In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

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. 

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.

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.

An entertaining tour of the seemingly simple formula guiding the search for extraterrestrial intelligence Cloudy with a Chance of Starships takes listeners on an irreverent expedition through the marvelous world of astrobiology, using as a guide the most important equation in science since E=mc2...

In Vera Rubin: A Life, Jacqueline Mitton and Simon Mitton provide a detailed, accessible overview of Rubin's work, showing how she leveraged immense curiosity, profound intelligence, and novel technologies to help transform our understanding of the cosmos. But Rubin's impact was not limited to her contributions to scientific knowledge. She also helped to transform scientific practice by promoting the careers of women researchers. Not content to be an inspiration, Rubin was a mentor and champion for hiring women faculty and honoring them with awards historically exclusive to men.

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.

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.

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.

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. 

Written for the general lay listener, The Living Universe explores how the latest scientific discoveries are rewriting what we thought we knew about space, planets, and the origins of life. We now know that the universe is filled with planets, not just around other stars but also traveling in the space between them, and that many of these carry life with them. Some of these wandering planets have almost certainly been captured by the Sun's gravity, changing not just the arrangement of planets in the Solar System, but also the development of life on our Earth.

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.

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.

A powerful reflection on life in isolation, in pursuit of the dream of Mars. In 2013 Kate Greene moved to Mars. On NASA’s first HI-SEAS simulated Mars mission in Hawaii, she lived for four months in an isolated geodesic dome with her crewmates, gaining incredible insight into human behaviour in tight quarters, as well as the nature of boredom, dreams and isolation that arise amidst the promise of scientific progress and glory. 

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. Mas o que são as tais chuvas de meteoros? É possível prevê-las? E a Lua atua nas marés? Como? Entender o céu nos ajuda a entender o dia a dia da Terra. 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.

Humans have always been fascinated by the possibility of extraterrestrial life, often wondering if we are alone in the universe. Drawing on nearly fifty years as a leader in planetary exploration, Louis Friedman brings into focus the subject of extraterrestrial life, separating knowledge from conjecture, fact from fiction, to draw scientific and technical conclusions that answer this enduring question. Friedman argues that intelligent life is probably rare in the universe but that simple life is likely abundant on millions or billions of planets waiting now to be discovered.

Everywhere light goes, It has found that darkness is already there. Darkness is the natural state of the universe. For a star to be born, it takes an astounding number of possibilities to become a reality. From this unlikely alignment, we now have trillions of stars! Thankfully stars would progress to give us light, life, and an observable universe. No one knows how many stars exist, but we will tour a handful of the most famous in our known universe. Sit back and enjoy the world of outer space that spreads before you. Each constellation and luminary has a story that you won’t want to miss!

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.
