On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference - a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.

The ordinary atoms that make up the known universe - from our bodies and the air we breathe to the planets and stars - constitute only 5 percent of all matter and energy in the cosmos. The rest is known as dark matter and dark energy, because their precise identities are unknown. The Cosmic Cocktail is the inside story of the epic quest to solve one of the most compelling enigmas of modern science - what is the universe made of? - told by one of today’s foremost pioneers in the study of dark matter.

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.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

Astronomy expert Tom Kerss offers complete advice from the ground up, introducing the world of telescopes, planets, stars, dark skies and celestial maps, explaining the best ways to plan your stargazing experience and the key things to look out for on specific dates throughout the year.

A dazzling tour of the universe as Einstein saw it. How did Albert Einstein come up with the theories that changed the way we look at the world? By thinking in pictures. Michio Kaku, leading theoretical physicist (a cofounder of string theory) and best-selling science storyteller, shows how Einstein used seemingly simple images to lead a revolution in science. With originality and expertise, Kaku uncovers the surprising beauty that lies at the heart of Einstein's cosmos

In researching one of history's greatest scientific quests, a mission to measure the Earth and define the meter, Ken Alder stumbled on a 200-year-old secret: The meter, it turns out, is in error. This is a story of two men, a secret, and a timeless human dilemma: is it permissible to perpetuate a small lie in the service of a larger truth?

This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-19th century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam and led to Copernicus's claim that the Earth is in motion.

Speaking with key leaders of the latest space programs and innovations, Rod Pyle shares the excitement and promise of this new era of exploration and economic development. From NASA and the Russian space agency Roscosmos, to emerging leaders in the private sector, Space 2.0 examines the new partnerships that are revolutionizing spaceflight and changing the way we reach for the stars.

What would it have been like to be an eyewitness to the Big Bang? In 2014, astronomers wielding BICEP2, the most powerful cosmology telescope ever made, revealed that they'd glimpsed the spark that ignited the Big Bang. Millions around the world tuned in to the announcement broadcast live from Harvard University, immediately igniting rumors of an imminent Nobel Prize. But had these cosmologists truly read the cosmic prologue or, swept up in Nobel dreams, had they been deceived by a galactic mirage?

Author of the New York Times best seller The Beginning of Infinity, David Deutsch, explores the four most fundamental strands of human knowledge: quantum physics, and the theories of knowledge, computation, and evolution - and their unexpected connections. Taken together, these four strands reveal a deeply integrated, rational, and optimistic worldview. It describes a unified fabric of reality that is objective and comprehensible, in which human action and thought are central.

This concise guide on the James Webb Space Telescope describes our most powerful modern space observatory’s place in an exciting new era of astronomy. The Webb telescope is the largest, most technically advanced and most expensive space observatory to date. Development began in 1996 for a launch initially planned for 2007 with a US$500 million budget. Finally launched in December 2021, the telescope was 14 years behind schedule and 20 times over budget. Such was the price of the next major step in astronomy and physics. Written to be accessible to all readers, the book describes Webb’s ...

Contrary to popular belief, death is not a moment in time, such as when the heart stops beating, respiration ceases, or the brain stops functioning. Death, rather, is a process - a process that can be interrupted well after it has begun. Innovative techniques, such as drastically reducing the patient's body temperature, have proven to be effective in revitalizing both the body and mind, but studies show they are only employed in approximately half of the hospitals throughout the United States and Europe.

The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

A stunning memoir from the astronaut who spent a record-breaking year aboard the International Space Station - a candid account of his remarkable voyage, of the journeys off the planet that preceded it, and of his colorful formative years. A natural storyteller and modern-day hero, Kelly has a message of hope for the future that will inspire for generations to come. Here, in his personal story, we see the triumph of the human imagination, the strength of the human will, and the boundless wonder of the galaxy.

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet. The rest is completely unknown. Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy”. This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize.

On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.

In Neil deGrasse Tyson’s delightful journey through the cosmos, his fictional character Merlin responds to popular questions asked by adults and children alike. Merlin, a timeless visitor from Planet Omniscia in the Andromeda Galaxy, has observed firsthand many of the major scientific events of Earth’s history.

Beneath the Night is a history of humanity, told through our relationship with the night sky. From prehistoric cave art and Ancient Egyptian zodiacs to the modern era of satellites and space exploration, Stuart Clark explores a fascination shared across the world and throughout millennia. It is one that has shaped our scientific understanding; helped us navigate the terrestrial world; provided inspiration for our poets, artists and philosophers; and it has given us a place to project our hopes and fears. In the stars, we can see our past - and ultimately, our fate.

Humans are pattern-matching creatures, and astrology is the universe's grandest pattern-matching game. In this refreshing work of history and analysis, data scientist Alexander Boxer examines classical texts on astrology to expose its underlying scientific and mathematical framework.
