Book cover of The Sirens of Mars: Searching for Life on Another World

Laura Krantz Author Of Is There Anybody Out There?: The Search for Extraterrestrial Life, from Amoebas to Aliens

From my list on the search for alien life.

Why am I passionate about this?

I was never going to hack it as a scientist. So I became a journalist instead. After all, both careers stem from a sense of wonder about the world and asking questions, looking for answers, and accepting that there might not be any. In 2018, I started my narrative podcast Wild Thing, which let me explore some of our weirder collective fascinations (like aliens) using science, history, psychology, and humor. I’d never aimed the podcast at kids, but I realized that all those big open-ended questions that I had about everything were the same kinds of questions that kids had - which really set me up to write the Wild Thing book series.

Laura Krantz Why Laura loves this book

Imagine for a moment that we found life on Mars.

That discovery would shake our world, change our outlook on the universe, and answer the question of whether we’re alone.

Sarah Stewart Johnson, a planetary scientist, has spent her life thinking about this possibility and delves into both her and our obsession with the Red Planet in this beautifully written book. Part memoir, part historical account, and part scientific exploration, this book made me want to ditch a career in journalism and take up astrobiology. You’ll never look at Mars the same way again.

What is this book about?

As a new wave of interplanetary exploration unfolds, a talented young planetary scientist charts our centuries-old obsession with Mars.

'Beautifully written, emotive - a love letter to a planet' DERMOT O'LEARY, BBC Radio 2

Mars - bewilderingly empty, coated in red dust - is an unlikely place to pin our hopes of finding life elsewhere. And yet, right now multiple spacecraft are circling, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium and Mare Sirenum - on the brink, perhaps, of a discovery that would inspire humankind as much as any in our history.

With poetic precision and grace,…

Book cover of A Brief History of Time

Eugene Terry Tatum Author Of Flat Space Cosmology: A New Model of the Universe Incorporating Astronomical Observations of Black Holes, Dark Energy and Dark Matter

From my list on science of universe (cosmology).

Why am I passionate about this?

My passionate scientific interest in cosmology began several decades ago as a Stanford student while moon-lighting as a cloud chamber photo scanner at the Stanford Linear Accelerator Center (SLAC). An initial interest in particle physics merged with an interest in cosmology because the Big Bang theory is about both. Developing a unique cosmology model and collaborating with other cosmologists around the world was a natural extension. Following numerous peer-reviewed scientific publications, our book summarizing them was one, as well. Taking a passionate interest in anything and sharing it with others is an important first step!

Eugene Terry Tatum Why Eugene loves this book

I love Stephan Hawking’s A Brief History of Time because it was the first book that inspired me to become a cosmologist. It is a terrific overview of the science behind the modern belief in the Big Bang and what has followed.

It is told with Hawking’s wry sense of humor and unique ability to make complex concepts understandable to the layperson and budding scientist, which I was at the time. It is a fantastic start for my readers of all persuasions.

7 authors picked A Brief History of Time as one of their favorite books, and they share why you should read it.

What is this book about?

Was there a beginning of time? Could time run backwards? Is the universe infinite or does it have boundaries? These are just some of the questions considered in an internationally acclaimed masterpiece by one of the world's greatest thinkers. It begins by reviewing the great theories of the cosmos from Newton to Einstein, before delving into the secrets which still lie at the heart of space and time, from the Big Bang to black holes, via spiral galaxies and strong theory. To this day A Brief History of Time remains a staple of the scientific canon, and its succinct and…


Book cover of Children of Time

Phil Bailey Author Of Kelvoo's Testimonial

From my list on first contact science fiction novels.

Why am I passionate about this?

Of all the intelligent species (both real and fictional), humans fascinate me the most. For me, it’s the creativity and diversity of humans that both divide and unite us. Our eternal struggle to understand one another and overcome our differences fascinates me. I love first-contact science fiction that lets us view the values and behavior of our own species through the lens of true outsiders. I find great value in these parables when they increase self-awareness of our identities and our effect on others.

Phil's book list on first contact science fiction novels

Phil Bailey Why Phil loves this book

As a big fan of xenofiction, I appreciated that large parts of the book were written from the perspective of non-humans. I loved the author’s imagination, which, while innovative, never strayed into the implausible.

I was very interested in the timespan of thousands of years and the concept of accelerated evolution, and I found the intelligent, massive spiders to be both creepy and fascinating. For me, Children of Time was a good page-turner and a great read.

Laura's book list on the search for alien life

Laura Krantz Why Laura loves this book

Fred was a pilot. He also was an avid ufologist. In October 1978, on a short flight in a private plane from Melbourne to King Island in Australia, Fred has a conversation with air traffic control and claims to see a large aircraft — a UFO — flying around him… until it vanishes. 

That is Fred’s last conversation with anyone as both he and his plane disappear, never to be found. Was it an alien craft? Pilot error? Weather phenomenon?

There are no answers in Krasnostein’s chapters about Fred. But the story and her lyrical writing left me thinking about the nature of belief, the fascination we have with UFOs, and why we want our alien encounters to be real. Why do we want to believe?

Book cover of Extraterrestrial: The First Sign of Intelligent Life Beyond Earth

Stephen P. Maran Author Of Astronomy for Dummies

From my list on space from someone with 35 years at NASA.

Why am I passionate about this?

I’ve studied space for 60+ years, including spotting Sputnik from atop 30 Rock for Operation Moonwatch; monitoring an exploding star for a PhD at University of Michigan, leading the Remotely Controlled Telescope project at Kitt Peak National Observatory, hunting pulsars from Arizona and Chile, and helping develop scientific instruments for the Hubble Space Telescope. I worked for 5 years at Kitt Peak and 35 years for NASA. As Press Officer (now retired) of the American Astronomical Society, I organized press conferences on many notable cosmic discoveries. Minor Planet 9768 was named Stephenmaran for me, but I haven’t seen it yet. What I have spotted are five exceptional books on space.  Enjoy!

Stephen's book list on space from someone with 35 years at NASA

Stephen P. Maran Why Stephen loves this book

The first known object from interstellar space, ʻOumuamua, plunged through the solar system and headed out again in 2017. It was seen by telescopes for just 17 days, enough to tell that it wasn’t as the saying goes, a bird, a plane, or Superman. Perhaps it was a space vehicle or other artifact from distant aliens, an older and superior civilization than ours. At least that’s what the brilliant Harvard astrophysicist Avi Loeb suggests. I think his theory is soundly based on the limited observational data, but that doesn’t make it true, and other astronomers won’t touch aliens with a ten-foot telescope. They offer alternative explanations none of which clearly fit the data but that smack less of science fiction. Inquiring minds should read the book and decide for themselves.

Wil McCarthy Author Of Beggar's Sky

From my list on peaceful alien contact.

Why am I passionate about this?

I’ve been a science fiction writer since I was old enough to read, and I’ve spent probably way too much of my life reading and writing and researching and thinking about aliens. I’ve worked in the aerospace industry, launching rockets to the moon and Mars and Saturn, and five of the books I’ve published have touched on alien life in one way or another. I’ve worked as a contributing editor for WIRED magazine and the science and technology correspondent for the SyFy channel, and I hold patents in seven countries, including 31 issued U.S. patents.

Wil's book list on peaceful alien contact

Wil McCarthy Why Wil loves this book

This nonfiction book takes a hard look at humanity’s various attempts to craft a universal language that might, just might, let us one day communicate with extraterrestrials.

What symbols could we use? What encoding? How would we start, and once we’ve started, what would we talk about?

These aren’t easy questions, and we probably still don’t have all the right answers, but I loved the way Oberhaus walked us through the work that has already been done and the directions that future work might take.

If we send a message into space, will extraterrestrial beings receive it? Will they understand?

The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we)…

Book cover of The Ancient Alien Question

Ken Goudsward Author Of Fermi's Paradox is Bullshit: The Evidence for Extraterrestrial Life

From my list on rational UFO stories.

Why am I passionate about this?

As a child, I was fascinated with astronomy but discouraged from investigating the UFO phenomenon due to religious reasons. Not until I was in my forties, did I begin to see the strange Biblical hints of what ended up in my writing my book UFOs In The Bible. Along the way, my research led me to diverse related topics including Sumerian mythology and astrobiology which have resulted in a few more books (and more to come). I see logic as a fundamental tool for this line of investigation, and so, I embrace books that engage with the evidence logically. I firmly believe we must all make room for experiencers to tell their stories without recrimination.

Ken Goudsward Why Ken loves this book

Philip Coppens is not afraid to take on even the weirdest of niches within the already weird realm of ufology and paleoarchaeology. He does so with an even keel and an unlimited curiosity. He doesn’t simply parrot what everyone around is saying, but he does examine their claims to see if they hold water. Like in most other aspects of life, there are grains of truth and bald-faced lies. Coppens attempts to separate the wheat from the chaff.

I am a retired university professor who taught creative writing at the Faculty of Philology, University of Belgrade, and a not-yet-retired author, although I have on several occasions solemnly stated that I have written my last prose book. I believe these two qualities make me competent to create a list of 5 books that I have reread the most often.

Zoran's book list on literary works that I keep rereading

Zoran Živković Why Zoran loves this book

This is, in my humble view, the best science fiction novel ever written. I have read it no less than ten times so far and intend to keep rereading it. What nowadays seems incredible is that it was written back in 1961, when most science fiction was still in its age of innocence, full of naïve assumptions about extraterrestrials and their malevolent ambitions.

It will be many years before the first ideas of benevolent aliens appear and even more before we fully realize Lem's wisdom from Solaris: there isn't going to be any First Contact because Others are neither bad nor good, but indifferent, as it is the planetary intelligent ocean on Solaris. We aren't still mature enough even for contacts with ourselves, let alone Others.

What is this book about?

When Kris Kelvin arrives at the planet Solaris to study the ocean that covers its surface he is forced to confront a painful, hitherto unconscious memory embodied in the physical likeness of a long-dead lover. Others suffer from the same affliction and speculation rises among scientists that the Solaris ocean may be a massive brain that creates incarnate memories, but its purpose in doing so remains a mystery . . .

Solaris raises a question that has been at the heart of human experience and literature for centuries: can we truly understand the universe around us without first understanding what…

Bernd Perplies Author Of Star Trek Prometheus: Fire with Fire

From my list on Star Trek novels that will warp you into hyperspace.

Why am I passionate about this?

I’ve been a Star Trek fan and storyteller all my life. The first stories I wrote at school, the first Star Trek episodes I watched as The Next Generation debuted on German TV. Many years have gone by since then. I watched hundreds of Star Trek episodes and professionally penned dozens of fantasy and science fiction novels for children and adults, like Drachengasse 13 (“Dragon’s Alley 13”, not translated) or Der Drachenjaeger (“Black Leviathan,” Tor Books). The culmination of both being a fan and a writer came in 2016 when, with Star Trek: Prometheus, I was allowed to add my own small part to the ever-growing Star Trek literary universe.

Bernd Perplies Why Bernd loves this book

Honestly, I couldn’t put this book down. I read Rogue Elements during a summer vacation on a lovely North Sea island and I had to force myself to have a break and go out for some bicycling and beach fun.

John Jackson Miller just had me hooked with his tale of dashing (but also sad and often drunken) ex-Starfleet officer Cristóbal Rios – introduced in Star Trek: Picard – living through a hilarious adventure while at the same time trying to find a new purpose in life after being cashiered out of his career because of some fishy diplomatic affair.

Grumpy gangsters, a dangerous woman, strange new crew members, and the hunt for a secret treasure keep Rios on the run throughout the whole novel.

C.S. Friedman Author Of Nightborn: Coldfire Rising

From my list on books for designing alien worlds.

Why am I passionate about this?

For as far back as I can remember I’ve been creating fantastic stories. My high school notebooks were filled with maps of warring interstellar empires, and my graduate school notes were interspersed with short tales set in distant universes. My first science fiction novel, In Conquest Born, was published in 1985, and since then, I’ve written 14 novels for DAW Books, both in fantasy and science fiction. I love the challenge of creating alien worlds so real that my readers feel immersed in them and using them to explore the darkest recesses of the human psyche. 

C.S.'s book list on books for designing alien worlds

C.S. Friedman Why C.S. loves this book

Need to design an alien species? If so, you won’t find a better resource than this one.

Kershenbaum does nothing less than attempt to identify universal principles governing all biological organisms and does a damned impressive job of it. Beginning with the question of whether the human concept of “evolution” would even exist on an alien world, he works his way up to detailed and insightful analyses of what types of life forms would likely evolve in different environments and how they might communicate and socialize.

This is pure brain food for any lover of science or science fiction, an intellectual exploration you won’t be able to put down. It’s in my top 10 list for books of any kind.
