"Vous êtes à quelques milliers de kilomètres au-dessus de la surface du Soleil. Sa puissance est à couper le souffle. D'énormes boules magnétiques gonflent et se percent, éjectant vers l'espace des milliards de tonnes de matière brûlante qui transpercent votre corps éthéré. Le spectacle est extraordinaire et vous vous demandez soudain, avec une légère jalousie, ce qui rend le Soleil si spécial par rapport à la Terre."

Alex Vilenkin resume en este audiolibro, de una forma amena y accesible, la historia de las investigaciones de los últimos cincuenta años en torno al origen y la evolución del universo. Vilenkin hace hincapié en dos teorías en las que es especialmente innovador: la inflación eterna del cosmos y la existencia de múltiples universos... en alguno de los cuales tal vez ahora nos hallemos replicados, sosteniendo este mismo libro en nuestras manos.

Pourquoi y a-t-il des atomes, des planètes et des humains plutôt que rien ? Comment pouvons-nous aimer, créer, croire, agir, penser... alors que notre cerveau est le fruit des lois déterministes de la physique ? La conscience est-elle apparue par la seule grâce du hasard ? Et si les étoiles sont appelées à terme à se consumer, les galaxies à se disperser et les trous noirs à s'évaporer comme l'a prédit Stephen Hawking, quel sens donner à notre existence ?

Space is filled with wondrous and mind-boggling objects. New discoveries are made every year. This book has 199 trivia questions to test your memory. But you don’t have to worry if you get stumped. The answer is revealed and includes 557 out-of-this-world facts. This book covers a broad spectrum of thought-provoking questions, such as:

The sky has always held significance for humanity, in both cultural and scientific terms. And yet we persistently pollute it with sometimes unnecessary light in our obsessive desire to chase away the darkness. This effectively switches off the stars, hampering our ability to enjoy one of the most inspiring sights nature has to offer to humankind. In addition, too much light is hazardous to both our health and that of the fauna and flora of this planet.

What’s so funny about space and science? Our season finale features the incomparable comedian Joan Rivers. In this episode, she provides color commentary for a Red Carpet parade of previous show topics, including space tourism, the anniversary of Apollo 11, and the search for alien life (both in space and in Hollywood).

Richard Branson has formed Virgin Galactic and is now taking reservations aboard the maiden voyage of SpaceShipOne. Would you spend the estimated $200,000 for a 45-minute trip into space? Neil and Lynne also discuss the mechanics of sex in space.

What price do we put on knowledge? How does it profit a man if he learns about the universe, but goes to bed hungry? When the economy takes a downturn, should we still go up into space? NASA missions aren’t cheap - sending astronauts into low Earth orbit or to the Moon, sending robotic spacecraft to explore the planets, and launching telescopes into space can cost millions or even billions of dollars. Lou Friedman, director of the Planetary Society, argues that even when the dollar is dear, the quest to explore our universe is priceless.

Starry, starry nights, stormy and sun-filled days. Long summer days of picnics and ballgames are played out under a vast and gorgeous canvas of astronomical and meteorological curiosities. From the stories of the stars told by the ancients, to a recent mammatus cloud over CitiField in New York, learn about the phenomena in the summer skies that keep us looking up.

"That’s one small step for man, one giant leap for mankind." Neil Armstrong spoke these words after placing his foot down onto lunar soil, and throughout the course of the Apollo program, 11 other astronauts also walked on the Moon. In this show, Neil Armstrong, Buzz Aldrin, and many others share their memories of Apollo, and say what they think should be NASA’s next step in space.

This year marks the 400th anniversary of Galileo’s use of the first telescope. On this week’s show, we reflect on how telescopes have changed our perception of our place in the universe, how small we are in size, space, and time. Our guests include Dava Sobel, author of The Planets, Vatican Astronomer Father Chris Corbally, and astronaut Paul Richards.

Existe-t-il des planètes comparables à la Terre ? Hébergent-elles la vie ? La pluralité des mondes fascine les savants depuis des millénaires, de Démocrite jusqu'à Carl Sagan, en passant par Giordano Bruno et Camille Flammarion. Aujourd'hui, pour la première fois dans l'histoire de notre espèce, nous possédons la science et la technologie requises pour éclairer cette question, notamment grâce à la découverte de milliers d'exoplanètes et d'une profusion de "super-Terres".

Wir wissen, dass das Universum vor vielen Milliarden Jahren in einem gewaltigen Feuerball entstand - dem Urknall. Aber wie wird die Geschichte unseres Universums enden? Wird es in unvorstellbarer Hitze verglühen - oder in eisiger Starre vergehen? Wird es zu einem Klumpen unendlicher Dichte kollabieren, und wird das Ende wirklich das Ende sein - oder entsteht das Universum danach von Neuem? Die renommierte Astrophysikerin Katie Mack nimmt uns mit auf eine faszinierende Reise zu den Grenzen von Raum und Zeit und zeigt auf unterhaltsame Weise, was die Wissenschaft über das Ende des Kosmos weiß.

En 1916, Einstein predijo la existencia de ondas gravitacionales, su máxima prioridad después de proponer su teoría del espacio-tiempo curvo. Un siglo después, estamos grabando los primeros sonidos del espacio, evidencia de la existencia de las ondas causadas por la colisión de dos agujeros negros. Es la banda sonora que acompaña a la película muda de la astronomía. Janna Levin relata la ambición experimental que comenzó como un divertido experimento mental y se convirtió en objeto de obsesión para los arquitectos originales de la idea: Rai Weiss, Kip Thorne y Ron Drever.

Human exploration of Mars is the most ambitious and exciting scientific goal of the 21st century, and few people on earth know as much about this fascinating planet as Dr Larry Crumpler. As one of the long-term planning leads for the Mars Exploration Rover Project, he helped control the daily communications between NASA and the rovers roaming the planet to gather scientific data. In this magnificent compendium, Dr. Crumpler recounts the history of the red planet, from the earliest days when ancient astronomers turned their eyes to the heavens to the breakthrough discoveries.

Space is now big business. Technology originally developed for the space program sometimes ends up in products for use on Earth, often in surprising ways. The 40,000 certified “Space Products” range from mattresses to medical devices, and have turned space into a multi-billion-dollar industry. Inspired by our excursions into the Final Frontier, entrepreneurs and inventors are turning stardust into gold.

The United States Space Force has a noble mission - to protect America, to support our allies, and to support our nation's interest as we, along with other nations, move out into the little patch of the universe that is our home system. The desire to establish a US Space Force has been around for decades, in both science fiction and in the minds of people who attempt to seriously consider what our nation needs in order to deter future wars (and if necessary, to fight and win them).

Attempts by scientists and artists to reveal deep truths about the universe may take different forms, but they often end up agreeing with the poet John Keats that “truth is beauty”. Geometry, physics, and the other sciences describe the world we live in, and artists often play with these properties in their own imaginative investigations. From the drawings of Leonardo Da Vinci to high tech computer graphics, Neil and Lynne paint a picture of how science has inspired art through the ages.
