About this item

The science of finding habitable planets beyond our solar system and the prospects for establishing human civilization away from our ever-less-habitable planetary home.. Planet Earth, it turns out, may not be the best of all possible worlds - and lately humanity has been carelessly depleting resources, decimating species, and degrading everything needed for life. Meanwhile, human ingenuity has opened up a vista of habitable worlds well beyond our wildest dreams of outposts on Mars. Worlds without End is an expertly guided tour of this thrilling frontier in astronomy: the search for planets with the potential to host life. With the approachable style that has made him a leading interpreter of astronomy and space science, Chris Impey conducts readers across the vast, fast-developing field of astrobiology, surveying the dizzying advances carrying us ever closer to the discovery of life beyond Earth - and the prospect of humans living on another planet.
