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.

In 1959, the Soviet probe Luna 3 took the first photos of the far side of the Moon. Even in their poor resolution, the images stunned scientists: The far side is an enormous mountainous expanse, not the vast lava plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. When the Earth Had Two Moons is an astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists.

It’s been eight years since an alien invasion drove a small surviving group of settlers to seek refuge in an underground shelter. Cut off from the rest of humanity, the ragtag band has maintained a narrowly functioning colony due to communal effort and salvage runs. Alex Archer has her own duties as a dog handler. While this off-world colony may be harsh, Ash, Alex’s black shepherd raised to sense threats, makes living in it a little nicer.

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.

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.

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.

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.

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.

As a sci-fi author with a hit TV show, I have a few ideas about what alien invaders are supposed to look like. In my stories, they’re technologically advanced monsters, with tentacles, and no faces. Turns out I was right about the technology. And about how angry they’d be. But the way they look is more terrifying than even I could have imagined. They look exactly like us. Because they are us.

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.

Former elite Federation soldier, now turned space pirate, Jackson Burke has done his best to turn his life around - for the better. He isn't prepared when fate leaves a woman's safety totally in his hands. Since heroes don't leave a damsel in distress - and despite being outlaw pirates - the crew considers themselves the good guys, so Jackson assumes responsibility for the beauty.

Aerospace journalist Joe Pappalardo has witnessed space rocket launches around the world, from the jungle of French Guiana to the coastline of California. In his comprehensive work Spaceport Earth, Pappalardo describes the rise of private companies in the United States and how they are reshaping the way the world is using space for industry and science. Spaceport Earth is a travelogue through modern space history as it is being made.

Jane is the only person left on the planet, minding the only business left: a gift shop. She wasn’t born on Earth, but her ancestors were; they lived there before the AI in charge of geoengineering failed and the oceans got too hot to sustain the terrestrial food web and before humans took off to colonize other planets. She’s heading to college on Jupiter in the fall of 3020, so her days on the home planet—selling “American Epoch” postcards, “History: The Poster!” and “War: The Soundtrack” to tourists from the suburbs of Europa—are numbered.

They came from deep space. They came to destroy us. Fifty years ago bloodthirsty aliens devastated the Earth. Most of humanity perished. We fell into darkness. But now we rise from the ashes. Now we fight back. Marco Emery was born into the war. After his mother is killed, he joins the Human Defense Force, Earth's ragtag army. Emery must survive basic training, become a soldier, and finally face the aliens in battle. Against the alien onslaught, Earth stands alone. But we will fight. We will rise. We will win.

At last, the Earth and the Colonial Union have begun formal discussions about their relationship in the future - a chance for the divisions in humanity to be repaired. The diplomats and crew of the Clarke are on hand to help with the process, including Ambassador Ode Abumwe and CDF Lieutenant Harry Wilson, both of whom were born on Earth. But not everyone wants the human division to be repaired.... And they will go to great lengths to make sure it isn’t....

They’re here. They’ve arrived. And they’re all eyes. The Voltarian scouting party - illegal aliens extraordinaire - on a top-secret expedition led by one Jettero Heller, Royal Officer of the Fleet. His mission: rescue the planet from pollution - and make it safe for the upcoming invasion. His problem: The planet may not want to be saved - and the invasion may just be a trick.

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.

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.

Earth is in turmoil. The enemy is bearing down on us with every warship they have, and our only allies are in chaos. Our one hope for survival is Andy Clanton - a hack science fiction writer trying to convince some aliens that humans are worth saving. It’s an uphill battle, because to the aliens, we are the monsters. We look just like their sworn enemies, the Tevynians, who’ve sworn to wipe out both our civilizations. When everything falls apart and the fate of the galaxy is on the line, can Andy Clanton pull our fat out of the fire?

In 1977, two extraordinary spacecraft called Voyager were launched to the stars. Affixed to each Voyager craft was a gold-coated copped phonograph record as a message to possible extra-terrestrial civilizations that might encounter the spacecraft in some distant space and time.
