Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes.

We understand the stars at a much deeper level, not as legendary figures connected with constellations, but as engines of matter, energy, and the raw material of life itself. The Life and Death of Stars introduces you to this story in 24 half-hour lectures that lead you through the essential ideas of astrophysics - the science of stars. Your guide is Professor Stassun, an award-winning teacher and noted astrophysicist. He provides lively, eloquent, and authoritative explanations at a level suitable for science novices as well as for those who already know their way around the starry sky.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

What is consciousness? Why are we here? Where did it all come from - the laws of nature, the stars, the universe? Humans have been asking these questions forever, but science hasn't succeeded in providing many answers - until now. In The Grand Biocentric Design, Robert Lanza, one of Time magazine's "100 Most Influential People", is joined by theoretical physicist Matej Pavšic and astronomer Bob Berman to shed light on the big picture that has long eluded philosophers and scientists alike.

Many of us on Earth live in a home with a street address, city, and zip code. But we have another address, which astronomers and astrophysicists refer to as our "cosmic address": Earth, Solar System, Milky Way, Local Group, Virgo Supercluster, the Universe. Consider the vast scales that our cosmic address spans. Understandably, it's hard for our brains to truly imagine it. Our galaxy, The Milky Way, is populated with somewhere between 100-400 billion stars, one of which is our Sun, an average, run-of-the-mill star.

Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. NASA plans to send astronauts to Mars orbit by the 2030s. SpaceX wants to go by 2024, while Mars One wants to land a permanent settlement there in 2032. As we gear up for missions like these, we have a responsibility to think deeply about what kinds of life may already inhabit the planet - and whether we have the right to invite ourselves in.

Você certamente já ouviu falar em estrela cadente, cometa, asteroides, mas sabe o que são cada um deles? Muito se fala que foi provavelmente um meteoro que extinguiu os dinossauros.

Neste audiolivro, serão explorados eventos bonitos, curiosos e intrigantes, como as auroras boreais, os eclipses solares e os lunares, além de diversas curiosidades sobre as constelações e as estrelas. Tudo de forma simples e acessível.

Are we alone in the universe? This is one of the most profound issues facing mankind - and one of the unresolved questions that science may finally be able to answer in this century. These 24 mind-expanding lectures reveal the cutting-edge research leading scientists to believe that life is not exclusively the domain of Earth. Professor Close offers an unparalleled look at the subject of life and the mysteries that remain.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

For decades, books, movies, television shows, and conspiracy theories have speculated about the existence of life on other planets. But how possible is it that we are alone in the universe? How likely is it we’ll find a habitable, Earth-like planet? How come we have not already seen signs of extraterrestrial life? Join astrophysicist Sarah Rugheimer to reveal what we know about detecting life on other planets.

How did life begin on Earth? Does it exist elsewhere? What would those life forms be like? These fundamental questions about the nature of life and our own cosmic significance are endlessly fascinating. In this book, we present several theories on the origin of life, some of its extreme and surprising forms, and the ongoing search for signs - or sentience - on distant worlds.

Are the physical laws of our universe finely tuned, such that life can exist? What does this imply about how our universe formed? Questions like these are examined in Nature's Balancing Act, presented for a wide audience.

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.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.

This audiobook narrated by Juliet Stevenson shares the story of a world-renowned physicist who seeks gravity’s true nature and finds wisdom in embracing its force in her life.

Lisa Kaltenegger begibt sich auf Spurensuche nach den sogenannten Exoplaneten und erklärt, unter welchen Umständen außerirdisches Leben möglich ist. Die Wissenschaft ist näher dran als je zuvor, das Rätsel um Leben im All zu lösen. Lisa Kaltenegger, die renommierte Astrophysikerin und Astronomin, gewährt einen Einblick in die neueste Forschung und nimmt uns mit auf eine Entdeckungsreise durch die Milchstraße.

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. 

Everywhere he goes, crowds gather to meet Buzz Aldrin. He's a world-class hero, a larger-than-life figurehead, and the best known of a generation of astronauts whose achievements surged in just a few years from first man in space to first men on the moon. Now he pauses to reflect on and share what he has learned, from the vantage point not only of outer space but also of time: Still a nonstop traveler and impassioned advocate for space exploration, Aldrin will be 86 in 2016.

Some 4.6 billion years ago, a planetary system was born from a disc of gas and dust surrounding a young star. Specks of dust, pushed into dense clumps, collided, stuck together, and grew. While the gas disappeared, the growing bodies clashed in a final violent phase, leaving a series of planets, and much debris.

The question of man’s place in the extended universe has been pondered by every known culture since the beginning of recorded history. Naturally, as technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. While incidents like the one at Roswell led to conspiracies and a craze among those who insisted the government was hiding proof of extraterrestrials’ existence, governments across the world were actually secretly studying UFO sightings by the mid-20th century.
