Earth Space Science

When Darius’ newly founded colony on Umbria Prime is attacked, he fights off the raiders and finds clues that humanity’s old foes–the Iglax–are to blame. Once again, he’s got to return to the galaxy at large to upgrade his ships, advance his skills, and spread humanity further among the stars.

Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers - from the Sputnik and Explorer satellites launched in the late 1950's to the thrilling interstellar Voyager missions of the '70's - that yielded some of the most celebrated successes and spectacular failures of the space age. Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond.

Earth, from space, looks like a shimmering gem suspended in an inky, infinite expanse. But this serene image masks the magnificent and volatile interior forces that make life possible for millions of species on the surface. The placid appearances of our neighboring planets similarly belie their powers—and science fiction-worthy features, like diamond rain.

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.

Five years ago, we won our first galactic war. We defeated the scum, a race of alien centipedes. But the marauders are stronger, smarter, and crueler by far. And they will show us no mercy. Marco Emery, hero of the last war, struggles today as a civilian. Shell shock cripples him. Nightmares haunt him. Yet now he must become a soldier again. Now his old platoon must reunite. Together, they must defeat the greatest threat Earth has ever known. Or humanity will fall.

They call themselves the next step in human evolution. But we call them "scummers." They are hybrids. Humans with alien DNA. They attacked us. They butchered us. Now we fight back. Under the leadership of Einav Ben-Ari, our brave soldiers fly to the scummer planet. To war. But we face a terrifying foe. The scummers are stronger than us. Faster. Fiercer. And their queen is none other than Lailani de la Rosa . . . Ben-Ari’s oldest and best friend.

Aliens ripped a hole above Earth, arriving with a massive space station. I sorta figured we'd be enslaved to fight in their wars or exterminated for our resources. Nope. The hip-high Iglax were merchants with ugly squished faces and thick blue fur. While they weren't much to look at, they sure did have some wonderous technology.

Zetetic Astronomy is the magnum opus of Samuel Rowbotham (1816-1884), a self-taught polymath, debater, faith healer, and early advocate of Utopian socialism. Drawing from a wide variety of contemporary sources, Christian scripture, and his own investigative and experimental skills, Rowbotham advocated tirelessly for his thesis that the true shape of the Earth was a plane, refuting all suggestions of rotundity. His arguments continue to captivate, persuade, and entertain up to the present day.

Beliefs about the shape of the earth have varied over the millennia, but the Ancient Greeks were able to observe that our planet is round and even Eratosthenes attempted to measure its size. It was not until explorers had fully charted the globe that most people were really able to comprehend its spherical shape.

Welcome to the alien zoo. In here, you’ll meet a variety of life from across the universe. Floating balloons of flesh from a gas giant’s storm. Sentient moss that controls golems of stone. Towering arachnids whose webs can entangle starships. And in one enclosure… humans. Us. This zoo, you see, is run by powerful aliens. To the zookeepers, we are mere animals. Marco, Addy, and Einav are soldiers. Together, they fought many wars. And won them all. But now they’re trapped in a cage. Disarmed. Demeaned. Animals on display.

Earth burns. After generations in exile, we returned to our long-lost planet. Scarred. Haunted. Survivors. We - the last humans - are finally home. But our enemies still crave our blood. Seven alien species unite. Seven fleets bombard our planet. Seven armies invade our beautiful world. They have one goal: To kill us all. We refuse to lose Earth again. We will resist. We will fight for every hill, every valley, every stone, and blade of grass. We will defend our planet. At any cost. Together, we will raise our voices. We will sing the song of Earth. We will tell the enemy: Earth is ours!

Former NASA astronaut Terry Virts offers an insider's guide to astronauting—a behind-the-scenes look at the training, the basic rules, lessons, and procedures of space travel, including how to deal with a dead body in space, what it’s like to film an IMAX movie in orbit, what exactly to do when nature calls, and much more, in 51 brief chapters.

Hackett, in his trusty ship the Perseus, is not just a space traveller—beginning his travels with an expedition to Neptune and back—but, thanks to the time-dilation effect, a time traveller as well. His new mission will take him to Andromeda, to get a close-up look at the constellation which will eventually crash into the Milky Way, and give humanity a heads-up about the challenges which are coming. A mission which will take him five million years to complete. Not only is Hackett exploring unknown space, but he will return to a vastly different time.

Darius has enjoyed a nice break from an action packed integration into the GGA. With Earth in limbo, and a lost colony likely in need of help, he knows his vacation is on borrowed time. He owes the Merchant Marines, Pavia, and humanity itself to do more, to be more. So when life is turned upside down again, he ventures back into the stars, helping those he can, when he can. The adventure is intense, his family bonds are tight, and the dangers ever-present.

It's all-out war. Our cities fall. Millions die. The scum, these cruel aliens from deep space, are determined to kill us all. So we must kill them. Humanity musters its greatest fleet. Thousands of starships rally. Millions of soldiers deploy. For Earth to stand a chance, we must invade the aliens' home world. We must destroy their planet. Before they destroy ours. Earth's fleet flies through space. We fly toward millions of enemy ships. We fly to almost certain death.

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 realization that the dinosaurs were 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.

In the fourth book of the Extinction Wars series, Abaddon commands a Karg-Jelk Super Fleet bent on annihilating humanity. He's the galaxy's most ruthless strategist wielding superior technology. That includes the perfect raid-ships, able to teleport anywhere at will. Humanity has Commander Creed, and he has his Assault Troopers. He's going to take the fight to the enemy. He's buying time, learning secrets and setting up for the greatest space battle in the Orion Arm.

Flat Earth has long been denigrated, derided, and disparaged as being the most crackpot of all conspiracy theories, marginalized, mocked, and ridiculed for centuries as being an ignorant ancient unscientific worldview, but the facts of the matter are far from what you have been told. When thoroughly examined and diligently researched with an open-mind, any skeptical critical-thinker will find it is actually the tilting, wobbling, spinning space-ball Earth promoted by NASA and taught in schools that is truly ridiculous and unscientific.

When Nicole Stott first saw Earth from space, she realized how interconnected we are and knew she had to help protect our planetary home. In Back to Earth, Stott imparts essential lessons in problem-solving, survival, and crisis response that each of us can practice to make change. She knows we can overcome differences to address global issues, because she saw this every day on the International Space Station. Stott shares stories from her spaceflight and insights from scientists, activists, and changemakers working to solve our greatest environmental challenges.
