When radio telescope operators Lauren Stelleck, a woman with a special gift enabling her to literally see certain sounds, and Steve Andrews, a diehard sci-fi geek, detect a signal like no other at Jodrell Bank in England, a chain of events is unleashed that propels Earth towards all-out nuclear war. Can Lauren and Steve unlock the secret of the signal before our species tears itself apart?

The Iglax Star Empire’s tried twice now to throttle this upstart species before they could expand beyond Sol. They once used humans for cheap mining, cheap labor, and cheap laughs. But with each attempt, humanity’s gotten stronger, spread across more star systems, and found new allies. Now the Iglax are preparing for war.

Alien fighters bombard Earth's ruins. Cannibalistic aerobics instructors hunt the wastes. The last free survivors struggle against starvation and enslavement. It's become a world where friendship costs too dearly and heroics verge on suicide. One young man can't resist either until a fed-up AI steals him off the planet. Alone with only a sarcastic, broken-down starship, he braves a whole new verse full of strange new enemies and tech he barely understands.

The Scorched Earth in the title doesn't refer to the Human's homeworld. Rather it describes the path of death and destruction that Adam Cain burns on his way from Earth to the planet Juir as he seeks revenge for the killing of one of his closest friends. But there's more. Sherri and Arieel have been taken prisoner by the Juirean leader, with a date for their execution already set. The aliens may have thought Adam was dangerous before, but they ain't seen nothing yet.

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....

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.

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.

With the Milky Way galaxy engaged in a life-or-death struggle against the evil Sol-Kor Colony, Adam Cain and Riyad Tarazi are given the chance to end the war once and for all: Travel into another universe and assassinate the queen of the Sol-Kor. If their mission succeeds, it could end the war with a single stroke, saving trillions upon trillions of innocent creatures from the ravenous, flesh-eating invaders. If not...

The marauders, terrors from deep space, hit us hard. Our starships shattered. Our armies collapsed. Our cities crumbled. As Earth smolders, the marauders imprison us in camps. They farm us like cattle. They torture us for sport. Earth weeps. But there is hope. The Ghost Fleet, an ancient alien armada, might still exist in deep space. In a single starship, Sergeant Marco Emery and his friends seek this mythical fleet. They must find it. They must return with its might. Or the marauders will kill us all.

Turns out, not only is Ellie an alien, but an ancient and powerful relic housing the forbidden knowledge of a lost civilization is hidden deep within her genetic code. Suddenly, she's on the run from a malevolent Emperor who sees her as the key to ruling the galaxy.

They walk among us. They look just like us. They plot our doom. Some call them the scummers. Hybrids. Humans with alien DNA. Years ago, they hatched in alien labs. They came to Earth as sleeper agents. Since then, they’ve been mingling with our society. They teach our children. They cook our food. They tend to our elders. All the while waiting. Biding their time. Hiding in plain sight. And now they strike. With devastating force. With terrifying cruelty. They bring Earth to its knees.

The marauders, vicious alien predators, brought us to our knees. They destroyed our fleets. They burned our cities. They butchered millions. But now we fight back. Across the ruins of Earth, we rise in rebellion. In the depths of space, we seek allies. And our last warship prepares for one final battle. It's a time for heroes. A time to show our human pride. Because Earth is our home. Earth is our birthright. Earth is eternal. We will save it. Or we will die on our feet.

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.

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.

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.

Earth's Diaspora is well underway and the colonies are flourishing. There are Dynasties of The Accord, however, that resent Earth's expansion. Charli Morgan and Lucca Spelini each lead their respective teams from colony to colony, preventing interference and keeping the peace. Standing up to the Dynasties is one thing, but what happens when Lower Houses of The Accord start butting in?

This “accessible and always entertaining” (Booklist) combination of history, pop science, and in-depth reporting offers a fascinating account of the asteroids that hit Earth long ago and those streaming toward us now, as well as how prepared we are against asteroid-caused catastrophe.

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.

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.

On August 21, 2017, more than 10 million Americans will experience an awe-inspiring phenomenon: the first total eclipse of the sun in America in almost 40 years. In Sun Moon Earth, astronomer Tyler Nordgren illustrates how this most seemingly unnatural of natural phenomena was transformed from a fearsome omen to a tourist attraction. From the astrologers of ancient China and Babylon to the high priests of the Maya, Sun Moon Earth takes us around the world to show how different cultures interpreted these dramatic events.
