In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.

Ancient cultures around the world spoke of a vast cycle of time with alternating dark and golden ages; Plato called it the Great Year. Most of us were taught in school that the dark ages were real but the golden age was just a universal myth. But new scientific evidence suggest this cycle of high and low ages may have some basis in fact. Now that the astronomical community has discovered that something massive is tugging on our solar system the stage is set for discovering the motion that moves us from high ages of enlightenment to low ages of darkness.

Why did Elon Musk feel compelled to send a red Tesla into space? What accounts for the multiple rocket-themed playgrounds constructed after the Russians launched Sputnik? Gorman - affectionately known as "Dr Space Junk" - takes listeners on a journey through the solar system and beyond, deploying space artifacts, historical explorations, and even the occasional cocktail recipe in search of the ways that we make space meaningful. Engaging and erudite, Gorman recounts her background as a (nonspace) archaeologist and how she became interested in space artifacts.

Written by Oxford astrophysicist Dr Becky Smethurst and composed of 10 captivating, simple essays, it guides you swiftly through the galaxies, explaining the mysteries of black holes, dark matter and what existed before the big bang, presenting the evidence as to whether we really are alone, illuminating what we still don't know and much more besides. If you have big questions about space, this book will provide you with the answers in an engaging and succinct way.

Elon Musk founded SpaceX with the mission of making humans a multiplanetary species. In the coming years, SpaceX will launch a crew of 24 people through space and onto Mars, in a new kind of rocket called Starship. Over 80 million miles away, Mars is both desolate, and at the same time, full of limitless potential. Mars holds limitless possibilities. Since the ideal alignment for Earth and Mars only happens once every two years, there is only a small window to get everything right.

Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones - from the tiniest particles to the nature of space-time itself - black holes might be the key to a deeper understanding of the cosmos.

There seems to be evidence to suggest that our world and everything in it are only ghostly images: projections from a level of reality so beyond our own that the real reality is literally beyond both space and time. The main architect of this astonishing idea is one of the world’s most eminent thinkers - physicist David Bohm, a protégé of Einstein’s. In this executive summary, Chuck gives a current perspective on some of the areas that define our reality.

These 12 half-hour lectures are about what Einstein got wrong. He may have kindled a scientific revolution with his famous theory of relativity and his proof that atoms and light quanta exist, but he balked at accepting the most startling implications of these theories - such as the existence of black holes, the big bang, gravity waves, and mind-bendingly strange phenomena in the quantum realm. This course by research physicist Dan Hooper of the University of Chicago assumes no background in science and uses very little math.

The next frontier in space exploration is Mars, the Red Planet - and human habitation of Mars isn't much farther off. In October 2015, NASA declared Mars "an achievable goal"; that same season, Ridley Scott and Matt Damon's The Martian drew crowds into theaters, grossing over $200 million. Now the National Geographic Channel fast forwards years ahead with Mars, a six-part series documenting and dramatizing the next 25 years as humans land on and learn to live on Mars.

The ordinary atoms that make up the known universe - from our bodies and the air we breathe to the planets and stars - constitute only 5 percent of all matter and energy in the cosmos. The rest is known as dark matter and dark energy, because their precise identities are unknown. The Cosmic Cocktail is the inside story of the epic quest to solve one of the most compelling enigmas of modern science - what is the universe made of? - told by one of today’s foremost pioneers in the study of dark matter.

Is Earth merely an insignificant speck in a vast and meaningless universe? On the contrary: The Privileged Planet shows that this cherished assumption of materialism is dead wrong. In this provocative book, Guillermo Gonzalez and Jay W. Richards present a staggering array of evidence that exposes the hollowness of this modern dogma.

Take a fact-based journey through the cosmos. Tune in to hear weekly discussions on astronomical topics ranging from planets to cosmology. Hosted by Fraser Cain (Universe Today) and Dr. Pamela L. Gay (Planetary Science Institute), this show brings the questions of an avid astronomy lover direct to an astronomer. Together Fraser and Pamela explore what is known and being discovered about the universe around us. Astronomy Cast is supported thru patreon.com/AstronomyCast.

Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes.

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

Explore the secrets of the universe with selections from the works of three of the greatest scientific minds of our lifetime. Widely regarded as the most brilliant theoretical physicist since Einstein, Stephen W. Hawking has delved into today's most important scientific ideas about the cosmos, expanded upon the rich history of scientific thought, and reveled in the complexities of the universe in which we live.

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course - a procedure depicted in several Hollywood movies.

In this unique celebration of the moon, lunar expert and space scientist Dr Maggie Aderin Pocock takes listeners on a journey through the moon’s past, present and future. She uncovers the way the moon has captured our imaginations, contemplates how it was formed, and uncovers why we need the moon to protect our fragile earth. Drawing on the latest scientific research, she then looks forward to what might be to come - will we return to the moon, or will it become a launch pad to go into the great unknown?

Are you curious about UFOs and aliens? Have you been wondering why UFOs come and where they come from? Do you believe that time travel is possible? Could aliens simply be humans from the future, visiting their old home, using UFO as a time machine? And why do I think so? Well, get the book, listen on, and find out more....

Our universe has been growing for nearly 14 billion years. But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its existence. In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes.
