Goldilocks and the Water Bears

'Highly recommended' Financial Times Today we know of only a single planet that hosts life: the Earth. But across a Universe of at least 100 billion possibly habitable worlds, surely our planet isn't the only one that, like the porridge Goldilocks sought, is just right for life?Astrobiologists search the galaxy for conditions that are suitable for life to exist, focusing on similar worlds located at the perfect distance from their Sun, within the aptly named 'Goldilocks Zone'. Such a place might have liquid water on its surface, and may therefore support a thriving biosphere. What might life look like on other worlds? It is possible to make best-guesses using facts rooted in science, and by studying 'extremophiles' - organisms such as the near-indestructible water bears, which can survive in the harshest conditions that Earth, and even space, can offer. Goldilocks and the Water Bears is a tale of the origins and evolution of life, and the quest to find it on other planets, on moons, in other galaxies, and throughout the Universe.

Our species has gone from fantasising about life on other worlds to actively looking for it - this book provides great background on clues scientists are using, and what makes the chase so exciting.

Vorwort
Across a Universe of at least 100 billion habitable, earth-like worlds, life cannot be restricted solely to the Earth. Or can it? Read this book to find out the hows and whys of astrobiology - the study of extraterrestrial life.

Autorentext
Louisa Preston is an astrobiologist, planetary geologist and unashamed lover of water bears. Her research focuses on places on Earth in which life is able to survive despite extreme conditions; such habitats provide clues on what alien life-forms might look like, and where we should search for them. Having worked on projects for NASA and the Canadian, European and UK Space Agencies, the only thing Louisa enjoys more than devising ways to find extra-terrestrial life is writing and talking about it. She has published numerous articles and academic papers, and regularly appears on radio and television shows, such as the BBC's The Sky at Night. She is a TED fellow, and spoke about the search for life on Mars at the 2013 TED Conference. Louisa has spent most of her life in one of two Londons - one in Ontario, and one in the UK - but she currently lives with husband, son and cat in Kent. Goldilocks and the Water Bears is her first book. @LouisaJPreston

Klappentext

'Highly recommended' Financial Times Today we know of only a single planet that hosts life: the Earth. But across a Universe of at least 100 billion possibly habitable worlds, surely our planet isn't the only one which, like the porridge Goldilocks sought, is just right for life? Astrobiologists search the galaxy for conditions that are suitable for life to exist, focusing on similar worlds located at the perfect distance from their Sun, within the aptly named 'Goldilocks Zone'. Such a place might have liquid water on its surface, and may therefore support a thriving biosphere. What might life look like on other worlds? It is possible to make best-guesses using facts rooted in science, and by studying 'extremophiles' - organisms such as the near-indestructible water bears, which can survive in the harshest conditions that Earth, and even space, can offer. Goldilocks and the Water Bears is a tale of the origins and evolution of life, and the quest to find it on other planets, on moons, in other galaxies, and throughout the Universe.
