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.

What if reality is far stranger than you've ever imagined? What if the world around you is not exactly what it appears to be? From recurring patterns in nature to the mysteries of consciousness, countless questions continue to challenge our understanding of existence.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials? 

Em outubro de 2017, cientistas de um dos maiores observatórios espaciais do mundo — localizado no topo de um vulcão dormente no Havaí — detectaram um objeto transitando por nosso sistema solar. A primeira hipótese foi a de que se tratava de um mero asteroide, como tantos outros que cruzaram e seguem cruzando nossa galáxia. Mas os dados coletados pelo telescópio Pan-STARRS1 revelaram detalhes curiosos, e bem anômalos, no comportamento desse visitante.

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.

The search for Planet B. Why Earth is so special? And where are the aliens? Dr Matt Agnew takes us through this fun, information-packed, fascinating look at life in space. Sit back, relax, let your imagination run wild and enjoy this scientific journey. With a PhD in astrophysics, Dr Matt is a...

Life in Space explores the many aspects and outcomes of NASAs research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASAs work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush's Vision for Space Exploration.

Крис Хэдфилд провел в космосе почти 4000 часов и считается одним из самых опытных и популярных астронавтов в мире. Его знания о космических полетах и умение рассказать о них интересно и увлекательно не имеют равных. Его видео в Интернете бьют рекорды просмотров. Однако эта книга не только о том, что представляет собой полет в космос и жизнь на орбите. Это история человека, который мечтал о космосе с девяти лет , но и смог реализовать свою мечту, хотя, казалось бы, шансов на это не было никаких. Это настоящий учебник жизни для тех, у кого есть мечта и стремление ее реализовать.

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.

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. 

Are we alone in the universe—or is life a cosmic inevitability? Life in the Cosmic Context goes beyond the conventional search for extraterrestrial biology, asking deeper questions about the very nature of life and our place in an immense, evolving cosmos. In this groundbreaking work, astrobiology becomes more than the science of life beyond Earth; it is a philosophical lens for reimagining what life itself can be. From the origins of life on Earth to the potential for entirely different biochemistries elsewhere, this book challenges listeners to rethink what is possible.

Your mattress. Your phone camera. The water from your tap. NASA made all of them better. Hidden in your home right now are dozens of technologies that began as solutions to the extreme challenges of space exploration. None of them were supposed to end up in your house. But here we are. If you’ve ever wondered why we spend money on space when there are problems to solve on Earth, this book provides the answer. The technologies developed to keep astronauts alive, healthy and productive have transformed life for billions of people here on Earth.

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.

As command module pilot of Apollo 17, the last crewed flight to the moon, Ron Evans combined precision flying and painstaking geological observation with moments of delight and enthusiasm. As a patriotic American in charge of command module America, Evans was nicknamed “Captain America” by his fellow crew members.

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.

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.

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...

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!
