Book cover of The Promise of Space

Ian Ridpath Author Of Star Tales

From my list on that have inspired my writings on astronomy and space.

Why am I passionate about this?

I am an author, editor, lecturer, and sometime broadcaster on astronomy and space. My early interest in the possibilities of extraterrestrial life and interstellar communication led me to write my first books, Worlds Beyond (1975) and Messages from the Stars (1978). This interest also led me to investigate UFO sightings, but I soon realized that their explanation lies in human misperception and not ETs. My investigation and explanation of the famous Rendlesham Forest UFO case of December 1980, widely regarded as one of the top-ten cases worldwide and sometimes known as Britain's Roswell, can be found hereIn conjunction with the outstanding Dutch celestial cartographer Wil Tirion, I have produced two standard observing guides for amateur astronomers.

Although Arthur C. Clarke is usually regarded primarily as an author of science fiction (think 2001, Rendezvous with Rama) he was also a masterful exponent of science fact. Written at a time when humans were still preparing to land on the Moon, this book opened the door to the vistas of outer space for this budding author. A man generations ahead of his time, Clarke would have been as disappointed as any at our slow rate of progress in space exploration since the Apollo Moon landings. An uplifting view of our technological future, some of it still to come, from a true visionary.

Why should I read it?

1 author picked The Promise of Space as one of their favorite books, and they share why you should read it.

What is this book about?

"When Clarke wrote this volume in 1968, humanity stood on the brink of bursting forth from this ball of dirt into the universe. It is full of hope for the Space Age to come, and a rather sad thing to read today. Still, it's a great book, crammed with technical diagrams, astronomical photographs, and good solid science."

Carl Sagan was that most unusual of creatures: a top scientist who was also a lyrical writer. In an era when scientists were still wary of dealing with the press – an aversion that he helped overturn – his books were particularly influential in promoting the search for extraterrestrial life, both on the planets of our own Solar System (notably Mars) and on planets of other stars. In nearly 40 short, varied essays, The Cosmic Connection outlines our links with the cosmos around us, raises the possibility that we are not alone, and discusses what we might do if an extraterrestrial contact were to be received.

Why should I read it?

1 author picked Carl Sagan's Cosmic Connection as one of their favorite books, and they share why you should read it.

What is this book about?

In 1973, Carl Sagan published The Cosmic Connection, a daring view of the universe, which rapidly became a classic work of popular science and inspired a generation of scientists and enthusiasts. This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid, lyrical style, he discusses many topics from astrophysics and solar system science, to colonization of other worlds, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as…


Book cover of Star Names: Their Lore and Meaning

John M. Saul Author Of What the Stork Brought: African click-speakers and the spread of humanity's oldest beliefs

From my list on the origins of humanity's earliest beliefs.

Why am I passionate about this?

As a geologist, I met and shared meals – occasionally under the stars – with individuals with strikingly different backgrounds. In time I realized that, whatever their DNA, they all shared certain beliefs, that the happy dead eventually go upward, for example, even if they start by going down or out to the horizon. Eventually, I concluded that the entire human adventure began in a single moment the day one of our forebears asked another "What shall we do about death?" and was understood. Humans have a single genetic heritage; we also have a single cultural heritage.

Allen (1838-1906) was described as a "walking encyclopedia" by people who knew him. It was only after acquiring a reprint of his great book, a decade before the internet, that my own research into ancient cosmology took off. Star Names was first published in 1899 and as Wikipedia notes "there is no direct modern equivalent." As is the case with the internet, large sections can also be plucked out and read for pleasure.

2 authors picked Star Names as one of their favorite books, and they share why you should read it.

What is this book about?

Here is an unusual book for anyone who appreciates the beauty and wonder of the stars. Solidly based upon years of thorough research into astronomical writings and observations of the ancient Chinese, Arabic, Euphrates, Hellenic, and Roman civilizations, it is an informative, non-technical excursion into the vast heritage of folklore and history associated with the heavenly bodies.
From his studies of the writings of scores of ancient astronomers, the author has come up with a fascinating history of the names various cultures have given the constellations, the literary and folkloristic uses that have been made of the stars through the…

I love books full of facts and figures, and for astronomers, this is one of the best. Now in its fourth edition (the first appeared in 2005), Universe (subtitled The Definitive Visual Guide) harnesses a team of expert writers with Dorling Kindersley’s designers, editors, and researchers to produce a sumptuously illustrated review of the Universe from the Earth to the Big Bang, including extensive sections on the night sky and how to view it. Dorling Kindersley’s books are natural successors to the great Reader’s Digest reference books of my childhood. If you want an encyclopedia of the Universe, this is the one to have.

I am an experiencer who has had a lot of experiences with otherworldly beings for the last several years now, and I am also an inventor in my own right with one patent. I feel I have the ability to pay attention to detail, and I'm very analytical when it comes to making sense of things I can read, see, and hear. In my book, I give detailed explanations of my experiences from my encounters, and I am a very practical person, where I have the tendency to analyze mostly everything I do.

Marvin's book list on exploring UFOs and alien topics

Marvin Harding Why Marvin loves this book

I highly recommend this book because it takes a uniquely scientific yet imaginative approach to the question of extraterrestrial life.

Instead of relying on speculation alone, Pickover blends biology, physics, and astronomy to explore what alien life might realistically look like, how it could evolve, and the environments it might inhabit. He examines possibilities ranging from microbial organisms to advanced civilizations, grounding each scenario in scientific principles while still leaving room for wonder.

This makes the book both intellectually stimulating and accessible, appealing to readers who want more than just UFO anecdotes—they want a thoughtful exploration of life beyond Earth.

If extraterrestrials ever landed on Earth, they would find us extremely strange. Their first intimation of our existence might well be a Super Bowl broadcast or a stray transmission from the Playboy channel. But, of course, they might seem equally strange to us. How strange? Their senses could be entirely different from ours,they might see in the infrared or hear" radio waves.What would aliens look like? An intelligent octopus-like creature is certainly plausible. What about odd numbers of limbs,a three-legged alien with three arms and three eyes? What about an entire planet of immobile, silicon-based trees" that communicate with each…

Marvin's book list on exploring UFOs and alien topics

Marvin Harding Why Marvin loves this book

I highly recommend this book because it is a groundbreaking investigative book that compiles credible testimonies from military, aviation, and government figures to argue that UFOs represent a genuine, unexplained phenomenon worthy of serious study.

The book begins by establishing its journalistic foundation: Kean emphasizes that while most UFO sightings can be explained as misidentifications, a small percentage—roughly 5–10% remain unexplained even after investigation. These cases often involve highly trained observers such as military pilots, radar operators, and government officials.

Marvin's book list on exploring UFOs and alien topics

Marvin Harding Why Marvin loves this book

I highly recommend this book because it is one of the most influential and thought‑provoking books ever written on the UFO phenomenon, blending personal experience with cultural impact.

Strieber recounts his chilling encounters with mysterious “visitors” in vivid detail, describing moments of paralysis, lost time, and hypnotically recovered memories that challenge the boundaries between dream, reality, and the unknown. His narrative is not just about alien abduction—it's about confronting the limits of human understanding, exploring whether these beings are extraterrestrial, interdimensional, or something entirely different. 

I am an experiencer myself. Although our stories are very different, I can say that extraterrestrials are real without question, and his book is a good read!

Communion is the iconic classic in which Whitley Strieber describes his 1985 close encounter experiences. This book, which fundamentally changed the way we understand close encounters and alien abductions, is presented here with a new introduction by the author.


The message of Communion, that something unknown is really happening to people but that we have not studied it enough to understand it, remains as timely now as it was in 1987 when the book was first published. And Whitley Strieber's riveting account of what he experienced, along with his relentless and expert pursuit of the reality behind the experience, is…

Marvin's book list on exploring UFOs and alien topics

Marvin Harding Why Marvin loves this book

I highly recommend this book because it is a thought-provoking exploration of UFOs not as physical spacecraft, but as powerful cultural myths that reveal deep truths about human psychology and spirituality. 

Halperin, a scholar of religious studies, argues that UFOs are “real” in the sense that myths are real. They embody collective fears, desires, and questions about our place in the universe.

By David J. Halperin ,

Why should I read it?

2 authors picked Intimate Alien as one of their favorite books, and they share why you should read it.

What is this book about?

A voyage of exploration to the outer reaches of our inner lives.

UFOs are a myth, says David J. Halperin-but myths are real. The power and fascination of the UFO has nothing to do with space travel or life on other planets. It's about us, our longings and terrors, and especially the greatest terror of all: the end of our existence. This is a book about UFOs that goes beyond believing in them or debunking them and to a fresh understanding of what they tell us about ourselves as individuals, as a culture, and as a species.

Book cover of UFO: The Inside Story of the US Government's Search for Alien Life Here-and Out There

Neil Nixon Author Of UFOs, Aliens and the Battle for the Truth: A Short History of UFOlogy

From my list on making you an expert on UFOs.

Why am I passionate about this?

I’ve been writing for publication since I was a student, crudely the writing has been a way of medicating the fact I’m incurably curious about a range of things and I’ve also suffered from an over-production of ideas my whole life. Wrestling this under control into writing and live speaking where the subjects must fit within a title, word limit, or running time for a talk has been helpful, beyond which the whole writing career has been a trade off between things I’ve chosen to do because they matter a lot to me, and the occasional accepting of an offer I thought too good to refuse.

Neil's book list on making you an expert on UFOs

Neil Nixon Why Neil loves this book

This is hefty, recent, authoritative, and well written (the author’s CV includes a Pulitzer Prize nomination).

Over a lengthy historic account, he spins the twin stories of the search by scientists for extraterrestrial life and the – usually – amateur search by ufologists for evidence to support their claims that aliens are already visiting us. Garrett Graff explores the contradictions.

He is clear and concise on the strength and weakness each side’s efforts, and insightful in those moments when both sides have briefly collaborated. For a beginner to the subject who wants the shortest route to becoming truly knowledgeable, this is the perfect primer.

For as long as we have looked to the skies, the question of whether life on Earth is the only life to exist has been at the core of the human experience, driving scientific debate and discovery, shaping spiritual belief, and prompting existential thought across borders and generations. And yet,…

From my list on UFOs to read whether you believe or not.

Why am I passionate about this?

I’ve been fascinated by UFOs since I was a kid, but it wasn’t until I met a Martian in 2016 that I started writing about them. To be more specific, I stumbled across a bizarre 1926 article about a man in telepathic communication with a Martian named Oomaruru. I then delved deeper into the beliefs about intelligent Martians at that time. It led to my writing The Big Book of Mars, which touched on the UFO phenomena in the 1940s and ‘50s. But knowing there was so much more to explore, I began writing We Are Not Alone, which is now my 8th book.

Marc Hartzman Why Marc loves this book

This was the first 1950s “contactee” book I read while researching my book. And it’s a fun one.

Contactees were a group of people in the fifties and sixties claiming to have been in contact with aliens—usually Venusians. Fry gives his account of stumbling upon a flying saucer in New Mexico in 1950 and flying to New York and back in 30 minutes. He flew alone, guided remotely from an alien far above.

In his conversations with the extraterrestrial being, he learned that they were visiting our planet to warn us about the dangers of the atomic age and the possible destruction of earth. It’s entertaining, and regardless of your beliefs, the alien makes a fair point.
