Showing results for "Extraterrestrials" in Science

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.

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?

This series on Extraterrestrials dives into the intriguing world of alien life, from ancient beliefs and modern sightings to scientific exploration and cultural portrayals. Starting with the historical roots of extraterrestrial theories, it explores famous UFO incidents, the search for life within our solar system, and accounts of alien abductions. The series also examines how science fiction has shaped our perceptions of aliens and discusses the future of humanity’s quest to find intelligent life beyond Earth, blending fact, folklore, and speculative science to uncover the mysteries of the ...

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...

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.

Witty and thought provoking, two Vatican astronomers shed provocative light on some of the strange places where religion and science meet. “Imagine if a Martian showed up, all big ears and big nose like a child’s drawing, and he asked to be baptized. How would you react?” —Pope Francis...

A leading astronomer and gifted teacher takes readers on a wondrous tour of how science confronts the big questions—about the universe’s origins, destiny, and fundamental nature—and how it contends with the limits of our knowledge Humans have learned a lot about the world around us and the...

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 engaging memoir reveals the true story of the Search for ExtraterrestrialIntelligence (SETI), and discloses what we may very soon discover. Chronicling the program’s history with insight and humor, SETI senior astronomer Seth Shostak assures us that if there is sentient life in the universe, we are within decades of picking up its signal.

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.
