect to be resolved in the years and decades to come. Linking our understanding of alien worlds (and the possibility of life) to the grand story of Earth's own past this is an engaging and personal book that couldn't be more up to date. Read ALIEN EARTHs and feel your cosmic perspective shift just a little on its axis. An erudite and highly readable inside view of the science and emerging discoveries of this remarkable new era.
