Titres dans Astronomie et science de l’espace

Certaines ne sont visibles qu'avec les plus grands télescopes. D'autres brillent si intensément qu'elles peuplent nos mythes depuis l'aube de l'humanité. Elles sont désignées par de mystérieuses références ou portent haut leur nom - Alcyone, Monocerotis, Ras Algethi, Thuban, Zeta Ophiuchi, etc. Les étoiles nous fascinent, mais les connaissons-nous vraiment ?

Does alien life exist? Is time travel possible? How did the universe begin, and how will it end? Is the future predetermined? These are just some of the fascinating questions posed in this book, which stretches across physics, the life sciences and cosmology. Each chapter considers a separate question and ends with either an answer or, if there is insufficient evidence, a ‘best guess’ answer.

Americans are fascinated by the undeniable mystique of the elite world of Navy fighter pilots. In Bogeys and Bandits, Robert Gandt takes listeners on a thrilling ride in the FA-18 Hornet, one of the fastest, sleekest, and deadliest aircraft in the world. Gandt lived and worked with several pilots learning to fly the Hornet: the identical twins from Middle America; the computer nerd with a penchant for speed; the grandson of a Tuskegee Airman, trying to live up to a proud legacy; and two women dealing with the post-Tailhook world of the Navy.

On October 4, 1957, a time of Cold War paranoia, the Soviet Union secretly launched the Earth's first artificial moon. No bigger than a basketball, the tiny satellite was powered by a car battery. Yet, for all its simplicity, Sputnik stunned the world.

NASA’s history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America’s space agency wasn’t created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. Breaking the Chains of Gravity tells the story of America’s nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military.

The human race is at a crossroads. In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of Star Trek, where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species - or the closed, dystopian, and ultimately self-destructive world of Soylent Green. If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars.

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

For centuries, people have speculated about the possibility of planets orbiting distant stars, but only since the 1990s has technology allowed astronomers to detect them. At this point, more than five thousand such exoplanets have been identified, with the pace of discovery accelerating after the launch of NASA’s Transiting Exoplanet Satellite Survey and the Webb Space Telescope. In The Little Book of Exoplanets, Princeton astrophysicist Joshua Winn offers a brief and engaging introduction to the search for exoplanets and the cutting-edge science behind recent findings.

Everyone gets need of Vashikaran Specialist during the course of life. As we know that there are various hurdles which may come to one's life and hence disturb the person. Vashikaran Specialist Everyone gets need of Vashikaran Specialist during the course of life. As we know that there are various hurdles which may come to one’s life and hence disturb the person. Even if a person is capable to tackle with them but the fact is this not all the individuals have ability to take right decision against the concerns of life and to apply them as well for their resolution. This is the reason ...

Qu’il vive en ville, à la campagne, en Europe, en Afrique, au xxie siècle ou il y a plus de 2 000 ans, l’être humain lève les yeux vers le ciel pour essayer de trouver des réponses à des questions existentielles. Notre histoire commune a engendré nos savoirs, et c'est cette épopée que je veux raconter ici. Cette odyssée est aussi la mienne, et j'en propose un récit personnel, intime.

"The Accelerating Universe is not only an informative book about modern cosmology. It is rich storytelling and, above all, a celebration of the human mind in its quest for beauty in all things." (Alan Lightman, author of Einstein's Dreams)

Is it science? Is it religion? What exactly is the Design Revolution? This book answers the toughest questions about Intelligent Design. As the Intelligent Design movement has gained momentum over recent years, questions have naturally arisen to challenge its provocative claims. With clarity and concision, William Dembski responds to the most vexing questions and objections raised by experts and non-experts.

The next frontier in space exploration is Mars, the Red Planet - and human habitation of Mars isn't much farther off. In October 2015, NASA declared Mars "an achievable goal"; that same season, Ridley Scott and Matt Damon's The Martian drew crowds into theaters, grossing over $200 million. Now the National Geographic Channel fast forwards years ahead with Mars, a six-part series documenting and dramatizing the next 25 years as humans land on and learn to live on Mars.

For decades, books, movies, television shows, and conspiracy theories have speculated about the existence of life on other planets. But how possible is it that we are alone in the universe? How likely is it we’ll find a habitable, Earth-like planet? How come we have not already seen signs of extraterrestrial life? Join astrophysicist Sarah Rugheimer to reveal what we know about detecting life on other planets.

In this companion volume to Merlin’s Tour of the Universe, we visit again with Merlin, a timeless space traveler from Planet Omniscia, who answers a collection of imaginative questions about the cosmos from curious stargazers. Whether waxing poetic about Earth and its environs, the Sun and its stellar siblings, the world of light, physical laws, or galaxies near and far, Merlin’s remarks are engaging, humorous, and clear as a starry night sky.

In this thrilling history, David Baker captures the longest possible time span—from the Big Bang to the present day—in an astonishingly concise retelling. His impressive timeline includes the "rise of complexity" in the cosmos and the creation of the first atoms; the origin of all galaxies, stars, and our solar system; and the evolution of life on Earth, from tiny single-celled organisms to human beings.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Dr. Philip C. Plait sets the record straight on many modern hoaxes and myths. Appalled that millions of Americans don't believe in the moon landing, or that an egg stands on its end only on the vernal equinox, Plait hilariously spills the truth and informs us of scientific inaccuracies in our everyday vernacular.

Instead of “what if the South won the Civil War?” cosmologists ask, “what if the constants that make up the fundamental building blocks of physics were different?” Physicists argue that any slight change to the laws of physics would mean a disruption in the evolution of the universe - and our existence. With the many factors that had to align for us to exist, it can seem like the laws of physics might seem finely tuned to make our existence possible. Instead of a supernatural or divine explanation, this book explores the possibility is that our universe isn’t the only one.
