Astronomers study the oldest observable stars in the universe in much the same way that archaeologists study ancient artifacts on Earth. Here, Anna Frebel--who is credited with discovering several of the oldest and most primitive stars using the world's largest telescopes--takes readers into the far-flung depths of space and time to provide a gripping firsthand account of the cutting-edge science of stellar archaeology. Weaving the latest findings in astronomy with her own compelling insights as one of the world's leading researchers in the field, Frebel explains how sections of the night sky are "excavated" in the hunt for these extremely rare relic stars--some of which have been shining for more than 13 billion years--and how this astonishing quest is revealing tantalizing new details about the earliest times in the universe. She vividly describes how the very first stars formed soon after the big bang and then exploded as supernovae, leaving behind chemical fingerprints that were incorporated into the ancient stars we can still observe today. She shows how these fingerprints provide clues to the cosmic origin of the elements, early star and galaxy formation, and the assembly process of the Milky Way. Along the way, Frebel recounts her own stories of discovery, offering an insider's perspective on this exciting frontier of science. Lively and accessible, this book sheds vital new light on the origins and evolution of the cosmos while providing a unique look into life as an astronomer.
Die Galaxis hat riesige Imperien aufsteigen und fallen sehen. Jetzt hat sich die menschliche Zivilisation verstreut, und es gibt überall verborgene Schätze zu finden. Wenn man weiß, wo man suchen muss – wie Captain Rackamore und seine Crew. Der nächste Auftrag jedoch könnte sich für die Raumpiraten nicht nur als höchst lukrativ, sondern auch als äußerst tödlich erweisen ...
Ein neuer Blick auf alte Freunde Erstaunliche Dinge geschehen im Wald: Bäume, die miteinander kommunizieren. Bäume, die ihren Nachwuchs, aber auch alte und kranke Nachbarn liebevoll umsorgen und pflegen. Bäume, die Empfindungen haben, Gefühle, ein Gedächtnis. Unglaublich? Aber wahr! – Der Förster Peter Wohlleben erzählt faszinierende Geschichten über die ungeahnten und höchst erstaunlichen Fähigkeiten der Bäume. Dazu zieht er die neuesten wissenschaftlichen Erkenntnisse ebenso heran wie seine eigenen unmittelbaren Erfahrungen mit dem Wald und schafft so eine aufregend neue Begegnung für die Leser: Wir schließen Bekanntschaft mit einem Lebewesen, das uns vertraut schien, uns aber hier erstmals in seiner ganzen Lebendigkeit vor Augen tritt. Und wir betreten eine völlig neue Welt ...
NASA's first book on the Hubble Space Telescope marks the 20th anniversary of one of history's most important scientific tools. Here is Hubble's great visual legacy to humanity in stunning images that are benchmarks of astronomy and photography. Of the more than 100 classic Hubble images that were selected by NASA's experts, the 20 most significant are accompanied by commentaries by notable scientists. Veteran astronauts from NASA's five remarkable manned missions to maintain the telescope also contribute to this volume, making it an authoritative account of a magnificent scientific achievement. Beyond its scientific contributions, twenty years of Hubble research and imagery--ranging from our planetary neighbors to the edge of time and space--have had a profound impact on the world's imagination and spiritual growth, as documented in this inspiring book.
