09.07 am. 12 de abril de 1961. Un cohete de alto secreto en la URSS. Un joven ruso se sienta en una minúscula cápsula encima del misil balístico intercontinental más potente de la Unión Soviética -diseñado originalmente para transportar una cabeza nuclear- y despega hacia el cielo. Se llama Yuri Gagarin. Y está a punto de hacer historia.

How big is the universe? In the early twentieth century, scientists took sides. One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.

Written by the Officer Commanding and former Red 1 Team Leader, Wing Commander David Montenegro, and full of never-before-shared tales from pilots past and present, this thrilling history is both a faithful record and a fascinating account of not only what it takes, but what it means, to be a Red Arrow.

Enrique Joven, astrofísico, tras la experiencia que da el observar durante muchos años las estrellas, ha escrito una historia de los astrónomos. En el contexto en el que vivieron y observaron el cielo con pasión para intentar comprenderlo, rescatando sus increíbles hallazgos y sorprendentes vicisitudes.

I don’t think many people know that the moon is not actually a perfect sphere; it is in fact shaped slightly like a lemon with bulges on both sides. Or that a day on Mercury lasts longer than a year. These are just a few of the many interesting facts that you will discover about space in this audiobook. If you’re like me, anything space related will fascinate you; there is just something exciting about the big wide world out there beyond Earth, the many unknowns, and the interesting facts that are being discovered on a daily basis.

A Degree in a Book: Cosmology is the perfect introduction to cosmology, astronomy, and astrophysics, written by one of NASA's leading astronomers and educators. Filled with helpful diagrams, suggestions for further reading and easily digestible history sections, this audiobook makes it easier than ever to understand the workings of the Universe. Featuring the most important ideas in the field, including the theory of relativity, the standard model, loop quantum gravity, and supersymmetry, it covers the whole breadth of cosmology.

Mind Openers 2.0 is the second installment in a two-part set. It takes a fresh look at relativity, cosmology, and quantum theory by imagining a “sandbox universe”, in which space and time are treated as tangible and visualizable phenomena. In addition to providing an intuitive feel for the physics, the model makes a number of acutely unexpected predictions. The author is a geophysicist (MSc, fellow of geoscientists, Canada) and educator, who specializes in translating scientific material for the non-expert.

Mit diesem Hörbuch begeben Sie sich auf eine Reise vom Beginn des Universums in die ferne Zukunft: Was ist Zeit? Kann man den Urknall sehen? Wie funktioniert Inflation? Wie entstehen Sterne? Wie untersucht man Exoplaneten? Wie sieht die Zukunft des Universums aus? Kann die Zeit enden? Fünfzehn allgemeinverständliche Beiträge aus Spektrum der Wissenschaft und Sterne und Weltraum bieten dem Leser einen vielfältigen Blick auf unser Universum: der erste Teil der Beiträge beschäftigt sich mit dem frühen Universum, mit Zeit, Urknall, Inflation und Dunkler Materie.

Galileo’s Dialogue Concerning the Two Chief World Systems compares the Copernican or Heliocentric system with the Ptolemaic or Peripatetic, system of the cosmos. Published in Florence in 1632, it resulted in him being tried before the Inquisition. Using the dialogue form, Galileo masterfully shows the truth of the Copernican system that the Earth revolves around the Sun. The Dialogue is one of the most important treatises ever written. A work of supreme clarity and accessibility, it remains as accessible now as when it was published.

Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this mass energy “dark matter,” and the ancients called it life force, prana, or chi.

During the formative years of Egyptian civilization, each Cosmogony was present. Students from many regions and segments of society attended the Houses of Life, and royals regularly donated endowments for the temple's maintenance and activities. These circumstances suggest a theological harmony, suggesting that a group of religious centers must have been cohesive despite their distinctive teachings and practices. Regardless of time or place in popularity, each creation myth was integral to the Egyptians' worldview.

No direct explanation is given for the origin and nature of the luminous bodies, the sun, the planets, and the stars. Because the Sumerians regarded the moon-god, who went by the names Sin and Nanna, as the son of the air-god Enlil, it does not seem unreasonable to suggest that they saw the moon as a bright, air-like body fashioned from the atmosphere. As the sun-god Utu and the Venus goddess Inanna are always referred to as children of the moon-god, these luminous bodies were probably imagined as having come from the moon after the latter had been formed from the atmosphere.

The Apollo 12 moon mission was the second manned mission to the lunar surface, but what made it unique was that all three astronauts on this particular mission were already good friends and Navy buddies well before they became astronauts. This audiobook provides the previously untold story of this mission by those who were actually there in that era, and contains the uncensored, unedited, unfiltered, and previously unreleased interviews with all three of these Apollo 12 astronauts.

The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces and how such signatures might be detected elsewhere in the solar system or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions.

At the two four-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015, they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected, and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a powerful new path to understand the workings of the universe.

Decía Carl Sagan que para hacer una tarta de manzana primero hay que crear el universo. Harry Cliff, prestigioso físico de la Universidad de Cambridge, emprende la búsqueda de la receta perfecta recogiendo los ingredientes a través del cosmos, en los núcleos de estrellas moribundas, y retrocediendo en el tiempo hasta la fracción de segundo inmediatamente posterior a la que todo se creó, para entender, entre otras muchas cosas, de dónde proviene la materia.

Every minute, several huge “snowballs” break up as they approach the Earth and deposit a large cloud of water vapor in Earth’s upper atmosphere. That’s the startling finding that world-renowned physicist Louis A. Frank came to after studying the images from the Dynamics Explorer 1 spacecraft. His conclusion, based on data acquired at the limits of detection, created a storm of controversy among scientists. This is the story that was told in The Big Splash, published in 1990. But, the story does not end there.

Sometimes our understanding of our universe is given a huge boost by one insightful thinker. Such a boost came in the first half of the 20th century, when an obscure Belgian priest put his mind to deciphering the nature of the cosmos. The Day Without Yesterday covers the modern history of an evolving universe, and how Georges Lemaître convinced a generation of thinkers to embrace the notion of cosmic expansion and the theory that this expansion could be traced backward to the cosmic origins, a starting point for space and time that Lemaître called "the day without yesterday".

Brad Steiger, the world-renowned authority on unexplained phenomena, presents a collection of UFO encounters and abductions. His provocative theories provide answers to the most puzzling questions: Why are they here? What do they want? And how will they change the fate of the human race?
