Each decan consisted of ten days, so they would keep track of which star rose with the sun, and then ten days later, a new decan would begin. Not only were these stars useful for timekeeping, they were also believed to have been powerful deities as well, according to the Egyptians. They viewed the planets as having great power, and thought the same thing with the stars. These decans were also very effective in proving that a day consists of twenty four hours, which is split evenly between day and night. The Egyptians’ method of timekeeping was extremely reliable and accurate.
Edwin Hubble one of the more well known astronomers of his era, was able to provide the understanding and knowledge capable for furthering the knowledge of the universe. Hired in 1919 to work at the Mount Wilson Observatory as one of the more junior astronomers, with the more important questions resulting in along the same lines of 'what 's the nature of the surrounding nebulae. ' It should be noted that Edwin Hubble was able to actually answer this question, explaining that these nebulae or rather some of them were not in the Milky Way galaxy. With the method he used to measure the distances he was able to prove that the universe was actually expanding. Building off the research and discoveries from Harlow Shapley who had measured the distance of the Milky Way, Hubble was able to determine the distance to the nearby Andromeda galaxy.
The Ancient Mayans lived in the Yucatán around 2600 B.C.E. Today, this area is known as southern Mexico; Guatemala, northern Belize and western Honduras. The Mayans, primarily focused on the Sun as they relied on it for many reasons. However, they also focused on the Moon, the stars and the planets. Everything in the celestial hemisphere was monitored and recorded by the Mayans; they were considered to be astute astronomers.
My topic is about “John F. Kennedy’s Moon Speech”. The speech was given by the John F. Kennedy at May 25 1961 after the astronomy landed on the moon and returned to the Earth safely. This event is one of the most important events in the astronomic history. It was the first time that people truly landed and walked on the moon. This landing event did have a great influence in the history and politics.
It seems common knowledge that in 1961 the United States of America became the first country to put a man on the moon. On the other hand, not everyone fully understands what an enormous accomplishment this was and how it has greatly impacted society today. The Apollo 11 mission not only proved that the United States was the leading super power in the world, but it also helped provide much needed nationalism, increase in support for science, math, and technology, and allowed for the technological advancements that around around today. For this reason, a monument is proposed to memorialize the numerous accomplishments made by the Apollo 11 mission. This monument will not only educate the public about the effects of the moon landing but also the
Many people could be given credit for finding Neptune but John Couch Adams and Urbain-Jean-Joseph Le Verrier got most all of the credit. It was the first planet to be discovered by telescope but the first planet to be found by people specifically searching for one. It was launched in August 1977 the spacecraft went to Jupiter in 1979 and Saturn in 1981. After it went there it was programmed to go to Uranus in 1979 and last Neptune in 1989. The data and 10,000 pictures it took increased the knowledge of Neptune majorly.
Another astronomer Al-Sulfi found one thousand plus uses for the astrolabe. Some of the areas he found new uses for were astronomy, navigation, and surveying. The astrolabe was also used to find out how far earth was in the sun. The first time they did it it was off but then they innovated it and it came out more accurate. They were only eight miles off.
This is evident even today when his laws determine the outcome of a space station being launched into planetary orbit. Though Einstein’s theory of relativity has been responsible for serious scientific and technological advancement, Einstein initially proposed his theories from his own thought experiments, considering previous theories and reaching contradictions or abnormalities. An example of this is, “what would happen here on Earth, if the sun suddenly disappeared?”. If Earth broke out of it’s gravitational orbit, and took a different trajectory, before the sun’s rays could reach the observers on Earth (8 minutes), then essentially gravity travels faster than the speed of light. A contradiction.
John Herschel discovered Uranus in 1781 while searching for double stars. There had been recent developments in Newton’s mathematics that would allow astronomers to calculate the orbits of celestial bodies and he wanted to learn more about the physical nature of stars. When he first saw Uranus through his seven-foot reflecting telescope, he thought it was a comet. Very few astronomers believed there was a possibility of more planets, other than the five they knew of, the moon, and the sun. It wasn’t until a Russian astronomer calculated the orbit of the “comet”, following a slow moving path, that it was determined that it was a planet.
Australian Aboriginals or the indigenous Australians are believed to have been one of the world’s first astronomers. Studying many astronomical objects such as the sun, moon, planets, stars, and even the Milky Way! Aboriginals also use the sky as a calendar. Northern Australian aborigines used a more complex calendar with six seasons and some mark the seasons by which stars are more visible during those months. Some stories say that the heliacal rising told the aboriginals when it is time to move on and look for food elsewhere.
As he was studying, he began to disagree with it. He used science, math, and a yardstick to study the Universe for himself. After measuring the altitude and angles of stars and planets, he was able to claim that the planets revolved around the sun and that only the moon orbited around Earth. According to the document, “Copernicus wrote a short report called the Little Commentary, that explained his heliocentric theory (8).” This report was only shared with a couple of his friends. After 20 years, Copernicus agreed to share his new discovery with the world by publishing a book called On the Revolutions of the Celestial Spheres about his discoveries.
