68 Books Like The Science Of Aliens

While in the 1960s Carl Sagan and Frank Drake, based on a simple equation (“Drake’s equation”) concluded that intelligent life is abundant in the Galaxy, with as many as a million such civilizations with which we might be able to communicate, the thesis of this book is that intelligent life is exceedingly rare in the Universe.

The authors do not argue that life itself is rare. Their thesis is that simple life, such as single-celled organisms like bacteria, may have developed on billions of planets in the Galaxy. But that, on the other hand, animal life on land (multicellular creatures, able to move around) is exceedingly rare. And that these animals developing intelligence is still very much rarer.

The arguments which the authors put forward are based on what we know from the history of life on Earth in connection with the very special position of Earth in our planetary… show more.

I highly recommend this book because it offers one of the most balanced and skeptical examinations of the UFO phenomenon available.

Unlike many books that lean heavily into sensational claims, Sheaffer applies the scientific method and critical thinking to famous cases, exposing how misidentifications, cultural myths, and selective reporting often fuel the UFO narrative.

His work provides readers with a broad overview of major sightings and trends in ufology, while also highlighting the importance of questioning extraordinary claims and demanding credible evidence.

While researching Mona Lisa: A Life Discovered, I rented an apartment a few blocks from a house where Galileo lived in Florence. I could stand outside its door every day, but this book transported me inside—not just a building but a family, a home, and an era. 

Dava Sobel’s meticulous research reveals not just new dimensions of Galileo’s life and work as an intrepid scientist but the often hidden realm inhabited by his daughter. Illegitimate and unmarriageable, she entered a convent at age 13 to live in poverty and simplicity. And yet, as her letters demonstrate, Sister Marie Celeste’s soul and spirit soared. The ending—which I dare not spoil—has haunted me since my first reading decades ago.

A recognized genius in his own right, Isaac Asimov takes us on an easy-to-read tour-de-force through the most basic elements that make up everything. Spoiler Alert: It’s not just sugar and spice. Anyone who has the slightest curiosity regarding astronomy, diet, health, cooking, physics, or chemistry should read this fabulous, easy-to-understand guide. It reveals what you and I are really made of. All that “ashes to ashes, dust to dust” stuff becomes crystal clear.

It is full of interesting anecdotes ranging from why the Hindenburg was never a great idea, the water that quenches fire is composed of two elements that explode when separately exposed to flame, and how life uses oxygen to function and survive. The Building Blocks of the Universe are just what Isaac Asimov says they are….the foundations of everything that exists.

The stars have captivated hunter-gatherers, artists and astrologers, sages and scientists, romantics, and civilizations since the beginning of human time. 

In this book we encounter the twenty-one brightest stars visible from earth and dig into their remarkable secrets. Did you know some giant stars spin so fast they flatten out like eggs? There are stars that pulse back and forth like beating hearts? And some stars are cosmic interlopers passing through our Milky Way galaxy on their way back into the void of forever space. This is my go-to book when I want to refresh my imagination with wondrous facts about the stars blazing overhead. It should be within handy reach of every star-struck observer, camper, or poet.

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.

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!

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.

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.

I discovered Alastair Reynolds, who is now my favorite science fiction writer, by reading this book, which was a mind-opening experience. I especially enjoy his combining a kind of “film noir” sensibility with realistic science ideas (the latter is not surprising since he has a Ph.D. in astronomy.) 

This first novel in his series is an excellent way to delve into his marvelously imagined Universe, where humanity exists in a number of genetically modified variants, and intelligences have to contend with ancient and powerful machines that deem organic life too war-like to be permitted to live.
