The determination of stellar ages is crucial for the development of our understanding of the universe and for constraining theoretical models of galaxy formation and planetary system evolution. The ages of stars provide scientists with timescales to identify the relevant physical processes...

El siglo XX se recordará como el de la era espacial. Durante las cuatro últimas décadas, además de la inolvidable hazaña de la llegada del hombre a la Luna, se han conseguido otros importantes logros: la exploración minuciosa de Marte y Venus, la visita a los planetas gigante Júpiter...

Our solar system is a dynamic arena where asteroids careen off course and solar winds hurl charged particles across billions of miles of space. Yet we seldom consider how these events, so immense in scale, influence our fragile blue planet: Earth. In Ripples on the Cosmic Ocean, Dagomar Degroot...

In 1965, two engineers in New Jersey tried to blame pigeons for a noise that would not go away. The noise turned out to be the oldest light in the universe, still arriving from every direction at once, cooling by one ten-billionth of a degree with every minute that passes. That light has been called the afterglow of the Big Bang — a phrase that is, strictly speaking, wrong. The cosmic background radiation is not the universe being born. It is the universe becoming transparent, roughly three hundred eighty thousand years after an event that had already quietly set the stage.

A Russian dissident, a Jesuit priest, and an American mule skinner are but a few of the bold visionaries who crafted the scientific story of cosmic origins. The collective insights of these and numerous creative thinkers advanced human understanding from mythology to mathematics, yielding falsifiable alternatives to ancient folklore and campfire tales. Listening to the Big Bang tells the dramatic human story—filled with colorful characters, unsung catalysts, and glorified heroes—which made the Big Bang the leading cosmological theory.

Los últimos descubrimientos sobre el cosmos explicados con sencillezy con una sola fórmula: E= mc2. Es raro el día en el que no aparezca una noticia en los medios de comunicación sobre algún hallazgo de la astrofísica. Exoplanetas, púlsares, agujeros negros, cuásares, Big Bang, universo...

Rédigés par Becky Smethurst, astrophysicienne à l'université d'Oxford, les dix petits textes qui composent ce livre vous guideront à travers les galaxies et les trous noirs, et vous raconteront pourquoi la matière noire est l'une des énigmes les plus fascinantes du cosmos. Vous apprendrez...

'One of the most accomplished and important science writers of our time' ED YONG 'Chanda Prescod-Weinstein brings light to our universe' ROBIN INCE In The Edge of Space-Time, Chanda Prescod-Weinstein takes readers to the boundaries of the universe, inviting us to spend time at the edge of what...

A bold and all-embracing exploration of the nature and progress of knowledge from one of today's great thinkers. Throughout history, mankind has struggled to understand life's mysteries, from the mundane to the seemingly miraculous. In this important new book, David Deutsch, an award-winning pioneer in the field of quantum computation, argues that explanations have a fundamental place in the universe.

Malcolm Gladwell, author of New York Times best sellers including Talking to Strangers and host of the podcast Revisionist History, uses original interviews, archival footage, and his trademark insight to weave together the stories of a Dutch genius and his homemade computer, a band of brothers in Central Alabama, a British psychopath, and pyromaniacal chemists at Harvard. As listeners hear these stories unfurl, Gladwell examines one of the greatest moral challenges in modern American history.

Look up at the night sky. Every star, every galaxy, every wisp of nebula appears perfectly, eternally still. The constellations that Hipparchus cataloged over two thousand years ago remain recognizable tonight. The Universe seems frozen. It is not. Behind that apparent stillness rages a cosmos of extraordinary violence: galaxies colliding over hundreds of millions of years, stars being born and dying in thermonuclear cataclysms, space itself expanding and carrying everything apart. The Universe is not frozen. We are merely too brief to see it move.

¿Cuáles son los mayores retos con los que se presenta el planeta, cuáles las mayores amenazas, dónde buscar la solución a los descomunales problemas con los que se enfrenta nuestra generación y las futuras? El origen y evolución del universo, la naturaleza del tiempo, la estructura de la materia, el infinito,las estrellas fugitivas, las ondas gravitacionales…Estos son algunos de los grandes temas que Rafael Bachiller aborda en este libro tanto desde un punto de vista científico como desde una perspectiva filosófica y humanista.

This new and long-awaited sequel to Carl Sagan's international best seller continues the electrifying journey through space and time, linking worlds within and worlds billions of miles away and envisioning a future of science tempered with wisdom. Based on National Geographic's internationally-renowned television series, this groundbreaking and visually stunning book explores how science and civilization grew up together.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

Everything we now know about the universe - from the behavior of quarks to the birth of galaxies - has come from people who've been willing to ponder the unanswerable. And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of grappling with some of the universe's most vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered and explored by today's scientists?

La ciencia ficción nos permite visitar lugares que sólo podemos soñar ver: otros mundos, estrellas lejanas, galaxias enteramente nuevas. No todos los relatos se ocupan de la ciencia real que hay detrás de los viajes espaciales y otras empresas futuristas, pero la ficción puede ofrecer una perspectiva asombrosa de hasta dónde podrían llegar nuestras capacidades y de lo que soñamos con hacer.

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.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

What forces molded the universe? Are those forces still at work, removing, changing, or adding heavenly bodies even as we gaze upward? Will humanity, and Earth itself, one day be gone? Are we alone? In an era when science journalism is perhaps more thorough and ambitious than ever before, fascinating explorations of questions like these seem available to us almost every day - provided we have a working understanding of the scientific theories on which they're based.
