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.

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?

A New York Times–bestselling astrophysicist and a Nobel laureate describe the quest to discover how and where the universe breathed life into matter For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists...

The story of the men and women who drove the Voyager spacecraft mission— told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries—11.3 billion miles away from the crew who built and still operate them, decades since their launch. Voyager...

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.

In this compelling and revealing examination, author Rupert Matthews looks afresh at key episodes of alien activity on earth, and sheds light on the many mysterious phenomena associated with it. From Roswell to Taizé, the book dissects fascinating eyewitness accounts of communication and contact with alien beings, as well as chilling cases of abduction. It also sifts through sinister evidence of government cover-ups. Alien Encounters is a gripping investigation of strange events that continue to spark fierce debate. If you doubt the existence of extra-terrestrials, prepare to be convinced.

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?

Is there other intelligent life in the universe, or are we all alone? Now you can explore this question through 17 compelling conversations with leading experts on extraterrestrial life. The prospect of alien intelligences has long captivated cosmologists, perplexed theologians, and provided rich fodder for science fiction writers. While we may doubt that the large-eyed, green-skinned figures of sci-fi films will one day descend to Earth in UFOs, it is far harder to reject wholesale the possibility that intelligent life - in some form yet unknown - exists.

Exogenesis: Hybrid Humans offers a deep dive into the strongest ever scientific evidence that supports the popular belief that Earth has been visited in prehistory, but goes even further, concluding that there is also compelling evidence of alien involvement with the human genome. The broader history of possible extraterrestrial contact is explored alongside a look at current events in the subject of alien disclosure with the result of highlighting evidence of a contact continuum that has continued since the dawn of humanity.
