Space Science

Nine hundred thousand years ago, something annihilated the Amarantin civilization just as it was on the verge of discovering space flight. Now one scientist, Dan Sylveste, will stop at nothing to solve the Amarantin riddle before ancient history repeats itself. With no other resources at his disposal, Sylveste forges a dangerous alliance with the cyborg crew of the starship Nostalgia for Infinity. But as he closes in on the secret, a killer closes in on him because the Amarantin were destroyed for a reason.

The Merry Band of Pirates are in desperate trouble after the end of their last mission, and the real danger to humanity is just getting started. Hostile aliens have discovered there is something odd going on with wormholes in the galaxy, and their investigations could lead to finding a shortcut to Earth....

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

The year is 3326. Nigel Sheldon, one of the founders of the Commonwealth, receives a visit from the Raiel - self-appointed guardians of the Void, the enigmatic construct at the core of the galaxy that threatens the existence of all that lives. The Raiel convince Nigel to participate in a desperate scheme to infiltrate the Void. Once inside, Nigel discovers that humans are not the only life-forms to have been sucked into the Void. The humans trapped there are afflicted by an alien species of biological mimics.

A sweeping account of the century of experimentation that confirmed Einstein's general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory.

After the Soviet Union proved to the United States that it possessed an operational intercontinental ballistic missile with the launch of Sputnik in October 1957, the world watched anxiously as the two superpowers engaged in a game of nuclear one-upmanship. Amid this rising tension, eccentric physicist Nicholas Christofilos brought forth an outlandish, albeit ingenious, idea to defend the US from a Soviet attack: detonating nuclear warheads in space to create an artificial radiation belt that would fry incoming ICBMs. Known as Operation Argus, this plan is the most secret and riskiest experiment in history, and classified details of these nuclear tests have been long obscured.

How many Carl Sagan fans know that while the renowned scientist was at Stanford University, he produced a controversial paper, funded by a NASA research grant, that concludes that ancient alien intervention may have sparked human civilization? Author Donald L. Zygutis lays out a compelling case that points to a cover-up by the Pentagon and NASA, who may have buried it soon after it was written. How significant is the Stanford paper?

In 2205, the 19th Amendment has long been repealed and women are only valued for their utility. The Earth's economy depends on an insular group of linguists who "breed" women to be perfect interstellar translators until they are sent to the Barren House to await death. But instead, these women are slowly creating a language of their own to make resistance possible. Ignorant to this brewing revolution, Nazareth, a brilliant linguist, and Michaela, a servant, both seek emancipation in their own ways. But their personal rebellions risk exposing the secret language.

The original teleplay that became the classic Star Trek episode, with an expanded introductory essay by Harlan Ellison, The City on the Edge of Forever has been surrounded by controversy since the airing of an "eviscerated" version - which subsequently has been voted the most beloved episode in the series' history. In its original form, The City on the Edge of Forever won the 1966-67 Writers Guild of America Award for Best Teleplay. As aired, it won the 1967 Hugo Award.

It seemed the unthinkable had happened. Someone had actually targeted the Ghalian, an order of assassins known and feared across the systems. It was madness. Only a fool would go after the likes of them. But, it seemed, the galaxy had no shortage of fools. Retaliation most bloody was in order, and one man stood ready to spring into action. Hozark was his name, and he was no ordinary man. He was a Master Ghalian, an assassin skilled in the ways of death. Practical, mechanical, magical, to him it made no difference.

The Laconian Empire has fallen, setting the 1,300 solar systems free from the rule of Winston Duarte. But the ancient enemy that killed the gate builders is awake, and the war against our universe has begun again.

Brought up by unfriendly, ossifying nuns, ancient retainers, and countless skeletons, Gideon is ready to abandon a life of servitude and an afterlife as a reanimated corpse.

But the price of that knowledge may be higher than she can pay.

The best-selling, epic space adventure, Freedom's Fire: the complete series of six audiobooks, in one bundle.

The galaxy remembers Hadrian Marlowe as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives - even the emperor himself - against Imperial orders. But Hadrian was not a hero. He was not a monster. He was not even a soldier. Fleeing his father and a future as a torturer, Hadrian finds himself stranded on a strange, backwater world.

Hadrian Marlowe is lost. For half a century, he has searched the farther suns for the lost planet of Vorgossos, hoping to find a way to contact the elusive alien Cielcin. He has not succeeded, and for years has wandered among the barbarian Normans as captain of a band of mercenaries. Determined to make peace and bring an end to nearly 400 years of war, Hadrian must venture beyond the security of the Sollan Empire and among the Extrasolarians who dwell between the stars.

Out of the Silent Planet is the first novel of the Cosmic Trilogy, considered to be C.S. Lewis' chief contribution to the science fiction genre.
