As our closest stellar companion and composed of two Sun-like stars and a third small dwarf star, Alpha Centauri is an ideal testing ground of astrophysical models and has played a central role in the history and development of modern astronomy—from the first guesses at stellar distances to understanding how our own star, the Sun, might have evolved. It is also the host of the nearest known exoplanet, an ultra-hot, Earth-like planet recently discovered. Just 4.4 light years away Alpha Centauri is also the most obvious target for humanity’s first directed interstellar space probe. Such a mission could reveal the small-scale structure of a new planetary system and also represent the first step in what must surely be humanity’s greatest future adventure—exploration of the Milky Way Galaxy itself. For all of its closeness, α Centauri continues to tantalize astronomers with many unresolved mysteries, such as how did it form, how many planets does it contain and where are they, and how might we view its extensive panorama directly? In this book we move from the study of individual stars to the study of our Solar System and our nearby galactic neighborhood. On the way we will review the rapidly developing fields of exoplanet formation and detection.

I wrote this book because I wanted to learn more about interstel lar flight. Not the Star Trek notion of tearing around the Galaxy in a huge spaceship-that was obviously beyond existing tech nology-but a more realistic mission. In 1989 I had videotaped Voyager 2's encounter with Neptune and watched the drama of robotic exploration over and over again. I started to wonder whether we could do something similar with Alpha Centauri, the nearest star to the Sun. Everyone seemed to agree that manned flight to the stars was out of the question, if not permanently then for the indefinitely foreseeable future. But surely we could do something with robotics. And if we could figure out a theoretical way to do it, how far were we from the actual technology that would make it happen? In other words, what was the state of our interstellar technology today, those concepts and systems that might translate into a Voyager to the stars? Finding answers meant talking to people inside and outside of NASA. I was surprised to learn that there is a large literature of interstellar flight. Nobody knows for sure how to propel a space craft fast enough to make the interstellar crossing within a time scale that would fit the conventional idea of a mission, but there are candidate systems that are under active investigation. Some of this effort begins with small systems that we'll use near the Earth and later hope to extend to deep space missions.

“Stephen Baxter has been heralded, with some merit, as Arthur C. Clarke’s literary heir, and Proxima certainly reinforces this accolade in spades.”—Concatenation Mankind’s future in this galaxy could be all but infinite. There are hundreds of billions of red dwarf stars, lasting trillions of years—and their planets can be habitable for humans. Such is the world of Proxima Centauri. And its promise could mean the never-ending existence of humanity. But first it must be colonized, and no one wants to be a settler. There is no glamor that accompanies it, nor is there the ease of becoming a citizen of an already-tamed world. There is only hardship...loneliness...emptiness, even as war brews in the solar system. But that’s where Yuri comes in. Because sometimes exploration isn’t voluntary. It must be coerced.

Radiating fire and ice, comets as a phenomenon seem part science, part myth. Two thousand years ago when a comet shot across the night sky, it convinced the Romans that Julius Caesar was a god. In 1066, Halley’s Comet was interpreted as a foreshadowing of the death of Harold the Second in the Battle of Hastings. Even today the arrival of a comet often feels auspicious, confirming our hopes, fears, and sense of wonder in the universe. In Comets, P. Andrew Karam takes the reader on a far-ranging exploration of these most beautiful and dramatic objects in the skies, revealing how comets and humanity have been interwoven throughout history. He delves into the science of comets and how it has changed over time; the way comets have been depicted in art, religion, literature, and popular culture; and how comets have appeared in the heavens through the centuries. Comprehensive in scope and beautifully illustrated throughout, the book will appeal not only to the budding astronomer, but to anyone with an appreciation for these compelling and remarkable celestial bodies.

Download Voyage to Alpha Centauri Book in PDF, ePub and Kindle
Set eighty years in the future, this novel by the best-selling author Michael O'Brien is about an expedition sent from the planet Earth to Alpha Centauri, the star closest to our solar system. The Kosmos, a great ship that the central character Neil de Hoyos describes as a "flying city", is immense in size and capable of more than half light-speed. Hoyos is a Nobel Prize winning physicist who has played a major role in designing the ship. Hoyos has signed on as a passenger because he desires to escape the seemingly benign totalitarian government that controls everything on his home planet. He is a skeptical and quirky misanthropic humanist with old tragedies, loves, and hatreds that are secreted in his memory. The surprises that await him on the voyage-and its destination-will shatter all of his assumptions and point him to a true new horizon. Science fiction and fantasy literature are genres that have become dominant forces in contemporary worldwide culture. Our fascination with the near-angelic powers of new technology, its benefits and dangers, its potential for obsession and catastrophe, raises vital questions that this work explores about human nature and the cosmos, about man's image of himself and where he is going-and why he seeks to go there.
