Einstein’s Shadow follows a team of elite scientists on their historic mission to take the first picture of a black hole, putting Einstein’s theory of relativity to its ultimate test and helping to answer our deepest questions about space, time, the origins of the universe, and the nature of reality Photographing a black hole sounds impossible, a contradiction in terms. But Shep Doeleman and a global coalition of scientists are on the cusp of doing just that. With exclusive access to the team, journalist Seth Fletcher spent five years following Shep and an extraordinary cast of characters as they assembled the Event Horizon Telescope, a worldwide network of radio telescopes created to study black holes. He witnessed the team’s struggles, setbacks, and breakthroughs, and, along the way, Fletcher explored the latest thinking on the most profound questions about black holes: Do they represent a limit to our ability to understand reality? Or will they reveal the clues that lead to the long-sought theory of everything? Fletcher transforms astrophysics into something exciting, accessible, and immediate, taking us on an incredible adventure to better understand the complexity of our galaxy, the boundaries of human perception and knowledge, and how the messy endeavor of science really works. Weaving a compelling narrative account of human ingenuity with excursions into cutting-edge science, Einstein’s Shadow is a tale of great minds on a mission to change the way we understand our universe—and our place in it.

"Black holes are one of the extraordinary phenomena in the universe whose existence was surmised not by observations, but by theory. The black hole is a prediction of Einstein's 1915-1916 gravitational theory, general relativity, which replaced Sir Isaac Newton's gravity theory, published in his famous treatise Principia in 1687. In 1784, Reverend John Michell, a fellow of Queens' College and Professor of Geology at Cambridge University, had already envisioned what we now call black holes. He asked what would happen if a star's gravity were so strong that its escape velocity - the speed at which a rocket, for example, would have to travel to leave the star - exceeded the speed of light? Michell realized that any light emanating from the star would have to fall back to its surface. He speculated that the escape velocity would exceed the speed of light for a very massive star, making the star invisible to an observer"--

Chasing Hubble's Shadows is an account of the continuing efforts of astronomers to probe the outermost limits of the observable universe. The book derives its title from something the great American astronomer Edwin Hubble once wrote: "Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial." The quest for Hubble's "shadows"—those unimaginably distant, wispy traces of stars and galaxies that formed within the first few hundred million years after the Big Bang—takes us back, in effect, to the beginning of time as we are able to perceive it, when the first discrete stellar objects appeared out of what has lately come to be known as the "cosmic dark age." The information that is being gleaned from these dim sources—chiefly with the aid of Hubble's namesake, the Hubble Space Telescope—promises to yield clues to many cosmic puzzles, including the nature of the mysterious "dark energy" that is now believed to pervade all of space.

Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for the naked eye, through binoculars and the largest backyard telescopes.

"Half-hours with the Telescope: Being a Popular Guide to the Use of the Telescope as a Means of Amusement and Instruction" by Richard A. Proctor has a lot of detail about telescopes such as the lens and focal length which increases an amateur stargazer's understanding to make his own telescope. While this book was written well before modern telescope models were on the market, it's still an essential resource as all versions use the same basic construction and require the same understanding.

A meticulously observed and macabre tale of hell on earth from the revolutionary German author of the famous play Marat/Sade Peter Weiss’s first prose work, The Shadow of the Coachman’s Body, was unanimously praised as an original and perfect work of art by critics when it appeared in 1960. Here, in poet Rosmarie Waldrop’s stunning translation, Weiss arranges a dark, vividly alive comedy of inert objects in a dismal boarding house—stones, buttons, hooks, needles, chairs, newspapers in an outhouse, clinking tin cups, celestial orbs, sewing machines, an overwound windup music box—which have oblique characters’ shadows as their supporting cast. Described by Weiss as a “micro-novel,” The Shadow of the Coachman’s Body can be obscene, trivial and brutal, and yet it is also peculiarly intimate and offers endless possibilities—like a telescope and kaleidoscope rolled into one.

The telescope is literally the world's most far-reaching invention. It can unlock nature's secrets in the remotest corners of the universe. It is a time machine, allowing us to look billions of years into the past for answers to some of our most profound questions. In its 400-year history, the telescope has progressed from a crudely fashioned tube holding a couple of spectacle lenses to colossal structures housed in space-age cathedrals. The history of the telescope is a rich story of ingenuity and perseverance involving some of the most colourful figures of the scientific world. It begins in ancient times, gathers momentum through the Renaissance, with the first recorded telescope bursting onto the scene in the middle of a diplomatic crisis in seventeenth century Holland, and takes us to the limits of space with the cutting-edge telescopes of today. Written by Fred Watson, one of Australia's best-loved astronomers, Stargazer brings the story of the telescope to a general readership for the first time.

Günther Buttman’s The Shadow of the Telescope was the first full-length biography of the nineteenth-century astronomer, Sir John Herschel. First published in German, this intriguing text chronicles the life and works of the third of the Herschel astronomers, the son of William and the nephew of Caroline. John was extremely intelligent, graduating as Senior Wrangler in the notoriously difficult Mathematical Tripos at Cambridge University. While less famous than his father and aunt, he nevertheless went on to make important discoveries in the field of astronomy. He named seven moons of Saturn and four moons of Uranus, the planet his father had only recently discovered. Making admirable use of John's unpublished correspondence, diaries, and notebooks, Buttman covers his extensive astronomical observations at Cape Town in South Africa, his pioneering work in photography and in physical optics in Britain, his unhappy experiences as Master of the Mint, and much more.

This book introduces an analytic method to describe the shadow of black holes. As an introduction, it presents a survey of the attempts to observe the shadow of galactic black holes. Based on a detailed discussion of the Plebański–Demiański class of space-times, the book derives analytical formulas for the photon regions and for the boundary curve of the shadow as seen by an observer in the domain of outer communication. It also analyzes how the shadow depends on the motion of the observer. For all cases, the photon regions and shadows are visualized for various values of the parameters. Finally, it considers how the analytical formulas can be used for calculating the horizontal and vertical angular diameters of the shadow, and estimates values for the black holes at the centers of our Galaxy near Sgr A* and of the neighboring galaxy M87.
