NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Solar Eclipse Of May 12, 1706
The solar eclipse on May 12, 1706 was a total eclipse. The astronomic event, part of the Saros 133 cycle, took place during the Spanish War of Succession, crossing Spain, France and Northern Italy: for this reason it was seen at the time as a metaphor and a premonitory sign of the decline of King Louis XIV of France (known as the ''Sun King'') "occulted" by the Great Alliance. Description The eclipse was visible in north and west Africa along with all Europe and its islands, Asia including the most of Middle East and almost all of Siberia and a small part of northeastern North America and the northern islands. It was also visible in the Atlantic. A very small portion occurred in the Southern Hemisphere almost entirely over the ocean. It was part of solar saros 133. The umbral portion which was as far as 242 km (150 mi), it included areas that were 150 miles (250 km) northwest of the Cape Verdean island of Santo Antão (then a Portuguese colony) in the Atlantic, ...

Solar Eclipse Of May 3, 1715
__NOTOC__ A total solar eclipse occurred on 3 May 1715. It was known as Halley's Eclipse, after Edmond Halley (1656–1742) who predicted this eclipse to within 4 minutes accuracy. Halley observed the eclipse from London where the city of London enjoyed 3 minutes 33 seconds of totality. He also drew a predictive map showing the path of totality across the Kingdom of Great Britain. The original map was about 20 miles off the observed eclipse path, mainly due to his use of inaccurate lunar ephemeris. After the eclipse, he corrected the eclipse path, and added the path and description of the 1724 total solar eclipse. Drawing upon lunar tables made by the first Astronomer Royal John Flamsteed, William Whiston produced a more technical predictive eclipse map around the same time as Halley. Both Halley's and Whiston's maps were published by John Senex in March 1715. Totality was observed in the Kingdom of Great Britain from Cornwall in the south-west to Lincolnshire Lin ...

Solar Eclipse Of May 22, 1724
A total solar eclipse occurred on May 22, 1724. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Observations This solar eclipse crossed Ireland and Great Britain near sunset, north-west to south-east track, from Galway to southern Wales and Devon in the west, eastwards to Hampshire and Sussex, but passing to the south of London. It was to be 203 years before a total solar eclipse was next witnessed from the British mainland, which had previously seen a total eclipse just nine years before, and Ireland will not see a total solar eclipse until 2090. It crossed what would later become t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of July 14, 1749
An annular solar eclipse occurred on July 14, 1749. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Description The eclipse was visible in much of South America except for Guyaranquil, New Granada (now in Ecuador) and around it and the southern tip, Florida (then also as Spanish Florida) and the Caribbean, the Atlantic, much of Africa except for the Ottoman lands of a part of Tunis including Philippeville (now Bizerte) and Carthage, Cyrenaica, Egypt and East Nubia as well as the Somali Peninsula and much of Spain and Portugal except for the Pyrenees. It was also visible in a small part of the Indian Oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of February 9, 1766
A total solar eclipse occurred on Sunday, February 9, 1766. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Observations File:Solar eclipse 1766Feb09-Comte d'Artois.png Related eclipses It is a part of solar Saros 117 Saros cycle The saros () is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon. ....

Solar Eclipse Of June 24, 1778
A total solar eclipse occurred on June 24, 1778. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The total eclipse was visible in a path across Mexico, southeastern United States, and ended across northern Africa. Observations This was the first total solar eclipse recorded in the United States. The track passed from Lower California to New England. According to Thomas Jefferson, the eclipse was clouded out in Virginia. General George Rogers Clark and his men observed the eclipse as they passed over the Falls of the Ohio on their way to take Kaskaskia during the Illinois Campaign T ...

Solar Eclipse Of October 27, 1780
A total solar eclipse occurred on October 27, 1780. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Observations During the American Revolutionary War, the first American solar eclipse expedition was organized and sent out from Harvard College in Massachusetts. A special immunity agreement was negotiated with the British to allow the scientists to work unharmed. The Harvard expedition, after all their efforts, missed the eclipse because they chose a site outside the path of totality. Modern analysis of this embarrassing incident for embryonic American science blames Samuel Williams for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of September 16, 1792
An annular solar eclipse occurred on September 16, 1792. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Description The eclipse was visible in a small part of Northeast Brazil including Recife, almost the whole of Africa with the exception of the southernmost area, southern Europe, and parts of Asia with much of the west of the Middle East, South India, Southeast Asia and less than half of its southeast islands as well as parts of the Atlantic, the Indian Ocean and the coast of New Holland, Australia.

18th-century Solar Eclipses
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events. To historians who expan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
