Showing results for "Astronomy" in Americas

In the decades after the Apollo program, American space shuttles flew over 130 missions and successfully completed over 98 percent of them, but unfortunately, the two most famous missions were the ones that ended tragically aboard the Challenger and Columbia. The Space Shuttle Challenger Disaster: The History and Legacy of NASA’s Most Notorious Tragedy chronicles the disaster from the origins of the Challenger mission to what went so terribly wrong.

On April 24, 1990, the Space Shuttle Discovery lifted off from Kennedy Space Center on the Space Shuttle Program’s 35th mission, but this was no ordinary mission. In its payload bay, Discovery was carrying the Hubble Space Telescope, with the objective of putting the telescope into orbit.

For the Maya, astronomy was not a purely scientific pursuit, but intimately linked to religious, mythological, and ideological elements that were of the highest importance. The celestial realm held a sacred nature, as did the many gods and goddesses that dwelt there, so for all Mesoamerican cultures, astronomy was a fundamental part of their everyday lives. Thus, astronomy was present in their calendars, religion, and even agriculture, and in close relation to astronomy, the concept of time was also an essential part of their worldview.

The Cold War is usually thought of in terms of fear, potential nuclear war, and espionage. While these were elements of the years between the end of World War II and the 1990s, the competition between the US and the USSR had some real benefits. Perhaps, the best and most impressive accomplishments during this time resulted from the Space Race.

Life in Space explores the many aspects and outcomes of NASAs research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASAs work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush's Vision for Space Exploration.

By the time the Hubble telescope reached orbit, it was already the world’s most famous telescope, but it was also the most scorned. The telescope cost nearly two billion dollars more to complete than anticipated, and to make matters worse, the first images it sent back were skewed. However, within about a year of fixing it, the telescope captured images of a major event in the solar system.

Mesoamerica is a historical region and cultural area in North America. It extends from approximately central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica. The first civilization in central and north America develops in about 1200 BC in the coastal regions of the southern part of the Gulf of Mexico. Known as the Olmec civilization, its early site is at San Lorenzo. In Mesoamerica the Maya civilization made the greatest progress in science and technology.

During the Age of Exploration, Native American tribes fell victim to European conquerors seeking legendary cities made of gold and other riches, attempts that were often being made in vain. And yet, of all the empires that were conquered across the continent, the one that continues to be most intimately associated with legends of gold and hidden riches is the Inca Empire.

Many ancient civilizations have influenced and inspired people in the 21st century, and the Greeks and Romans continue to fascinate the West today, but of all the world’s civilizations, none have intrigued people more than the Mayans, whose culture, astronomy, language, and mysterious disappearance all continue to captivate people. In the past decade especially, there was a renewed focus on the Maya, whose advanced calendar led many to speculate the world would end on the same date the Mayan calendar ended in 2012.

America's First Great Eclipse takes listeners on a thrilling historical journey, revealing that 19th-century Americans were just as excited about a total solar eclipse as we are today...and, like us, were willing to travel thousands of miles to see it.
