Wilson Literary Science Writing Award “Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected.” —Alan Lightman, New York Times bestselling author of Einstein’s Dreams and Searching for Stars on an Island in Maine Harvard’s top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars—and to think critically about what’s out there, no matter how strange it seems.

Winner of the 2019 Phi Beta Kappa Award for Science "A valuable perspective on the most important problem of our time." —Adam Becker, NPR Light of the Stars tells the story of humanity’s coming of age as we realize we might not be alone in this universe. Astrophysicist Adam Frank traces the question of alien life from the ancient Greeks to modern thinkers, and he demonstrates that recognizing the possibility of its existence might be the key to save us from climate change. With clarity and conviction, Light of the Stars asks the consequential question: What can the likely presence of life on other planets tell us about our own fate?

RESISTANCE IS ALL For years, writers and filmmakers have speculated about the possibility of the Earth being invaded by aliens from another planet. But what if the aliens have been watching us, infiltrating us via human collaborators, or even surgically altering themselves to look human? Occupied Earth is a groundbreaking anthology that explores the idea of what the world would look like years after its conquest. 20 years after a successful invasion by the Makh-Ra, humanity still exists, only it has become subservient to a race of occupiers who govern the devastated planet. But, as much at things continue with some sense of normalcy, something has happened in the Mahk-Ra’s empire. Earth, once considered a strategic beachhead of major importance to the Empire, has been downgraded in its value. Things are starting to degrade. Our planet is the last place any self-respecting Mahk-Ra officer wants to be assigned. Yet, despite everything, life continues. These stories bring us face to face with annihilation — and show how we can pull ourselves back from the brink. Featuring Rachel Howzell Hall, Lisa Morton, Matthew V. Clemens, Howard Hendrix, Nathan Walpow and more, OCCUPIED EARTH is coming. Stay safe. Stay strong. Survive at all costs.

A journey of stunning discovery by the author of Cloven Hooves. Humanity has been "rescued" from a toxic and dangerous Earth by the enigmatic Arthropalan and inserted into the fragile ecologies of twin alien worlds--where they must make no environmental impact.

Unmasking the mysteries of alien life on earth! Make mention of the word “alien” and it conjures images of black-eyed, large-headed, dwarfish beings that have come to be known as the Greys. Indeed, Greys have become a staple part of pop-culture, never mind just the field of UFO research. They’ve appeared in Steven Spielberg’s classic 1977 movie, Close Encounters of the Third Kind. They regularly popped up in The X-Files. And, of course, there are numerous people – all across the world – who claim to have been abducted by the Greys and subjected to intrusive medical experiments. Yet, before the 1950s, the Greys were nowhere in sight.

They all have one thing in common, however: the human race has encountered them, and we continue to do so today. Not just dozens, or even hundreds, but thousands of eyewitness experiences have been reported. Covering hundreds of extraterrestrial life forms in more than 40 thematic chapters, this absorbing look at the mysteries of aliens on earth includes ... the Space Brothers: long-haired, very human-looking ETs the fiendish Reptilians: seven-to-eight-foot-tall predatory shapeshifters Men in Black beings: extremely pale-skinned, tall, and with huge eyes Black-eyed Children: anemic-looking kids with solid black eyes that might be ET-human hybrids Bigfoot the werewolf-like Dogmen jellyfish-style aliens that soar around the skies of our world the Shadow People: dangerous humanoids that terrorize people legendary Nephilim space-vampires: insect-like aliens that resemble a giant praying mantis and many, many more! The Alien Book investigates the full range of sentient, alien life forms. Some are benign and others downright deadly. Some are small, like a germ or virus that has NASA, creating guidelines to deal with an outbreak of an extraterrestrial germ. Some are big like a giant praying mantis or the biblical Goliath. They all lurk on Earth and in this chilling book! With more than 120 photos and graphics, this tome is richly illustrated. Its helpful bibliography and extensive index add to its usefulness.
