Could Einstein have possibly anticipated directly testing the most captivating prediction of general relativity, that there exist isolated pockets of spacetime shielded completely from our own? Now, almost a century after that theory emerged, one of the world's leading astrophysicists presents a wealth of recent evidence that just such an entity, with a mass of about three million suns, is indeed lurking at the center of our galaxy, the Milky Way--in the form of a supermassive ''black hole''! With this superbly illustrated, elegantly written, nontechnical account of the most enigmatic astronomical object yet observed, Fulvio Melia captures all the excitement of the growing realization that we are on the verge of actually seeing this exotic object within the next few years. Melia traces our intellectual pilgrimage to the ''brooding behemoth'' at the heart of the Milky Way. He describes the dizzying technological advances that have recently brought us to the point of seeing through all the cosmic dust to a dark spot in a clouded cluster of stars in the constellation Sagittarius. Carefully assembling the compelling circumstantial evidence for its black hole status, he shows that it is primed to reveal itself as a glorious panorama of activity within this decade--through revolutionary images of its ''event horizon'' against the bright backdrop of nearby, radiating gas. Uniquely, this book brings together a specific and fascinating astronomical subject--black holes--with a top researcher to provide both amateur and armchair astronomers, but also professional scientists seeking a concise overview of the topic, a real sense of the palpable thrill in the scientific community when an important discovery is imminent.

Reviewing the fundamental instrumental techniques and current observational results, this book unveils the mysteries of the physical processes in the central parsec of our Milky Way: the super-massive black hole embedded in a central stellar cluster as well as the gas and dust in the circumnuclear region. The observations described cover the entire electromagnetic spectrum from decimeter radio-waves to high energy X-ray and ?-rays, and a comprehensive summary of up-to-date astrophysical interpretations is given. The emphasis is put on observational techniques, image processing aspects, and a detailed presentation of the most cutting-edge work carried out in the near-infrared wavelength regime. These recent results include both the first orbits of stars around the central black hole and the multiwavelength variability of the central source.

Today, we recognize that we live on a planet circling the sun, that our sun is just one of billions of stars in the galaxy we call the Milky Way, and that our galaxy is but one of billions born out of the Big Bang. Yet as recently as the early twentieth century, the general public and even astronomers had vague and confused notions about what lay beyond the visible stars. Can we see to the edge of the universe? Do we live in a system that would look, from a distance, like a spiral nebula? This fully updated second edition of Minding the Heavens: The Story of Our Discovery of the Milky Way explores how we learned that we live in a galaxy, in a universe of composed of galaxies and unseen, mysterious dark matter. The story unfolds through short biographies of seven astronomers: Thomas Wright, William Herschel, and Wilhelm Struve of the 18th and 19th centuries; the transitional figure of William Huggins; and Jacobus Kapteyn, Harlow Shapley, and Edwin Hubble of the modern, big-telescope era. Each contributed key insights to our present understanding of where we live in the cosmos, and each was directly inspired by the work of his predecessors to decipher "the construction of the heavens." Along the way the narrative weaves in the contributions of those in supportive roles, including Caroline Herschel—William’s sister, and the first woman paid to do astronomy—and Martha Shapley, a mathematician in her own right who carried out calculations for her spouse. Through this historical perspective readers will gain a new appreciation of our magnificent Milky Way galaxy and of the beauties of the night sky, from ghostly nebulae to sparkling star clusters. Features: Fully updated throughout to reflect the latest in our understanding of the Milky Way, from our central supermassive black hole to the prospect of future mergers with other galaxies in our Local Group. Explains the significance of current research, including from the Gaia mission mapping our galaxy in unprecedented detail Unique and broadly appealing approach. A biographical framework and ample illustrations lead the reader by easy, enjoyable steps to a well-rounded understanding of the history of astronomy. Praise for the first edition— "A terrific blend of the science and the history." - Marth Haynes, Goldwin Smith Professor of Astronomy, Cornell University "The book is a treat... Highly recommended for public and academic libraries." -Peter Hepburn (now Head Librarian, College of the Canyons, Santa Clarita, California)

Black holes entered the world of science fiction and films in the 1960s, and their popularity in our culture remains today. The buzz surrounding black holes was and is due, in large part, to their speculative nature. It is still difficult for the general public to determine fact versus fiction as it pertains to this terrifying idea: something big enough to swallow anything and everything in close proximity, with a gravitational force so strong that nothing, including light, can escape. In the fall of 2015, scientists at the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the first sounds from black holes, brought to earth by the gravitational waves that emitted from the merging of two black holes 1.4 billion light years away in space. This confirmed the existence of gravitational waves, which Albert Einstein predicted in 1916. In the spring of 2017, physicists and astronomers who were working on the Event Horizon Telescope (EHT) project captured the first image of a black hole. This was the supermassive black hole hosted by the galaxy M87 in the constellation Virgo, 53 million light years away, and the image shows the shadow the black hole casts upon the bright light surrounding it. In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Here it is, in a nutshell: the history of one genius’s most crucial work – discoveries that were to change the face of modern physics. In the early 1900s, Albert Einstein formulated two theories that would forever change the landscape of physics: the Special Theory of Relativity and the General Theory of Relativity. Respected American academic Professor Tai Chow tells us the story of these discoveries. He details the basic ideas of Einstein, including his law of gravitation. Deftly employing his inimitable writing style, he goes on to explain the physics behind black holes, weaving into his account an explanation of the structure of the universe and the science of cosmology.

Portraying themselves as challenging blind religious dogma with evidence-led skepticism, the neo-atheist movement claims that the New Testament contains unreliable tales about a mythical figure who, far from being the resurrected Lord of life, may not even have lived. This comprehensive critique documents the falsehood of these neo-atheist claims, correcting their historical and philosophical mistakes to show how we can get at the truth about the historical Jesus.

The astonishing science of black holes and their role in understanding the history and future of our universe. Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Every massive star leaves behind a black hole when it dies, and every galaxy harbors a supermassive black hole at its center. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Which came first, the galaxy or its central black hole? What happens if you travel into one—instant death or something weirder? And, perhaps most important, how can we ever know anything for sure about black holes when they destroy information by their very nature? In Einstein’s Monsters, distinguished astronomer Chris Impey takes readers on an exploration of these and other questions at the cutting edge of astrophysics, as well as the history of black holes’ role in theoretical physics—from confirming Einstein’s equations for general relativity to testing string theory. He blends this history with a poignant account of the phenomena scientists have witnessed while observing black holes: stars swarming like bees around the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding, releasing ripples in space-time. Clear, compelling, and profound, Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones—from the tiniest particles to the nature of space-time itself—black holes might be the key to a deeper understanding of the cosmos.

A scientist’s inspiring vision of our return to the Moon as humanity’s next thrilling step in space exploration Just over half a century since Neil Armstrong first stepped foot on the lunar surface, a new space race to the Moon is well underway and rapidly gaining momentum. Laying out a vision for the next fifty years, Back to the Moon is astrophysicist Joseph Silk’s persuasive and impassioned case for putting scientific discovery at the forefront of lunar exploration. The Moon offers opportunities beyond our wildest imaginings, and plans to return are rapidly gaining momentum around the world. NASA aims to build a habitable orbiting space station to coordinate lunar development and exploration, while European and Chinese space agencies are planning lunar villages and the mining of precious resources dwindling here on Earth. Powerful international and commercial interests are driving the race to revisit the Moon, but lunar infrastructures could also open breathtaking vistas onto the cosmos. Silk describes how the colonization of the Moon could usher in a thrilling new age of scientific exploration, and lays out what the next fifty years of lunar science might look like. With lunar telescopes of unprecedented size situated in permanently dark polar craters and on the far side of the Moon, we could finally be poised to answer some of the most profound questions confronting humankind, including whether we are alone in the Universe and what our cosmic origins are. Addressing both the daunting challenges and the immense promise of lunar exploration and exploitation, Back to the Moon reveals how prioritizing science, and in particular lunar astronomy, will enable us to address the deepest cosmic mysteries.

According to the authors of this book, who explore evolutionary theory from a clear Christian perspective, the common view of conflict between evolutionary theory and Christian faith is mistaken. Written by contributors representing the natural sciences, philosophy, theology, and the history of science, this thought-provoking work is informed by both solid scientific knowledge and keen theological insight. The three sections of the book address (1) relevant biblical, historical, and scientific background, (2) the scientific evidence for an evolving creation, and (3) theological issues commonly raised in connection with evolution, including the nature of God's creative activity, the meaning of the miraculous, and the uniqueness of humankind. Woven through the volume are short meditations designed to direct readers toward worshiping the God of providence. Contributors: Laurie J. Braaten Warren S.

What happens when the Long Count ends? That's what a team of scientists situated near Izapa, Mexico, sets out to determine in the years leading up to December 21, 2012 - the end date of the Long Count, the ancient Mayan calendar which some believe predicts the end of the world. When infighting threatens to break up the team before the solution is found, one unscrupulous member advances a theory that puts world armies on alert, brings religious organizations to a tipping point and global society to a panic. As thousands flock to Izapa on the end date to wait for the world to end, the team realizes too late that the danger they thought would come from outside the human race actually comes from within.
