Earth Space Science

Given the chance to at last snag the hot office assistant he's been after, Jake sets into motion a snowball of events that lead him to strange new worlds-some not of this realm-and to truths not meant to be discovered. With it, humanity dares to challenge the ancients. Now, Earth's Legions must fight for all.

It’s more than just a career - it’s a sacred calling…but it comes with a very short life expectancy. Lord Kreon, Warden of the First Circle, has a problem: he’s been forced to kill another apprentice, and he’s rapidly running out of candidates. In fact, there is precisely one left….

Branded a hero after the victory on Atlas, Jake Adlar is honored with a personal introduction to the Legion's Legate. Easy. What could possibly go wrong? Then he'd be free to confront the deranged, body-snatching Centurion in league with the Synths and save some lives. Meanwhile, the sleeks, who showed up as Earth's saviors only to make humanity their slaves, have enlisted the Legion's services in a mercenary gig.

Tragedy and triumph war for supremacy, but the victory will be short-lived. Because the terrifying race known as the Siszar—once humanity’s greatest foe—have requested our aid. Not even they are immune to the devastation caused by the Black Ships. Their homeworld has been destroyed. Kreon, Tristan and Kyra must fight their way deep into alien territory, to forge an alliance with a creature half as old as time. Only then can they have any hope of defeating the Black Ships. But not everyone wants them to succeed.

The rebellion has been utterly crushed. Lord Anakreon and his crew are fleeing for their lives. Now, as the handful of survivors are hunted throughout the Empire, he conceives of one last, desperate plan. Winning is impossible. Survival is unlikely. But he will have his revenge. For his apprentice, Tristan, time is running out. His entire life has been leading up to this point: he must step through the ancient alien Portal that killed his father. What lies beyond it, no one knows, because no one has ever survived the journey. But he has to try.

One world at a time, the entities known as Black Ships are wiping out all sentient life. There is no way to stop them. No way to find them, even...because no one has ever survived an encounter. And yet, the hologram of a long-dead Warden points towards a glimmer of hope; an ancient Oracle hidden deep in enemy territory. Could this be the key to unravelling the mystery?

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.

On board an X101 stealth aircraft, Lauren, Jack, and Mike arrive at the secret location of Sky Dreamer Corp - a place equipped with technology and resources far more advanced than anything they could have ever imagined.

Can Lauren successfully draw upon all her skills to fight off both threats from the Overseers and from beyond our world? Earth Howl is the sequel to Earth Shout, and is part of the Multiverse Chronicles, an epic series of interlinked stories that includes the Fractured Light trilogy, following humanity’s struggle to survive across parallel universes.

In a desperate battle, Earth has temporarily freed itself from the clutches of the deadly Trellixian Empire. Billions are dead and it's only a matter of time before the enemy return. Seeking aid against the Trellixians, two exploration ships are sent out to search the galaxy for allies. If they fail, then the human race is doomed.

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.

Inspired by insights gained in spaceflight, a NASA astronaut offers key lessons to empower Earthbound readers to fight climate change 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...

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

Lord Anakreon, Warden of the First Circle, has lost a weapon. Not just any weapon; the Planet Forge is an ancient alien artefact with the power to create worlds…or to end them.

The Earth had four fleets to fight the invading enemy. The first fleet valiantly protected earth, but it wasn’t enough. Three fleets would arrive soon and end the threat...but they never came through the wormhole. One ship escaped the massacre, fleeing deep into space while the rest of Earth’s defenses were destroyed. Only the barrier around the planet keeps the enemy from finishing what they started.

In the year 2357, the galaxy teeters on the brink of chaos as the United Terran Federation battles a powerful and mysterious insectoid race. Eighteen-year-old Lexa Hale, a determined recruit at the Terra Nova Military Academy, aims to honor her war-hero father by joining the elite ranks of the Starforge Corps. However, the brutal realities of combat quickly challenge her ideals.

Nuestra existencia está amenazada: las glaciaciones, los impactos de asteroides, la capacidad finita de la Tierra e incluso la lejana pero inevitable muerte del Sol son riesgos de tal magnitud que, si no abandonamos la Tierra, deberemos asumir la idea de nuestra extinción. Por eso, para Michio Kaku nuestro destino yace en las estrellas, no por la curiosidad o la pasión aventurera que los humanos llevamos dentro, sino por una simple cuestión de supervivencia.

Thirty years after the Syndicate Corporation saved Earth from climate-change extinction, SynCorp’s Five Factions rule the solar system with an iron fist wrapped in a velvet glove. Food, entertainment, safety, security - SynCorp provides it all. In return, the Company requires complete loyalty and obedience to corporate law.

The unabridged and enhanced 2nd edition of Zetetic Astronomy, formulated in the 19th century by Samuel Rowbotham, presents a flat-earth cosmology grounded in direct sensory observation rather than theoretical abstraction. Rejecting Newtonian and Copernican astronomy, Rowbotham argued that the Earth is a flat, stationary plane with the Sun, Moon, and stars moving in circular paths above it, asserting that empirical evidence—such as the apparent flatness of horizons and the behavior of water surfaces—supports this model.
