Humanity's relationship with black holes began in 1783 in a small English village, when clergyman John Michell posed a startling question: What if there are objects in space that are so large and heavy that not even light can escape them? Almost 250 years later, in April 2019, scientists presented the first picture of a black hole. Physicist Jonas Enander has traveled the world to investigate how our understanding of these elusive celestial objects has evolved since the days of Michell.

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.

For Irwin Shapiro, science starts with questions. This book provides a broad and entertaining survey of major scientific discoveries that have changed our views of nature and, in turn, spawned further questions. Shapiro, an award-winning scientist and beloved teacher, separates his inquiry into three parts: looking up at the universe; looking down at the earth and its fossils; and looking in at the story of life. His framework encourages listeners to view science as a detective story—to observe and question nature and natural phenomena, and to base all conclusions on scientific evidence.

Written in simple and accessible language, this nontechnical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

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.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.

Humanity has long looked to the sky and marveled at the world around us. We've wondered why the world is the way it is and whether it has to be that way. And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

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.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

Throughout history, when threatened by wildfires our only defense was to pray for rain and run—until aircraft changed the way we fight fires. Beginning with the Canadian "H-Boats" in 1924, aircraft have become indispensable in detecting and extinguishing wildfires. Fire Eaters tells the incredible stories of the Ontario Provincial Air Service, the first government aerial fire suppression organization in history; one of its pilots, Carl Crossley, who invented the water scoop-up and drop-off system; and the Canadair CL-215, the first purpose-built water bomber.

Space exploration is as much a story of leadership and teamwork as it is a story of exploration and discovery. Leadership Moments from NASA delves into the organizational culture, leadership styles, and insights of NASA senior executives spanning five decades of human spaceflight, to share the lessons they learned from critical moments where they took on seemingly insurmountable challenges.

In this one-of-a-kind memoir, Jack Clemons - a former lead engineer in support of NASA - takes listeners behind the scenes and into the inner workings of the Apollo and Space Shuttle programs during their most exciting years. Discover the people, the events, and the risks involved in one of the most important parts of space missions: bringing the astronauts back home to Earth. Clemons joined Project Apollo in 1968, a young engineer inspired by science fiction and electrified by John F. Kennedy's challenge to the nation to put a man on the moon.

Aerospace engineering is the engineering of flight, and involves the design and operation of planes and space vehicles. It draws on the expertise of various branches of engineering and science and produces some of the most complex and technologically advanced vehicles ever conceived, such as spacecraft and the rovers used on the surfaces of the Moon and Mars. The field is central to many aspects of global communications and monitoring day to day through the vast array of satellites that orbit the Earth.

The Ghost in the Telescope is an insider's account of the Herschel Space Observatory, which was launched to answer two of the biggest questions in astronomy: How were the stars and galaxies born? Written in an engaging manner for a general audience, this book tells the stories of the telescope itself, the discoveries it made, and the engineers and astronomers who built and used it.

The violent birth of the universe was only the first bang of a very bumpy ride. This unfathomably cacophonous beginning has spawned blasts, implosions, cosmic cannibalism, collisions, and countless other fleeting energetic events punctuating the cosmos. Although often brief, these transient phenomena pack a powerful punch. Astronomer and science writer C. Renee James introduces us to her colleagues around the world, who are using pioneering research techniques to explore everything from the very first explosions in the universe to the dark energy that could destroy it all.

Mars, a mysterious dust-ridden place, is most like Earth in its climate and seasons. Of all the possible destinations in space to travel, Mars is the most likely for humans to reach. According to esteemed scientist Louis Friedman, it may be the only destination outside the moon to ever see human footprints. Far from diminishing our future in space, Human Spaceflight lays out a provocative future for human space travel. The noted aerospace engineer and scientist says that human space exploration will continue well into the future, but space travel by humans will stop at Mars.

Christopher A. Roosa grew up the eldest son of Apollo 14 astronaut and command module pilot Stuart A. Roosa. As a child of the space program, Christopher had a ringside seat at the dinner table of one of twenty-four Americans who had either entered lunar orbit or landed on the moon.

Is the human body built for Mars? NASA's studies on the International Space Station show we need to fix a few things before sending people to the Red Planet. Astronauts go into space with good vision and come back needing eyeglasses. Cognition and DNA expression could be affected for years. And then there's the discomfort of living in a tight space with crewmates, depression, and separation from the people you love.

Les Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges that we need to overcome in order to realize tomorrow's possibilities.

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.
