Beschrijving uitgever
One of the world’s leading astrobiologists takes us on an awe-inspiring journey across the cosmos to investigate some of humanity’s most profound questions: Are we alone in the universe? And, how did life on Earth begin?
We are in a golden age in astronomy, living on the cusp of breakthroughs that will revolutionize our understanding of our place in the cosmos in. Yet a profound question remains: Are we alone in the universe?
We have never been closer to answering this question. In The Secret Life of the Universe, astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie A. Cabrol takes us to the frontiers of the search for life. The book’s odyssey begins by exploring how life began on Earth in order to understand what’s necessary for its existence elsewhere. What role did our Moon play? And could life on Mars have seeded life on Earth?
Cabrol continues this dazzling interplanetary tour, illuminating the likeliest places for life in our neighborhood: While Mars and the icy moons of Jupiter and Saturn are among the top contenders, recent missions are redefining the limits of habitability to include unexpected worlds. Finally, we seek life beyond our Solar System, becoming witness to a revolution in the night sky: the realization that there are as many planets as stars in our galaxy. With more than 300 million exoplanets in the habitable zone of their stars in the Milky Way alone, to think we are alone, or the only advanced intelligent civilization, may be little more than nonsense.
The Secret Life of the Universe is a comprehensive and authoritative guide to the search for life. This is an exhilarating journey for anyone who has ever looked up at the stars and wondered what might be out there.
PUBLISHERS WEEKLY
This stimulating survey from Cabrol, director of the Carl Sagan Center at the SETI Institute, details how she and other scientists search the cosmos for extraterrestrial life. Cabrol offers insight into what kinds of planets are most likely to harbor life by outlining theories for how life emerged on Earth, with some scientists claiming that the first organisms developed from alternating periods of dryness and wetness around volcanic hot springs, while others believe that reactions among RNA molecules in ice constitute a more likely genesis. Elsewhere, Cabrol notes that one study has detected phosphine, a compound "only produced by life on Earth," in Venus's atmosphere, and that geysers on Saturn's moon Enceladus suggest the planet has a mantle composed of water. Cabrol has a talent for making technical research accessible for general readers and serves up a bounty of fascinating trivia, pointing out that "rogue planets" wander the universe after getting "ejected from their parent systems" and that the exoplanet 55 Cancri e has a 2,700ºC surface "where gases behave almost like liquids."
