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.

El hombre tiende siempre a inventar utopías y a perseguir quimeras, ya desde la antigüedad territorios como la Atlántida o las Islas Afortunadas, habían sido visitadas por viajeros que traían descripciones de animales increíbles y tesoros infinitos, otro tanto pasaba con regiones como la India de la que se contaban también numerosas leyendas fantásticas que fueron confirmadas, en algunos casos, por hombres que estuvieron allí, las tropas de Alejandro Magno por ejemplo.

La historia que se esconde detrás de una de las mejores novelas de aventuras de todos los tiempos. En 1875, Henry Rider Haggard escribe Las minas del rey Salomón, probablemente una de las mejores novelas de aventuras de todos los tiempos. Muchos intuyen pero pocos conocen el correlato histórico que se oculta detrás de esta novela: la lucha entre colonos ingleses y holandeses contra las tribus africanas por el control de los recursos naturales y de los territorios.

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.

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.

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.

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.

These Chronicles could have been authored by Thomas Jefferson had he been so inclined to do so. He and Captain Meriwether Lewis spent long nights tracing its daily record of "Courses and Distances" onto brown paper on the floor of the East Wing of the White House. After Lewis's untimely death, Jefferson instead relegated the job to Captain William Clark. As a result, the narrative of the expedition has, until now, never been told as Captain Meriwether Lewis intended it to be.

This audio-article explores the idea that L'Anse aux Meadows could be the gateway to the Viking Vinland settlement mentioned in the Scandinavian sagas and possibly founded by Leif Ericson. L'Anse aux Meadows is still the only widely accepted evidence of pre-Columbian contact with North America.

Many have believed that Atlantis was a fiction created by Plato. Well Plato was not the first to write about it. We have found a very much earlier document. It was written in 9619 BC, about 9,250 years before Plato's writing. Further, we have assembled enough evidence in terms of archeological finds and scientific facts to provide convincing proof that Atlantis really did exist. And we have found the remains. We structure the evidence to answers 3 basic questions: how was it created; did it leave evidence; how was it destroyed?

The year 2009 marks the 400th anniversary of Henry Hudson’s discovery of the majestic river that bears his name. Just in time for this milestone, Douglas Hunter, sailor, scholar, and storyteller, has written the first book-length history of the 1609 adventure that put New York on the map. Hudson was commissioned by the mighty Dutch East India Company to find a northeastern passage over Russia to the lucrative ports of China. But the inscrutable Hudson, defying his orders, turned his ship around and instead headed west....

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.

Rife with captivating details of survival in an icy wilderness, this reimagining of the famous 1910 expedition to the South Pole, told in Cherry's voice, is an unforgettable tale of courage and camaraderie.

When gold was first discovered on the American River above Sutter's Fort in January 1848, California was sparsely populated frontier territory not yet ceded to the United States from Mexixo. The discovery triggered a massive influx as hundreds of thousands of people scrambled to California in search of riches, braving dangerous journeys across the Pacific, around Cape Horn, and through the Isthmus of Panama, as well as across America's vast, unsettled wilderness. Cities sprang up overnight, in response to the demand for supplies and services of all kinds.

In 1856 Paul Du Chaillu marched into the equatorial wilderness of West Africa determined to bag an animal that, according to legend, was nothing short of a monster. When he emerged three years later, the summation of his efforts only hinted at what he'd experienced in one of the most dangerous regions on earth. Armed with an astonishing collection of zoological specimens, Du Chaillu leapt from the physical challenges of the jungle straight into the center of the biggest issues of the time.

Il viaggio di Darwin fu un'esperienza unica nella storia della scienza: una rivoluzione scientifica nata per mare, dopo che un giovane geologo e naturalista si era imbarcato quasi per caso nel 1831 su un brigantino di Sua Maestà diretto nei Mari del Sud. Cinque anni di mal di mare, di osservazioni meticolose, di strani esperimenti antropologici e di pensieri ancora embrionali. Nessuna illuminazione improvvisa incontrando iguana, fringuelli e testuggini. Solo molti dubbi, qualche buona domanda, tanta curiosità e la capacità di collegare fatti sparsi.

La scoperta dell'America non fu soltanto la scoperta del Nuovo Mondo. Fu, prima ancora, la verifica della possibilità di una nuova maniera di fare i conti con ciò che esiste, attraverso uno sguardo e una pratica che hanno definito la natura dell'intera modernità e che ancora oggi restano in sostanza i nostri. Quello di Colombo fu davvero uno strano andare, di cui paradossalmente più tempo passa meno di certe si conosce. Una cosa è sicura: il viaggio di Colombo ha caratteristiche uniche.
