Astronomy History

This book includes key presidential speeches on the exploration of space from President Kennedy to President Trump. It includes the fascinating speech that Nixon had written, and subsequently recorded, but fortunately never delivered. The speech was in the event that the Apollo 11 mission did not succeed. Others include Kennedy's bold 1961 speech setting out the goal of sending a man to the moon, which was then achieved within the decade.

In 1910, Mary Acworth Evershed (1867-1949) sat on a hill in southern India staring at the moon as she grappled with apparent mistakes in Dante's Divine Comedy. Was Dante's astronomy unintelligible? Or was he, for a man of his time and place, as insightful as one could be about the sky? As the 20th century began, women who wished to become professional astronomers faced difficult cultural barriers, but Evershed joined the British Astronomical Association and, from an Indian observatory, became an experienced observer of sunspots, solar eclipses, and variable stars.

The question of man’s place in the extended universe has been pondered by every known culture since the beginning of recorded history. Naturally, as technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. While incidents like the one at Roswell led to conspiracies and a craze among those who insisted the government was hiding proof of extraterrestrials’ existence, governments across the world were actually secretly studying UFO sightings by the mid-20th century.

When people look up into the night sky, the stars seem fixed and immutable, as unchanging as the darkness of space itself, but the truth is that stars are born, live, and die in a never-ending cycle of creation and annihilation. These cycles stretch over such vast spans of time that to short-lived humans, they seem to last forever. No one knows just how many stars there are, but their number is almost beyond comprehension.

Thanks to ancient Greece, we know more about philosophy, politics, the democratic system, mythology, art, the Olympics, and many, many lingual references imbedded in almost every European language. Ancient Greece has had a significant impact on many concepts we still hold true today.
