The Big Bang is all but dead, and we do not yet know what will replace it. Our universe's "beginning" is at an end. What does this have to do with us here on Earth? Our lives are about to be dramatically shaken again - as altered as they were with the invention of the clock, the steam engine, the railroad, the radio and the Internet.

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. It’s one of our culture’s favorite conversations, and yet, the idea of extraterrestrial intelligence has been largely banished to the realm of fantasy and conspiracy. Now, for the first time, the full story of our national obsession with UFOs is told.

A revolution is underway. For the first time in human history, we are at the cusp of experiencing contact with nonhuman life-forms of all kinds due to technological innovations and research into the experiences of people at the forefront of this development. In Encounters, author D.W. Pasulka takes listeners to the forefront of this revolution, sharing the work of experts across a spectrum of fields who are working to connect humanity with unknown life-forms.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work.

Since Copernicus, humanity has increasingly seen itself as adrift, an insignificant speck within a large, cold universe. Brazilian physicist, astronomer, and winner of the 2019 Templeton Prize Marcelo Gleiser argues that we’re using the wrong paradigm to relate to the universe and our position in it. In this deeply researched and beautifully rendered book, he calls for us to embrace a new life-centric perspective, one which recognizes just how rare and precious life is and why it should be our mission to preserve and nurture it.

In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard’s Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth.

Geddy Lee is one of rock and roll's most respected bassists. For nearly five decades, his playing and work as co-writer, vocalist and keyboardist has been an essential part of the success story of Canadian progressive rock trio Rush.

More than half of American adults and more than 75 percent of young Americans believe in intelligent extraterrestrial life. This level of belief rivals that of belief in God. American Cosmic examines the mechanisms at work behind the thriving belief system in extraterrestrial life, a system that is changing and even supplanting traditional religions.

Skinwalkers at the Pentagon unmasks the massive scope of the Pentagon’s landmark UFO study that ran from the Defense Intelligence Agency in Washington, DC. The Advanced Aerospace Weapon System Applications Program or AAWSAP investigated the “Tic Tac” and other “nuts and bolts” UFO events, analyzed intrusions of UFOs onto US military bases, as well as probed the plethora of bizarre phenomena that government investigators encountered on Skinwalker Ranch.

Inspired by her research for the hit podcast Ultra, Rachel Maddow charts the rise of a wild American strain of authoritarianism that has been alive on the far-right edge of our politics for the better part of a century. Before and even after our troops had begun fighting abroad in World War II, a clandestine network flooded the country with disinformation aimed at sapping the strength of the U.S. war effort and persuading Americans that our natural alliance was with the Axis, not against it.

Ever since a childhood visit to Washington, DC, Cassidy Hutchinson aspired to serve her country in government. Raised in a working-class family with a military background, she was the first in her immediate family to graduate from college. Despite having no ties to Washington, Hutchinson landed a vital position at the center of the Trump White House.

Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change.

Three of the most important words in science are I don't know. Not knowing implies a universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last 500 years, yet many fundamental mysteries of existence persist: How did our universe begin? How big is the universe? Is time travel possible? What’s at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it?

By the star physicist and author of multiple #1 Sunday Times bestsellers, a major and definitive narrative work on black holes and how they can help us understand the universe.

For centuries, people have speculated about the possibility of planets orbiting distant stars, but only since the 1990s has technology allowed astronomers to detect them. At this point, more than five thousand such exoplanets have been identified, with the pace of discovery accelerating after the launch of NASA’s Transiting Exoplanet Satellite Survey and the Webb Space Telescope. In The Little Book of Exoplanets, Princeton astrophysicist Joshua Winn offers a brief and engaging introduction to the search for exoplanets and the cutting-edge science behind recent findings.

How would Saturn’s rings look from a spaceship sailing just above them? If you were falling into a black hole, what’s the last thing you’d see before your spaghettification? What would it be like to visit the faraway places we currently experience only through high-powered telescopes and robotic emissaries? Faster-than-light travel may never be invented, but we can still take the scenic route through the universe with renowned astronomer and science communicator Philip Plait.

Earth is not well. The promise of starting life anew somewhere far, far away—no climate change, no war, no Twitter—beckons, and settling the stars finally seems within our grasp. Or is it? Critically acclaimed, bestselling authors Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of research, they aren’t so sure it’s a good idea.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

What is life?

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.

The violent birth of the universe was only the first bang of a very bumpy ride. This unfathomably cacophonous beginning has spawned blasts, implosions, cosmic cannibalism, collisions, and countless other fleeting energetic events punctuating the cosmos. Although often brief, these transient phenomena pack a powerful punch. Astronomer and science writer C. Renee James introduces us to her colleagues around the world, who are using pioneering research techniques to explore everything from the very first explosions in the universe to the dark energy that could destroy it all.

Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark.

Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet?

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?

With a foreword from Professor Brian Cox and access to all the latest NASA mission information, Andrew Cohen takes listeners on a voyage of discovery via the probes and telescopes exploring the outer reaches of our galaxy, revealing how it was formed and how it will inevitably be destroyed by the enigmatic black hole at its heart. And beyond our galaxy, the expanding universe, which holds clues to the biggest mystery of all - how did it all begin?

So you’ve fallen in love with space and now you want to see it for yourself, huh? You want to witness the birth of a star, or visit the black hole at the center of our galaxy? You want to know if there are aliens out there, or how to travel through a wormhole? You want the wonders of the universe revealed before your very eyes? Well stop, because all that will probably kill you.

Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets.
