Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity - but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: Is there life, intelligent or otherwise, on other planets?

Now in its fourth edition, this low-cost astronomy audio-textbook is designed for a one-semester introductory astronomy course aimed at non-science majors and future teachers. This new edition brings the latest astronomical discoveries together with cutting-edge teaching and learning strategies designed specifically to improve student learning and retention.

At the two four-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015, they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected, and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a powerful new path to understand the workings of the universe.

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?

In the aftermath of an asteroid impact, Earth’s power grid is damaged nearly beyond recovery. The survival of our world may well depend on energy sources collected from an abandoned undersea settlement beneath the icy surface of Enceladus. Earth-raised Colonel Carter Rhodes, in charge of Earth’s recovery efforts, calls upon Gwen Baré, a Venusian engineer, to regain control of the deserted moon outpost and collect fuel for Earth’s collapsing power grids.

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.

Great Heroes and Discoveries of Astronomy takes you around the world and across time in search of the unsung heroes who, in many ways, are just as important to the story of astronomy as Hubble, Einstein, and Sagan. Whether they stood on the shoulders of giants or themselves offered shoulders for giants to stand on, the heroes of astronomy you’ll meet in these 24 lessons are a collective of the brightest and most daring minds in science.

Are you puzzled by pulsars? Baffled by black holes? Bewildered by the big bang? If so, here are succinct, crystal-clear answers to more than 100 of the most significant questions about the essential nature of the universe - questions that have fired the imagination since the beginning of history. Over the course of this fantastic voyage, the origins, the discoveries, and the stunning achievements of astronomy will unfold before your eyes

New York Times best-selling author Deepak Chopra joins forces with leading physicist Menas Kafatos to explore some of the most important and baffling questions about our place in the world.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

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.

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.

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.

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.

When ancient people first sought to explain the mysteries of their own lives, they looked to the heavens. There, they saw a perfect reflection linking them directly with an omniscient universe. The study of the stars and the study of the psyche comprised a single science - astrology - that led C. G. Jung to describe astrology as "the first form of psychology". Visionary Activist Astrology escorts you through the mists of time to our own century, when science has verified what ancient people knew instinctively.

In 2017, Avi Loeb, Chair of Harvard's Astronomy Department, went public with a theory that shook the scientific community - our solar system has been visited by advanced alien technology. His provocative and persuasive argument (and internationally bestselling book Extraterrestrial) has opened thousands of minds to the existence of intelligent life beyond Earth. This book tackles the huge question of what happens next?

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

Every year, 200 experts across machine learning, automation, robotics, and space arrive in Palm Springs for MARS to share new ideas about how these four fields will shape our future. TV host and maker of things Adam Savage (MythBusters) takes listeners deep inside the MARS conference. In interviews with more than a dozen leading scientists and thinkers, Savage explores the mind-blowing and often misunderstood ways in which science and innovation are transforming the way we live, work, and play.
