"FASCINATING . . . MEMORABLE . . . REVEALING . . . PERHAPS THE BEST OF CARL SAGAN'S BOOKS." --The Washington Post Book World (front page review) In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time. Future generations will look back on our epoch as the time when the human race finally broke into a radically new frontier--space. In Pale Blue Dot Sagan traces the spellbinding history of our launch into the cosmos and assesses the future that looms before us as we move out into our own solar system and on to distant galaxies beyond. The exploration and eventual settlement of other worlds is neither a fantasy nor luxury, insists Sagan, but rather a necessary condition for the survival of the human race. "TAKES READERS FAR BEYOND Cosmos . . . Sagan sees humanity's future in the stars." --Chicago Tribune "From the Trade Paperback edition."

Reissued after seventy-five years out of print -- and in hardcover for the first time in a generation -- Lucky Starr and the Pirates of Asteroids is the second book in the Lucky Starr series written by the legendary Isaac Asimov, author of Foundation, the Galactic Empire series, and I, Robot. Twenty-five years before, Lucky Starr's parents had been destroyed during a pirate raid on the Terrestrial Empire. Now Lucky was a man, and an officer of the Council of Science. His ship was heavily armed and the pirates were at hand. The time for sweet blaster vengeance was near! Lucky Starr's Ergometrics probed space with widely stretching fingers. It detected many ships, but Lucky watched only for the one which he would recognize with certainty the instant it appeared. Nor did he fail. At a distance of twenty-million miles, the first quiverings roused his suspicions. At 100-thousand miles, his telescope showed it as a faint dot. At ten thousand, it had form and shape -- it was the flagship of Anton, the pirate chieftain! At a thousand miles, Lucky sent out his first message -- a demand that Anton return to Earth. At one hundred miles, Lucky received his reply -- a blast of energy that made his generators whine and rocked his ship as if he had collided with another. Lucky's tired face took on a drawn look. Anton's ship was heavily armed. It was not what Lucky had expected ...

From Hugo and Nebula Award-winning author Robert Silverberg comes, To Open The Sky. The Atom was their God-but there was something stronger... At the beginning of the 22nd century, Earth colonies were established on Mars and Venus. But the ultimate dream - to travel to the stars - was still an impossibility. Cults, fads, madnesses of various kinds swept the population. The maddest--and so far the most permanent--were the Vorst worshipers, the atom adorers, the believers in immortality through technology. Yet there were the Harmonists, who believed that technology could never do it. And the hatred between the two factions was too deep to be reconciled - until a conflict on Venus between a Vorster priest and his Harmonist opponent resulted in unexpected developments.
