Speaking with key leaders of the latest space programs and innovations, Rod Pyle shares the excitement and promise of this new era of exploration and economic development. From NASA and the Russian space agency Roscosmos, to emerging leaders in the private sector, Space 2.0 examines the new partnerships that are revolutionizing spaceflight and changing the way we reach for the stars.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

On October 4, 1957, a time of Cold War paranoia, the Soviet Union secretly launched the Earth's first artificial moon. No bigger than a basketball, the tiny satellite was powered by a car battery. Yet, for all its simplicity, Sputnik stunned the world.

In 1957 the Soviet Union sent Sputnik, the first man-made satellite, into space. America took up the challenge to explore the next frontier. A dozen years, and 25 billion dollars later, the mission of Apollo 11 would yield man's finest hour. For that was the first time man's foot left prints on another heavenly body. And that was only the beginning. Apollo 11 is the incredible story of how a nation forged the technology during the turbulent 1960s to slip humanity from the bonds of its native planet. This inside look remembers those who made the great enterprise succeed.

Science fiction has imagined some pretty wild ideas about how the universe could work - from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared to the mind-bending science now coming out of physics and astronomy, and in this audiobook, we look at the strange and fascinating discoveries shaping (and reshaping) the field today.

How did life begin on Earth? Does it exist elsewhere? What would those life forms be like? These fundamental questions about the nature of life and our own cosmic significance are endlessly fascinating. In this book, we present several theories on the origin of life, some of its extreme and surprising forms, and the ongoing search for signs - or sentience - on distant worlds.

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?

An ideal introduction for beginner and seasoned stargazers alike from the astronomers of the Royal Observatory Greenwich. Astronomy expert Tom Kerss offers complete advice from the ground up, introducing the world of telescopes, planets, stars, dark skies and celestial maps, explaining the best...

Was it fun to do a space walk? How squashed were you in the capsule on the way back? What were your feelings as you looked down on Earth for the first time? Were you ever scared? Where to next -- the Moon, Mars, or beyond? Based on his historic mission to the International Space Station, Ask an...

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

From the best-selling author of The Emperor’s New Mind and The Road to Reality, a groundbreaking book that provides new views on three of cosmology’s most profound questions: What, if anything, came before the Big Bang? What is the source of order in our universe? What is its ultimate future?...

This book is the boundary between science and philosophy dissolves into a haunting exploration of existence itself. Beginning with the mysterious precision of the universe’s physical constants and ending at the silent edge of knowledge, this book traces the anthropic principle not as an answer, but as a profound and unsettling question. From the delicate balance that permits life to the strange recursion of a cosmos observed by minds it created, each chapter draws closer to a truth that cannot be fully named.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed the place, scale and geometry of earth–the third planet from the Sun, formed 4.5 billion years ago–in our solar system.

A Mysterious Universe introduces the fundamental laws of quantum mechanics, theory of relativity, and cosmology to a novice in simple language. This concise book deals with deep issues related to the mysteries of modern physics.

When ancient people first sought to explain the mysteries of their own lives, they looked to the heavens. There, they saw a perfect reflection linking them directly with an omniscient universe. The study of the stars and the study of the psyche comprised a single science—astrology—which led...

Originally published in 1926, The Russell Genero-Radiative Concept is a concise and provocative exposition of Walter Russell’s cyclic theory of continuous motion. In this rare work, Russell outlines a universe governed not by linear mechanics, but by rhythmic balance—where all matter, energy, and motion arise from the interplay of generative and radiative forces.

When Ed White, clad in his gleaming space suit with a large American flag on his left shoulder, eased himself outside his Gemini spacecraft in 1965, Americans had a new space hero. They also learned a new acronym: EVA, short for extravehicular activity, more commonly known as "spacewalking." Though few understood the tremendous risks White was taking in his twenty-two-minute space walk, Americans watched with immense pride and patriotism as White, tethered to Gemini 4, propelled himself around the spacecraft with a pressurized oxygen-fueled zip gun.

In this episode, we dive into the complex relationship between astrology and mental health — how it can offer comfort, self-reflection, and meaning, but also create anxiety, fear, and emotional dependence when taken too far. From confirmation bias to identity fixation, we unpack why astrology feels so powerful and how to use it without losing your personal agency. It’s a thoughtful look at where spirituality, psychology, and self-awareness meet.
