En octubre de 2017, científicos del observatorio Haleakala, en Hawái, detectaron un objeto interestelar en movimiento próximo a la Tierra. Primero fue catalogado de cometa, pero esta hipótesis fue descartada. Llamado "Oumuamua", "mensajero" o "explorador" en hawaiano, finalmente fue catalogado como asteroide, si bien su forma y su comportamiento diferían del resto de los asteroides y cometas de nuestro sistema solar. Cuanto más lo observaban los científicos, más extraño les parecía.

Lleno de anécdotas divertidas, Neil deGrasse Tyson explica con claridad qué son las estrellas enanas, los agujeros negros, los quásares y las posibilidades de que no estemos solos en el universo. También habla de la imposibilidad de viajar más rápido que la luz y de la esperanza de encontrar los agujeros de gusano, que nos permitirían conocer otros mundos.

14 Milliarden Jahre in 2 Stunden und 24 Minuten - Kurz und knackig: Das Wichtigste über das Universum - für Leute, die wenig Zeit haben. Die junge Oxforder Astrophysikerin Becky Smethurst führt in zehn kurzen Kapiteln zügig durchs Weltall. Was existierte vor dem Big Bang, gibt es da draußen noch andere Lebewesen, was ist das Geheimnis Dunkler Materie und Schwarzer Löcher? Für alle, die große Fragen ans Universum haben, und diese gerne sowohl wissenschaftlich als auch humorvoll beantwortet hätten. Becky Smethursts Begeisterung für Astrophysik ist mitreißend.

Immanuel Kant (1724-1804) ist bis heute einer der bedeutendsten Philosophen. Neben seinen großen Kritiken verfasste Kant auch Schriften zu Religion, Geschichte und Naturwissenschaften. Bis heute ist die sogenannte Kant-Laplace-Theorie die anerkannte Erklärung der Entstehung unseres Planetensystems. In seiner kleinen, wenig bekannten Schrift "Etwas über den Einfluß des Mondes auf die Witterung" untersucht Kant Lichtenbergs Zitat "Der Mond sollte zwar nicht auf die Witterung Einfluß haben; er hat aber doch Einfluß.

Avi Loeb ist einer der renommiertesten Astronomen unserer Zeit. Und er ist sich sicher: Wir sind nicht allein im All. Denn Form und Eigenschaften des unbekannten Flugobjekts, das im Oktober 2017 durch unser inneres Sonnensystem schoss, ließen nur eine Erklärung zu: Oumuamua, wie man es nannte, war Alien-Technologie, von einer außerirdischen Zivilisation entwickelt und auf Erkundungsflug.

Nel novembre 2018 l'astrofisico Federico Nati parte per una missione in Antartide con un team internazionale. La missione è rischiosa e ambiziosa: spedire nella stratosfera un telescopio di tre tonnellate per studiare la nascita delle stelle e le origini del cosmo. Gli scienziati combattono contro le difficoltà del lavoro sperimentale, amplificate dalla ostilità dell'ambiente polare, per portare a compimento l'esperimento su cui hanno scommesso anni di lavoro e carriera.

"Oggi il ministro, con mia sorpresa, mi ha comunicato la revoca dell'incarico di presidente ASI. È il primo spoils system di ente di ricerca. Grazie alle migliaia di persone con cui ho condiviso quattro anni fantastici di spazio italiano." Con questo messaggio, il 6 novembre 2018, Roberto Battiston annuncia il suo allontanamento dall'Agenzia spaziale italiana. Un cambio improvviso, imposto dalla politica, diventa per l'autore l'occasione di raccontare per la prima volta dall'interno il mondo dello spazio italiano.

Questo libro è il resoconto di un viaggio cosmico dalla Terra alla Luna e oltre, tra i pianeti e i satelliti del Sistema Solare. A guidare la navicella è Piergiorgio Odifreddi, che ha arruolato come membri del suo equipaggio Plutarco, il grande storico e filosofo antico, Keplero, uno dei fondatori dell'astronomia moderna, e Huygens, il maggiore scienziato vissuto nel mezzo secolo che separò Keplero e Galileo da Newton.

Es ist eine Weltsensation: Am 10. April 2019 präsentiert Heino Falcke das erste Bild eines Schwarzen Lochs - ein Wendepunkt in der Astronomie. Nun erklärt er uns, wie es dazu kam, von den ersten Blicken der Menschen hoch zum Himmel bis zur modernen Astrophysik, der Erforschung der Schwarzen Löcher und den noch unenthüllten Geheimnissen des Universums - und was das mit ihm und uns Menschen generell zu tun hat.

Françoise Combes vient de recevoir la médaille d'or du CNRS. Cette astrophysicienne est spécialiste de la dynamique des galaxies et, non contente de les observer, elle réalise de spectaculaires simulations numériques de leur formation, de leur croissance, de leurs rencontres. Cela aide à comprendre l'origine de leurs formes, variées et souvent surprenantes. Le décodage des différentes étapes de leur évolution montre que les trous noirs supermassifs, qui occupent les centres de ces galaxies, y jouent un rôle majeur. Il est donc indispensable de mieux les comprendre.

A wry and compelling take on the who, how, and why of near-future colonies in space. From bone-whittling microgravity to eye-popping profits, the risks and rewards of space settlement have never been so close at hand.

From lunar logic to retrograde real talk, eclipses to asteroids, practicing astrologer Rachel Stuart-Haas breaks down the astrological phenomena that impact your day-to-day life in this giftable guide to the heavens and what they have in store.

Astrophysicist and best-selling author Mario Livio draws on his own scientific expertise to provide captivating insights into how Galileo reached his bold new conclusions about the cosmos and the laws of nature. A freethinker who followed the evidence wherever it led him, Galileo was one of the most significant figures behind the scientific revolution. He believed that every educated person should know science as well as literature, and insisted on reaching the widest audience possible, publishing his books in Italian rather than Latin.

Four more series of Brian Cox and Robin Ince’s multi award-winning science/comedy show - including the 100th episode and 'The Infinite Moonkey Cage', a special hour-long episode celebrating the 50th Anniversary of the Apollo moon landings. One of BBC Radio 4’s most popular programmes, The Infinite Monkey Cage sees Physicists Robin Ince and Brian Cox taking a witty, irreverent look at the world through Scientists’ eyes.

Beneath the Night is a history of humanity, told through our relationship with the night sky. From prehistoric cave art and Ancient Egyptian zodiacs to the modern era of satellites and space exploration, Stuart Clark explores a fascination shared across the world and throughout millennia. It is one that has shaped our scientific understanding; helped us navigate the terrestrial world; provided inspiration for our poets, artists and philosophers; and it has given us a place to project our hopes and fears. In the stars, we can see our past - and ultimately, our fate.

In recent years Greg - a.k.a. 'Space Gandalf' - has taken on cult status among audiences via his appearances alongside Professor Brian Cox in the hit TV series Stargazing Live. Greg's practical explanations of the complexities of space have also earned him respect from astronomers around the world. Is The Moon Upside Down? is an absorbing guided tour of the cosmos as seen through Greg's eyes.

In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons.

In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

In Search of a Theory of Everything takes listeners on an adventurous journey through space and time on a quest for a unified "theory of everything" by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics.

This compelling book describes how the Big Bang theory arose, how it has evolved, and why it is the best theory so far to explain the current state of the universe. In addition to understanding the birth of the cosmos, listeners will learn how the theory stands up to challenges and what it fails to explain. Karen Fox provides clear answers to some of the hardest questions including: Why was the Big Bang theory accepted to begin with? Will the Big Bang theory last into the next century or even the next decade? Is the theory at odds with new scientific findings?
