In Journey Through The Solar System, you can join the experience of a lifetime without leaving your home. Get ready for an unforgettable space holiday! You're about to launch on a voyage beyond your wildest dreams, touring the marvels of our Solar System (the sun, planets, comets, and asteroids) and the mysteries of the cosmos.

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.

Are you up for a trip through the ultimate neighborhood? Join astrophysicist Hugh Ross for an insider’s look at our cosmic neighborhood, where you’ll see everything from the largest-scale structure of the universe to Earth’s innermost layers. In Designed to the Core, Ross explains how the most sophisticated scientific instruments reveal exquisite “interior designs” throughout the universe that are ideally suited for human habitation here on Earth right now.

The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

The Sun, Moon, and stars are crucial to your daily existence. The perfect regularity of the heavens is the only guaranteed part of life and inspires deep religious and philosophical ideas, while unexpected events such as eclipses and comets incite fear. Experience this ancient outlook with noted astrophysicist and historian of astronomy Professor Bradley Schaefer of Louisiana State University. An award-winning teacher, Dr. Schaefer takes you around the world, exploring the close relationship that people thousands of years ago had with the sky.

In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

Written for the general lay listener, The Living Universe explores how the latest scientific discoveries are rewriting what we thought we knew about space, planets, and the origins of life. We now know that the universe is filled with planets, not just around other stars but also traveling in the space between them, and that many of these carry life with them. Some of these wandering planets have almost certainly been captured by the Sun's gravity, changing not just the arrangement of planets in the Solar System, but also the development of life on our Earth.

Mars has been a source of fascination and speculation ever since the ancient Egyptians observed its blood-red hue and named it for their god of war and plague. But it wasn't until the 19th century when "canals" were observed on the surface of the Red Planet, suggesting the presence of water, that scientists, novelists, filmmakers, and entrepreneurs became obsessed with the question of whether there's life on Mars. The Big Book of Mars is the most comprehensive look at our relationship with Mars - yesterday, today, and tomorrow.

Journey into the most mind-boggling mysteries of the cosmosUncover the blinding power of quasars, brighter than a trillion suns, that outshine entire galaxies. Explore the coldest reaches of the universe, where temperatures plummet to near absolute zero, defying the very essence of life. And venture into the tantalizing question of life beyond Earth—could it thrive on distant exoplanets, under alien suns, or in oceans hidden beneath icy worlds?Each episode takes you deeper into the unknown, unraveling secrets that challenge the boundaries of science and ignite the imagination. Are you ready ...

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.

Ragnarok. Armageddon. Doomsday. Since the dawn of time, man has wondered how the world would end. In The Last Three Minutes, Paul Davies reveals the latest theories. Voiced in clear language that makes the cutting-edge science of quarks, neutrinos, wormholes, and metaverses accessible to the layman, The Last Three Minutes treats listeners to a wide range of conjectures about the ultimate fate of the universe.

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.

Les Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges that we need to overcome in order to realize tomorrow's possibilities.

Until I began to build and launch rockets, I didn't know my hometown was at war with itself over its children, and that my parents were locked in a kind of bloodless combat over how my brother and I would live our lives....And I didn't know that the enthalpy decrease in a converging passage...

On July 14, 2015, something amazing happened. More than three billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long-mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.

Scientists tell us that ninety-six percent of the universe is unexplained dark matter and dark energy. Also, they admit that no unifying “theory of everything” exists in physics. This shaky foundation is the basis of modern thinking about the cosmos and Earth’s place in it. Something big seems to be missing. Thus, we’re left with no choice but to question the “consensus” cosmological model. Are we really flying through space on a spinning ball within an expanding universe, while free-falling around the Sun—all as a consequence of a “Big Bang” that supposedly occurred 13.8 billion years ago?

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.
