El relato del conocimiento del universo inabarcable, desde la mirada al cielo con el ojo desnudo hasta las sondas enviadas a años luz de la Tierra: una historia que tiene más de 3.600 años de antigüedad.La tarea de resumir más de tres milenios de investigaciones sobre el cielo parece imposible, más difícil aún parece presentarla de modo que pueda ser conocido por cualquier tipo de oyente, independientemente del conocimiento del mismo.

In the spring of 1848, rumors began to spread that gold had been discovered in a remote spot in the Sacramento Valley. A year later, newspaper headlines declared "Gold Fever!" as hundreds of thousands of men and women borrowed money, quit their jobs, and allowed themselves - for the first time ever - to imagine a future of ease and splendor.

In the late nineteenth century, people were obsessed by one of the last unmapped areas of the globe: The North Pole. No one knew what existed beyond the fortress of ice rimming the northern oceans. On July 8, 1879, the USS Jeannette set sail from San Francisco to cheering crowds in the grip of "Arctic Fever." The ship sailed into uncharted seas, but soon was trapped in pack ice. Two years into the harrowing voyage, the hull was breached. Amid the rush of water and the shrieks of breaking wooden boards, the crew abandoned the ship.

It was November 1806. The explorers had gone without food for one day, then two. Their leader, not yet thirty, drove on, determined to ascend the great mountain. Waist deep in snow, he reluctantly turned back. But Zebulon Pike had not been defeated. His name remained on the unclimbed peak-and new adventures lay ahead of him and his republic. In Citizen Explorer, historian Jared Orsi provides the first modern biography of this soldier and explorer, who rivaled contemporaries Meriwether Lewis and William Clark.

An exciting new audiobook on the greatest explorers in history and how their discoveries shaped the modern world. Whether it is Rabban Bar Sauma, the 13th-century Chinese monk commissioned by the Mongols to travel West form a military alliance against the Islam; Marco Polo, who opened a window to the East for Europe; or Captain James Cook, whose maritime voyages of discovery created the global economy of the 21st century, each of these explorers had an indelible impact on the modern world. This audiobook will look at the 11 greatest explorers in history.

In the final days of World War II, with the ravenous Red Army marching across Czechoslovakia, a wily band of American soldiers did the unexpected: They teamed up with the Nazis and went behind enemy lines to save the world's rarest horses from imminent extinction at the hands of the Russians - including the exquisite white Lipizzaner, whose bloodlines date back to Genghis Khan.

For the first time ever Roland Huntford presents each man's account of the race to the South Pole in their own words. In 1910, Robert Falcon Scott and Roald Amundsen set sail for Antarctica, each from his own starting point, and the epic race for the South Pole was on. 2010 marks the centenary of the last great race of terrestrial discovery. For the first time Scott's unedited diary entries run alongside those of Amundsen and Bjaaland, never before translated into English.

On their journey westward, Lewis and Clark demonstrated an amazing ability to identify the new plants and animals they encountered, and their observations enriched science's understanding of the trans-Mississippi West. Others have written about their discoveries and have faithfully cataloged their findings; now a 21st-century biologist reexamines some of those discoveries in the light of modern science to show for the first time their lasting biological significance.

The story of the rise of modern navigation technology, from radio location to GPS—and the consequent decline of privacy. What does it mean to never get lost? You Are Here examines the rise of our technologically aided era of navigational omniscience—or how we came to know exactly where we are at all times. Filled with tales of scientists and astronauts, inventors and entrepreneurs, You Are Here tells the story of how humankind ingeniously solved one of its oldest and toughest problems—only to herald a new era in which it’s impossible to hide.

Everywhere hailed as a masterpiece of historical adventure, this enthralling narrative recounts the experiences of 12 American sailors who were shipwrecked off the coast of Africa in 1815, captured by desert nomads, sold into slavery, and subjected to a hellish two-month journey through the bone-dry heart of the Sahara. The ordeal of these men - who found themselves tested by barbarism, murder, starvation, death, dehydration, and hostile tribes that roamed the desert on camelback - is made indelibly vivid in this gripping account of courage, brotherhood, and survival.

In February 1959, a group of nine experienced hikers in the Russian Ural Mountains died mysteriously on an elevation known as Dead Mountain. Eerie aspects of the incident—unexplained violent injuries, signs that they cut open and fled the tent without proper clothing or shoes, a strange final photograph taken by one of the hikers, and elevated levels of radiation found on some of their clothes—have led to decades of speculation over what really happened.

The Last Viking unravels the life of the man who stands head and shoulders above all those who raced to map the last corners of the world. In 1900, the four great geographical mysteries - the Northwest Passage, the Northeast Passage, the South Pole, and the North Pole - remained blank spots on the globe. Within twenty years Roald Amundsen would claim all four prizes.

The mysterious disappearance of Michael Rockefeller in remote New Guinea in 1961 has kept the world, and even Michael's powerful, influential family, guessing for years. Now, Carl Hoffman uncovers startling new evidence that finally tells the full, astonishing story.

Long at the margins of global affairs and at the edge of our mental map of the world, the Arctic has found its way to the center of the issues which will challenge and define our world in the twenty-first century: Energy security and the struggle for natural resources, climate change and its uncertain speed and consequences, the return of great power competition, the remaking of global trade patterns…

At a time when the edge of American settlement barely reached beyond the Appalachian Mountains, two visionaries, President Thomas Jefferson and millionaire John Jacob Astor, foresaw that one day the Pacific would dominate world trade as much as the Atlantic did in their day. Just two years after the Lewis and Clark expedition concluded in 1806, Jefferson and Astor turned their sights westward once again. Thus began one of history's dramatic but largely forgotten turning points in the conquest of the North American continent.

On March 8, 1421, the largest fleet the world had ever seen set sail from China. Its mission was to "proceed all the way to the ends of the earth to collect tribute from the barbarians beyond the seas" and unite the whole world in Confucian harmony. When it returned in October 1423, the emperor had fallen, leaving China in political and economic chaos. The great ships were left to rot at their moorings and the records of their journeys were destroyed. Lost in China's long isolation that followed was the knowledge that Chinese ships had reached America 70 years before Columbus.

An eminent scholar finds a new American history in the Hispanic past of our diverse nation. The United States is still typically conceived of as an offshoot of England, with our history unfolding east to west beginning with the first English settlers in Jamestown. This view overlooks the significance of America's Hispanic past. With the profile of the United States increasingly Hispanic, the importance of recovering the Hispanic dimension to our national story has never been greater. This absorbing narrative begins with the explorers and conquistadores who planted Spain's first colonies in Puerto Rico, Florida, and the Southwest.

When Columbus first returned to Spain from the Caribbean, he dazzled King Ferdinand and Queen Isabella with exotic parrots, tropical flowers, and bits of gold. Inspired by the promise of riches, countless seafarers poured out of the Iberian Peninsula and wider Europe in search of spices, treasure, and land. Many returned with strange tales of the New World. Curiosity began to percolate through Europe as the New World’s people, animals, and plants ruptured prior assumptions about the biblical description of creation.

Between 1896 and 1899, thousands of people lured by gold braved a grueling journey into the remote wilderness of North America. Within two years, Dawson City, in the Canadian Yukon, grew from a mining camp of four hundred to a raucous town of more than thirty thousand. The stampede to the Klondike was the last great gold rush in history. Scurvy, dysentery, frostbite, and starvation stalked all who dared to be in Dawson. And yet the possibilities attracted people from all walks of life.

In 1826, when the story begins, the region was claimed by both Mexico and the United States. Neither country knew much about the lands crossed by such rivers as the Guadalupe, Brazos, Nueces, Trinity, and Rio Grande. Jean Louis Berlandier, a French naturalist, was part of a team sent out by the Mexican Boundary Commission to explore the area. His role was to collect specimens of flora and fauna and to record detailed observations of the landscapes and peoples through which the exploring party traveled.
