For years, they stalked us. Kidnapped us. Dissected us. For years, we feared them. Some call them "gray aliens". Some claim they crashed in Roswell. Others say they're just a myth. But legends often spring from terrifying truths. There are monsters in the dark. And their evil knows no bounds. We've faced aliens before. But nothing like this. This enemy is stronger, smarter, and crueler by far. And they want to kill us all. But we refuse to fall. We will muster all our courage. All our strength. We will tell the enemy: "Earth will rise!"

The time of the Great Exodus is over. Centuries have passed. Earth is overpopulated, and the fate of the colonists who traveled to the stars is unknown. An attempt to start the second wave of expansion has led to a shocking discovery: All accessible planets located within one hyperjump from the Solar System have been settled during the Great Exodus. The colonists have created unique and distinctive civilizations - but none of that matters when the survival of billions of Terrans is at stake.

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.

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.

In space, mutiny means death - that’s why Inspector General Park Yerim is taking her investigation so seriously. The alleged mutineer is Captain Nicolau Aames, whose command of the massive Earth-Mars vessel Aldrin has come under fire. The vast System Initiative says he disobeyed orders, but his crew swears he’s in the right. En route to Mars, Park gathers testimony from the Aldrin’s diverse crew, painting a complex picture of Aames’s character: his heroism, his failures, even his personal passions.

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.

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.

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.

United we stand. Divided we fall. We stood together once. United. Proud. Humanity was one. Together we colonized the stars. Together we built an empire. That was a long time ago. Today humanity is fractured. Earth and Mars clash in war. Brother fights brother. Our fleets once faced the stars. Today they face each other in battle. Our empire frays. Hearts that once blazed with courage now burn with hatred. Meanwhile the true enemy draws ever nearer.

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.

Poised to reconquer humanity's home, Captain Absen and Conquest are confronted with a new enemy that upsets the balance of power and changes everything EarthFleet expected. Their struggle to free Earth becomes instead a desperate battle for sheer survival as they contemplate the unthinkable: total annihilation.

For twenty years, Alex has believed that his gene-edited super-algae will slow and even reverse the effects of climate change. His obsession with his research has jeopardized his marriage, his relationships with his kids, and his own professional future. When the Son sisters, founders of the colossal tech company Sensus, offer him a chance to complete his research, he seizes the opportunity. The catch? His lab will be in outer space on Parallaxis, the first-ever luxury residential space station built for billionaires.

For years, Earth's heroes fought united. They faced alien armies in war. They defended Earth as friends. As a fellowship. Now they break apart. Lailani de la Rosa, heroine of the Alien Wars, aligns herself with a new enemy. She rises to lead the scummers, a breed of human-alien hybrids.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

No one on Earth knows the seeds of the world’s destruction just fell from space. Tiana knows what duty means though. It's why all her friends are dead. Alone on a primitive world. All her all her technology at the bottom of the ocean. Outnumbered by deadly enemies only she can bring to justice. If she fails her mission now, another sentient species will fall. And the Tyrant Empire will rise again - because Earth has just been infected with a fatal parasite.

Mind Openers 2.0 is the second installment in a two-part set. It takes a fresh look at relativity, cosmology, and quantum theory by imagining a “sandbox universe”, in which space and time are treated as tangible and visualizable phenomena. In addition to providing an intuitive feel for the physics, the model makes a number of acutely unexpected predictions. The author is a geophysicist (MSc, fellow of geoscientists, Canada) and educator, who specializes in translating scientific material for the non-expert.

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?
