The name Dakosaurus means "tearing lizard". The Dakosaurus ' average length is 4-5 meters long which, in American length system, is about 13-16 feet long, and weighed about 18,000 lbs. It 's Latin name is "Dakosaurus Andiniensis". The person who named it was Friedrich August Von Quenstedt in 1856.
William Herschel was the first to notice this odd object and was curious to find out more. This odd object, Uranus, was the first planet in recorded history to be discovered. The discovery of Uranus was just the beginning of William Herschel’s discoveries. He left his work with music and became
The young astronomer earned a permanent place in the history of science when he discovered the planet Pluto on February 18, 1930. Pluto orbit lies 3 billion miles from the sun; it takes Pluto two and a half earthly centuries to complete a single orbit around the sun. Seen from Pluto, the sun appears merely as one bright star among many. Pluto 's moon, Charon, is nearly half the size of the planet itself and orbits Pluto once in every 6.4 Earth days. From Pluto, Charon appears eight times larger than our moon appears from the Earth.
Herschel, an amateur astronomer, was not seeking to discover a new planet. Besides general curiosity, his motivations appear to be money, prestige, and power. He was looking for double stars as a way to measure stellar parallax. He had built his own 7ft reflector telescope which he moved to his house in Bath. There he discovered what would later be called Uranus.
The foundation for modern astronomy was laid by this discovery. The first person to realize that the moon revolves around the earth was Aristarchus [1]. Tracking the position of the Moon in the sky over time, allowed him to estimate its size. His theory was debated in the scientific community for centuries after he died. Aristarchus was correct about both theories, according to modern science.
William Herschel found Uranus on March 13, 1781. This was a big deal to him and his career. As stated in a document I found “Uranus was important for Herschel because its discovery was a passport to royal patronage, a pension of 200 pounds per annum, and a substantial support for his investigations of the construction of the sidereal heavens”. Herschel used a telescope which no one found would really work and the thought of one working was unimaginable. Some small ones were in use by scientist but Herschel wanted to develop a more powerful one that everyone would know would work better.
Bias in Observations and the Discover of Uranus There were a number of assumptions and a degree of bias that influenced the initial conclusions made when William Herschel discovered the planet Uranus in 1781. His passion for astronomy led him to make observations as he studied the night sky. With a series of measurements, Herschel observed that there was an object in the sky getting larger and approaching the earth. He believed that it was a comet… an idea that encouraged excitement.
While the goal of most astronomers was to chart the positions of planets and stars in the sky using mathematics, Herschel, however, was interested in the evolution of stars, and not their positions. When he discovered Uranus in 1781, he thought it was merely a comet. He contacted other astronomers about the new discovery. A month later astronomer Nevil Maskelyne suggested that
Whereas earlier astronomers had been content to observe the positions of planets and the Moon at certain important points of their orbits. Tycho and his cast of
Pluto is also called a plutoid, meaning it orbits the sun but is farther from it then Neptune. Since Pluto was discovered on February 18, 1930 by Clyde W. Tombaugh,
Controversy over Pluto Pluto was once considered one of the nine major planets in our solar system until 2006. The reason for this was in 2003, when an astronomer found another object in close proximity to Pluto that appeared to be larger. Based on Pluto’s size and location it was stripped of its status and was then classified as a dwarf planet. I was 11 when this event occurred. It was one of those major events in history that would result in textbooks being rewritten.
Aristarchus of Samos was born 310 bce on the Greek island of Samos, and died 230 bce. It is said that his work was lost through out time, but his reserved work was an essential key to the study of science. He was a Greek astronomer and mathematician who became popular for his theories about our solar system. Out of math, he was the first to state that the sun, not the earth, was at the center of our solar system. However, everybody thought that hi was insane for thinking that, but he was on the correct.
Pluto is not a planet because it doesn’t have all the criteria needed to be defined as a planet. According to Snowbrains.com, a planet needs to orbit the sun, have enough gravitational pull itself into a spherical shape, and clear its neighborhood by being a dominant source of gravity. The text from Discoveryeducation.com states, “In 2005, space probes identified a Kuiper Belt object named Eris that is more massive than Pluto. Eris was classified as a dwarf planet within the Kuiper Belt.” In an article from Theatlantic.com, the author stated, “Upon its discovery, in 1930, scientists trumpeted that Pluto was about as large as Earth.
The rings were first observed by the Italian astronomer Galileo Galilei in 1610 with the help of early less powerful telescope. His telescope wasn 't that good (low resolution) as compare to today’s telescope, though, he able to observe "blobs" on both side of Saturn, which he thought were moons of Saturn. Later in 1656 a Dutch astronomer Christiaan Huygens able to correctly identified the "blobs" as rings around Saturn. They have allured and perplexed astronomers since they were discovered 400 years ago. Many mathematicians have study the distribution of particles of ice and rock throughout the rings and believe that they are attributes of catastrophic collisions over time.
One of the most well known astronomers of all time is Nicolaus Copernicus. He was known to think outside of the box and dreamt of bigger things in life. Copernicus did not see the world and its surroundings like everyone else did. Having such a brilliant mind helped him discover an important theory. Many scientists and astronomers would never see our solar system the same.
