Earth Space Science

Riveting and timely, a look at the research that is transforming our understanding of the cosmos in the quest to discover whether we are alone.

Betrayed by allies. Beset by new foes. Earth faces its darkest hour since the Xaros invasion. The Toth come to the solar system with a fleet of warships, and they demand the only tool that can rekindle the human race. It falls on Marine Lieutenant Hale to negotiate a pact that will save the human race at the cost of its soul - or start a war with a race of alien predators.

The heliopause protected Earth, keeping us safe from a violent galaxy. Or so we thought. Who knew it did more than keep us guarded? Who understood that its integrity was the only thing holding our beginner’s protection in place? If we'd known—if we’d understood, we’d have waited longer, a hell of a lot longer to pierce its veil. But when the USM Arrowheart passed through it and left our solar system, that protection ended and all hell broke loose. The aliens who'd been watching, waiting, and biding their time were ready. We weren’t. But there was hope.

Following their successful escape from Androchida Prime’s capital city, Sir Chuck and the rest of the Phantoms find themselves mystified by unsettling news. The leader of the Blood Guard resistance, famed General Cordan, has defected to the AE. But while many doubt the veracity of the development, more pressing intel awaits: the empire is planning to invade the Sci-Rung home world.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

On the moon of Psyche, Lucian Abrantes, the Chosen of the Manifold, must start from humble beginnings, growing his single world into an empire. He must unite disparate factions that don’t recognize his legitimacy.

The galaxy burns. The enemy, a race of alien scorpions, storms from star to star. Planets smolder in their wake. Across the galaxy, they hunt humans. Long ago, we humans had a planet of our own. Long ago, we could have resisted the scorpions. But today we are refugees. We are lost in darkness. We haven't seen Earth in 2,000 years. We, the last humans, must band together. We must resist. We must fight the scorpions. And we must find Earth! Only Earth can unite us. Only Earth can kindle our hope. Only on Earth can we defend our species.

The basilisks, cruel alien serpents, attacked our world. They bombed us. Hunted us. Butchered us without pity. But now we will be the hunters. We will assemble a fleet. We will cross the vastness of space. And for the first time, we will strike the enemy on his own soil. It's a time for courage. A time for heroes. We will no longer hide in bunkers. We will no longer die like sheep. Freedom will be won with blood and fire. Freedom will be the legacy of Earth. We are the last humans. And we will win!

We are the last humans. We are hunted. We are refugees. We must return to Earth. The alien scorpions attack us across the galaxy. They butcher millions. Humans are now an endangered species. But we have not given up. We still have a few starships. We still have some hope. And we have a map home. On Earth, we can be free again. On Earth, we can stand tall. On Earth, we can rebuild what we have lost. Earth is but an echo, calling from beyond the darkness. We will answer her call. We will find our lost world. We will defeat our enemies. We will rise again!

Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

The battle lines are collapsing, and the Legion of Wolves cannot hold back the tide. Luna and Earth are both falling to the enemy, and there is little hope as the defense is pushed back on all sides. But when Wolf learns about a race in a distant part of the galaxy that has successfully fought the vanhat to a standstill, he decides to launch an expedition to seek their help. The AI Collective has also learned about the expedition, though, and intends to kill humanity before they can find aid.

L'ultime mission de Patrick « Wic » Finnegan avant son départ en retraite l'envoie dans la froideur des Hautes terres sous-glaciaires d'Ellsworth. Quand il voit ce que l'équipe a découvert, il n'en croit pas ses yeux. Il est loin d'imaginer la violence qui va en découler : un portail s'ouvre et libère un ouragan de fureur qui se déchaîne sur l'humanité. De l'Antarctique aux rues de Manhattan, Wic et son équipe vont tester leurs limites en se battant pour repousser la menace qui pèse sur la Terre.

Humanity pushed its way to the stars—and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild. But the Gbaba can detect the emissions of an industrial civilization, so the human rulers of Safehold have taken extraordinary measures: with mind control and hidden high technology, they've built a religion in which every Safeholdian believes, a religion designed to keep Safehold society medieval forever.

According to Sumerian scholar Zecharia Sitchin, a superior race of beings once inhabited our world. In The 12th Planet—the product of 30 years of intensive research—Sitchin persuasively argues that humanity sprang from extraterrestrial forebears. In this remarkable account, you'll hear the story of how these ancient visitors traveled to Earth from the stars and planted the genetic seed that would ultimately blossom into a remarkable species—the human being.

Two hundred years ago, a fleet of colony ships left Earth and started a settlement on Proxima Centauri. Centurion Space Force pilot Nathan Stacker didn't expect to return home to find his wife dead. He didn't expect the murderer to look just like him, and he definitely didn't expect to be the one to take the blame. But his wife had control of a powerful secret. A secret that stretches across the light years between two worlds and could lead to the end of both. Now that secret is in Nathan's hands, and he's about to make the most desperate evasive maneuver of his life.

One hundred and fifty years from now, in a world where Africa is the dominant technological and economic power, and where crime, war, disease and poverty have been banished to history, Geoffrey Akinya wants only one thing: to be left in peace, so that he can continue his studies into the elephants of the Amboseli basin. But Geoffrey's family, the vast Akinya business empire, has other plans.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

Only an ember of humanity survived the first Xaros invasion. Now the Xaros return to deliver the final blow to Earth and her defenders. A moon carrying an armada of Xaros drones unleashes its deadly cargo on the solar system. Fortress Mars stands between the enemy and an ill-defended Earth. While the battle rages over the red planet, the Breitenfeld must launch a desperate mission to Pluto to cut off enemy reinforcements. Earth stands on the brink of ruin, and humanity needs every hero it can find to turn back the tide of destruction.

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.
