Earth Space Science

The Trellixian Empire was constantly expanding, seeking new worlds for its ever-increasing population. If worlds were discovered with existing sentient populations, they were cleansed to make room for colonization. Hundreds of budding civilizations had been eliminated by Trellixian battle fleets. On Earth, years in the past, a scout ship fleeing from the Trellixians crashed. Scientists investigating the wreckage discovered what the Trellixians had done to the world the scout ship escaped from. They also discovered it was only a matter of time before the Trellixians reached Earth.

Humankind has escaped a dying Earth and set out to find a new home among the stars aboard an immense generation ship affectionately named the Ark. Bryan Benson is the Ark's greatest living sports hero, enjoying retirement working as a detective in Avalon, his home module. The hours are good, the work is easy, and the perks can't be beat. But when a crew member goes missing, Bryan is thrust into the center of an ever-expanding web of deception, secrets, and violence.

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.

We've pinpointed the destination, refined the technology, designed the habitat. Are we forgetting something? A timely reminder that it's not just rocket science, this book explores the all-too-human issues raised by the prospect of settling in outer space. Accordingly, her work highlights the complex ethical challenges that accompany any other-worldly venture—questions about the environment, labor rights, and medical ethics, among others.

Captain Clayton Cross and his crew encountered the Kyra, an advanced race of avian carnivores. They fled this first encounter, but the Kyra beat them back to Earth by almost a century. Earth lost the war in just a few weeks. Our cities burned, and billions died. After we surrendered, the Kyra helped us to rebuild, but on their terms, confining us to city centers and building high walls to keep us in.

Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky.

When Kell and his team return to Earth many years after their departure, they find that their world has changed almost beyond recognition. Not only has a second wave of greenhouse flooding caused sea levels to rise, but society has been changed by the consequences of the climate shift. Few people want to face Jordan Kell's news. He must convince Earth's new rulers that the human race is in danger of extinction unless it acts to forestall the death wave coming from the galaxy's heart.

The Singularity has come. The machines have risen. Our robots, once loyal servants, now slaughter us. Our cars, planes, and starships have become machines of death. Cyborgs roam the land, deforming humans, growing their twisted army. Is a heartless, mechanized hell our future? A faint hope shines. Heroes still fight. Famous names. Einav. Marco. Addy. Lailani. The heroes of the Alien Wars. Names etched in our history, in our hearts. Four friends. Four humans...against an army of metal.

The astronauts headed to the moon in December 1972 thought they knew what to expect. They would soon be exploring the moon’s surface in a lunar rover, traveling farther than anyone before them. They would be collecting soil and rock samples for study back on Earth and could expect to learn about the moon’s physical makeup and age.

If a black hole is not a hole, then what is it? Find out what black holes are, what causes them, and how scientists first discovered them. Learn how astronomers find black holes, get to know our nearest black-hole neighbor, and take a journey that will literally s-t-r-e-t-c-h the mind.

Meet Moon! She's more than just a rock - she’s Earth’s rock, her best friend she can always count on. Moon never turns her back on her friend (Literally: She's always facing Earth with the same side!). These two will stick together forever. With characteristic humor and charm, Stacy McAnulty channels the voice of Moon in this next celestial "autobiography" in the Our Universe series.

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.

This audiobook begins with the question "Who am I?" and immediately sets off in an astonishingly original direction. Why didn't anyone before Harding think of responding to this question like this? It's so obvious, once you see it. Harding presents a new vision of our place in the universe that uses the scientific method of looking to see what is true. It turns out that the truth about ourselves is not only true but also very good, and breathtakingly beautiful. We live in a sacred, many-layered, living universe - or rather it lives in us.

Kayan has emerged from the Hoyon citadel repaired and refreshed, though she’s a bit cagey. Why would she share what kind of upgrades the healing process bestowed upon her? Noah Gantz is just glad to be back in the action, seeking Seer secrets, a way to save two galaxies, and finding Kilis Dane Ryger before Celia and Ryg destroy Kayan to get their answers. When Kayan’s crew learns Dane may have genetically modified Azok warships, they pursue the clues back to the Milky Way and Earth.

When on land, rivers, lakes, and oceans appear flat. With the aid of satellites, these bodies of water appear to have many designs! Explore the art of nature and how satellites detect the temperature of the many bodies of water around the globe.

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.

Earth burns. We call them the scum. They came from deep space. Creatures of claws and endless malice, they ravage the world. As the war flares, as cities crumble, Private Marco Emery and his platoon blast into space. They won one battle on Earth. Their next battle must be fought in the darkness. The scum will not rest until the last human is dead. Marco and his friends must defeat them. They must win. Or Earth will fall.

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.

Seven billion years from now, long after the Sun has died and human life itself has become extinct, alien beings reincarnate humanity from our fossilized DNA drifting as debris in the void of deep space. We are reborn to serve as bait in a battle to the death between the Rimstalker, humankind's reanimator, and the zotl, horrific creatures who feed vampire-like on the suffering of intelligent lifeforms.
