Astronomer Carl Sagan can be said to have launched the ecospiritual/religious naturalist trajectory with this book, upon which the TV series was based, later writing: “A religion that stressed the magnificence of the universe as revealed by modern science, might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths. Sooner or later such a religion will emerge.”

Two seminal quotes: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” “We are a way for the cosmos to know itself.”

The subtitle of this book says it all. As a planetary scientist for NASA’s Jet Propulsion Laboratory, Yeomans’ job was to plot the courses of known and newly-discovered NEOs – that is, asteroids and comets that in space terms come close to Earth’s orbit – and determine if and when they might be on a collision course with our planet. With more than 25,000 known NEOs orbiting around up there, it’s not an easy task. But Yeomans makes the crucial point: it’s not the space rocks we know about that pose the biggest threat, but rather the thousands and thousands of large near-Earth asteroids we don’t know about that are the greatest danger. It’s not like the movie Armageddon; it would take years to develop a space mission to deflect or destroy an incoming asteroid, so it’s crucial that we find and track them – as Yeomans says, before… show more.

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. 

There can be no question greater than “Is there life outside the Earth?”. Sara Seager places her own search for planets outside the Earth - almost 5000 planets in other solar systems have been discovered in the past three decades, including Earth-like bodies - against her own life story and struggles as a scientist weathering the unexpected loss of a spouse and the raising of her two young sons. Astronomers estimate there are billions of undiscovered planets just in our Galaxy. Seager paints our very own Earth as a bright point of community and connection in the vastness of space as she gives a first-person account of the technical challenges of seeking other planets and life elsewhere.

“Are we alone?” An age-old question that we may never answer. Andrew May walks us through the scientific study of whether there might be life elsewhere in the universe, and how we might identify it. And by “scientific study,” I mean actual scientific investigations, not wishy-washy sci-fi fluff. The book is both inspiring and terrifying, because the immense distances in space and time make you realize that intelligent life is both incredibly insignificant and incredibly precious.

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.

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.

Larry Niven (like CJ Cherryh) is a Grand Master of science fiction and no stranger to creating unique alien creatures and societies. But the Pak aliens are one of his weirdest creations of all.

I won’t spoil the surprise, but the Pak are truly unique amongst science fictional aliens, and the Hugo-nominated book–much like The Pride of Chanur–is a non-stop chase across space with the Pak demonstrating time and again that humanity is no match for them and that they could, in fact, be our deadliest threat.

I read this book many years ago, and it’s stayed with me as a great example of alien SF.

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.

So you want to find aliens. But where to begin? Digging up microbial neighbors on Mars? Encountering big-brained, tentacled beings in flying saucers? Searching for far-flung habitable exoplanets?

This compilation of essays from astrobiologists, AI experts, psychologists, planetary geologists, and NASA scientists (plus more!) gives the alien-hunter a well-rounded, thoughtful start for their search.

Some of the essays will leave you laughing out loud; others will remind you how much we still have to learn about the universe. I came away feeling both smarter and smaller, and I enjoyed every minute of it.
