Earth Space Science

In this intriguing recording, Professor Emeritus Timothy Ferris—one of the world's most respected science writers—explores man's search for life elsewhere in the universe. Ferris combines new discoveries about the origins of life as we know it on Earth with recent revelations about the sun's planets and their moons. Ferris explains why many scientists are convinced that life is abundant throughout the cosmos, and he considers how one day radio telescopes may be used to connect us to an intergalactic Internet and link us to alien civilizations in the far reaches of the universe.

Four centuries have passed since the end of the alien invasion that almost destroyed humanity. The surviving races, human and alien, now live in peace as allies. But when a terrifying new enemy cuts a path of destruction through the Alliance, there seems little hope of resistance. The situation is desperate, and desperate measures are required. With reluctance, they agree to resurrect a hero from the past, Colonel Mitch Taylor.

The Alliance of the Human, Krys, Aranui, and Cholan peoples lies in tatters after they turn on one another when a new threat emerges. The enemy is the Morohta, led by their fearsome queen, Bolormaa. A hard-fought battle buys the Alliance valuable time until the Morohta force the submission of the Cholan Empire. The Cholans then point their guns at the Alliance and demand their surrender.

The people of planet Earth have suffered the tides of war for six long years, but it's not their war. Earth is the battleground for the thousand-year conflict between the invading Hahnshin and the Godan warriors of the Galactic Confederation. Mira Donazetto's only concern is for her family's survival, so when she's offered work as a translator for the Godan, she jumps at the chance and right into the arms of the new First Commander, Roark.

A signal has been picked up from Earth. The planet was supposed to be uninhabitable. But it seems there are survivors down there - with supplies, shelter, and running water. Perhaps there could be a future for humanity on Earth after all. Riley Hale will find out soon enough. She's stuck on a spaceship with the group of terrorists that is planning to brave the planet's atmosphere and crash-land on the surface. But when the reentry goes wrong, Riley ends up hundreds of miles from her companions, Prakesh and Carver.

Los Angeles, 1930s: Everyone knows that rockets are just toys, the stuff of cranks and pulp magazines. Nevertheless, an earnest engineering student named Frank Malina sets out to prove the doubters wrong. With the help of his friend Jack Parsons, a grandiose and occult-obsessed explosives enthusiast, Malina embarks on a journey that takes him from junk yards and desert lots to the heights of the military-industrial complex.

The year is 2512, and war rages throughout the Alliance. Warriors are needed, those who have the will, the skills, and the strength to fight this new threat. The cry goes out for battle-hardened soldiers. Like those who fought in the brutal war that nearly destroyed Earth almost 400 years ago. A resurrection program has begun to bring back those few men who had been preserved, and CJ is next. But CJ is no ordinary soldier.

Dr. Rebecca Carter stood at the front of a crowded auditorium, the bright lights shining down on her as she addressed the audience. She spoke with conviction, her voice filled with intelligence and determination. "But we can't afford to ignore the evidence any longer," she argued, her eyes flashing with intensity. "These solar flares are unlike anything we've ever seen before. They're increasing in frequency and intensity, and if we don't act soon, Earth will be destroyed."

For years, Earth's heroes fought united. They faced alien armies in war. They defended Earth as friends. As a fellowship. Now they break apart. Lailani de la Rosa, heroine of the Alien Wars, aligns herself with a new enemy. She rises to lead the scummers, a breed of human-alien hybrids.

We’re finally ready to take the war back to the Hedalt. But they’re coming for us first, and in force. Yet the Hedalt Armada, led by High Provost Kagan, is far from our only problem. I am Captain Taylor Ray. On the eve of war, a new commander threatens to derail everything that Commander Sarah Sonner and I have fought for. While Sonner becomes locked in an internal power struggle, my unique crew and I must go rogue and take out the source of the Hedalt’s supremacy - the mysterious Nexus.

In order to ensure he can feed his growing family and the family of his friends, Marcus must build the first blooddoll factory on Earth. Unfortunately, the living planet poses challenges. He's certain Earthlings would vehemently object to his plan to create humans for food, so he plans to hide his true intentions by opening a homeless shelter.

Shadow, Marcus, and their friends made it to Earth, but they still have a food problem. Earthling blood isn't palatable, and they only have a two-month supply of bloodbags. Marcus must find a way to distill Earthling blood and create a long-term food supply that will feed them and their growing vampire families while not alerting the humans to their presence.

With the return of 8-3-9-6, Kevin has to defeat the AI's master to free himself from their collective grasp. But to succeed, he first has to go against Myrianna, the tech sorceress who trained him. To make things worse, Kevin must achieve this task on his own since his friends have been imprisoned on Arcadia Prime. Meanwhile, the new Kregan Emperor, Xonax, is on his way to Earth with an entire armada determined to obliterate the human race. The clock is ticking, and the stakes are high. Everyone Kevin loves, as well as his entire planet, is in jeopardy. And there's no margin for error.

A desperate battle for Richmond is about to begin, but Colonel Taylor knows that the war cannot be won if the Alliance continues its current path. When the genius Milo Rivers offers hope, both Taylor and Major Sommers are dispatched to retrieve information and technology which could turn the war around. Yet, Taylor’s Marines are about to descend into a deadly trap, and they must fight not just for the future of Earth, but survive to see another day.

Earth is soon consumed by the invading alien armies as they land in their millions, and Mitch Taylor is the enemies' first target, knowing the danger he presents. Can Taylor escape his captors and rally those on Earth to fight back before it is too late, or will he fall alongside the rest of Earth’s defenders in a desperate last stand?

Opportunities there are few and far between...that is, unless you're willing to put on a uniform. For ace-pilot Deborah Allen Riker (aka “Admiral Dare”), life had never been easy. She's defended Earth against countless enemies, both alien and human alike. Now she's retired. Committed to a life of solitude and studying the aliens she spent a lifetime fighting...until she finds herself dragged into a new conflict. A conflict she never saw coming.

Living in the Fellowship meant fighting one space battle after another. Every civilization was aggressive, hostile, and impossible to live with in peace. A Welken task force stumbles upon a massive Myot ship building complex and every Welken warship is destroyed in the ensuing battle before they can warn the home world of the Myot's location. One escape pod manages to escape the battle and the Myot know it must be prevented from making it back to Welken territory.

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces listeners to the science of near-Earth objects - its history, applications, and ongoing quest to find near-Earth objects before they find us.

In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars but Titan - a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will be able to fly like birds in the minimal gravitational field - offers the most realistic and thrilling prospect of life without support from Earth.
