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. It was also during this time that Hubble was able to discover that the universe was …show more content…
With all the discoveries Hubble would not allow what he had already discovered to be all that he had worked for. It was in this matter that Hubble was able to work with the information provided by Vesto Slipher. Through the careful mesurement of the Doppler shift of other galaxies, he was able to determine that there was a few galaxies that were moving at very high speeds heading towards the Milky Way. It was also through measuring the Doppler shift that Hubble was able to prove through a paper that he wrote in 1929 explaining that, and proving the universe was expanding. It was also through the Doppler shift and measuring the rate of expansion of the known universe that the possibility of determining the age of the universe is also possible. With everything that Edwin Hubble was able to accomplish in his life, Hubble was able to provide scientists and future generations with further wonder at the universe. With the launch of the Hubble space telescope, his name lives on to this day and further providing him with a legacy that will be
This will lead to his discovery of the three laws of planetary motion that explained how the planets moved and why they looked how they do in the sky. 4) Galileo Galilei was an astronomer whose studies would reveal the importance to astronomy not only of observation and mathematics but also of physics. His self-consciousness about technique, argument, and evidence would make him one of the first investigators of nature to approach his work in the same way as a modern scientist. 5) Francis Bacon was one of science’s greatest propagandists, and he inspired an entire generation with his vision of what scientific inquiry could do for humanity.
I researched about William Herschel, who was a conductor, organist, composer and music teacher. William Herschel knew the stars well and was always curious as to what was beyond the Earth. He had built himself a homemade telescope and enjoyed viewing the stars from it. As he was observing the stars one night he noticed an object that he could not clarify what it was. Other astronomers had seen this object, but never really observed how different it was.
In the novel, Death By Black Hole, Neil DeGrasse Tyson proves that the common assumption that the color of our solar system’s sun is yellow, is, in fact, an incorrect belief. Many people think that the sun is yellow because, “Near sunset … the blue light from the sun’s spectrum, lost to the twilight sky, leaves behind a yellow-orange-red hue…”(Tyson 293).This shows why this common misconception is not an easy thing to spot and is understandable why most people incorrectly assume the color of the sun. The actual color of the sun is proven by the fact that, “ if the sun were yellow… then white stuff would reflect this light and appear yellow…”(Tyson 293). If the sun was actually yellow then the colors we see around us would have been changed
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.
Clyde Tombaugh Clyde Tombaugh was a major contributor in the field of astronomy. Born in Streator, Illinois, on February 4, 1906, His family moved to Burdett, Kansas in 1922. A hail storm ruined the farm’s crops, while also ruining Tombaugh’s chances of going to college at young age. His interest in astronomy started when an uncle showed him the night sky through a telescopes. He built telescopes by himself starting in 1926, after he graduated from high school.
During the Renaissance, astronomy advanced and excelled rapidly thanks to many significant astronomers. Before the Copernican theory was established, Aristotle had a cosmological theory that stated that the Earth was the center of cosmos,
Wernher Von Braun “That’s one small step for man, one giant leap for mankind.” These were Neil Armstrong's words as he took his first step on the moon. While his achievements will be passed down through history, what we forget to give credit to is the person that allowed them to get there in the first place. A genius. He was a brilliant mind that developed technology that had only been dreamed of before.
The invention of the Voyager 1 has had the biggest impact on humanity. Voyager 1 explores planets to provide useful and groundbreaking information, allows astronomers to make advancements in their field, and collects a lot of data.
This points directly to the importance of the scientific method and how Shapley was able to make such progress and observations because of past efforts. Shapley’s identification of the usefulness of Cepheid variables as distance indicators was a major point that he was correct about and this provided an immense contribution to the field of astronomy. On the other hand, Curtis was able to correctly identify that spiral nebulae are external galaxies and provided valid scientific evidence for the first time in history. As a result, his efforts exemplified that hypotheses become stronger and more valid once evidence is attained to support that observation made by a
For over 200 thousand of years civilizations have looked upon the night sky attempting to comprehend the endless sea of bright lights that stood before them .However, with the recent technological and astronomical advancements, scientist have been able analysis, and prove some of the world's greatest mysteries (ranging from “sustaining life on other planets”, to “what may lay beyond our known universe”). This new information has greatly impacted society, by allowing everyday civilians to gain a greater understanding of the vast world around them. However none of this would have been possible, if not for the work of Johannes Kepler, pioneering the way for many of great astronomy related discoveries. Kepler is often considered the father of modern
Harlow Shapley was a very well established man who had made significant discoveries in the world of science. It was Shapley that had found out that the sun was not, in fact, the center of the universe but rather 30,000 light years away, an important piece of information embedded within us from as soon as we start learning about our solar system. But, before going down as one of the most historic men in science, he had lived a life as interesting as the concepts he had explored. Born in Nashville, Missouri on November 2nd of 1885, Harlow Shapley was the son of a locally known farmer, as well as school teacher, Willis Shapley, and his mother, Sarah Stowell. Harlow, attending a local schoolhouse, received a basic fifth-grade level of education.
Geogre Lemaitre made what is now known as one of the greatest discoveries in modern cosmology: that the universe is expanding. He proposed that the universe began in a “single quantum” which is now known as the Big Bang. The first hints that the universe was expanding began whn Einstein published his work on his theory of relativity. To his surprise, Einstein’s work showed that the universe was either expanding or contracting. Since there was no evidence to prove this, Einstein added his famous cosmological constant, which provided a static universe which has always and always will be the same size.
Copernicus developed the heliocentric theory which claimed that the earth revolved around the sun. This immediately challenged the authorities who believed the opposite. Galileo furthered Copernicus’ argument and promoted that the Bible, that God
Before modern technology allowed astronomers to determine the exact distances between the Earth and other objects in the solar system, they had to rely on alternative methods to make these measurements. Two scientists who made some of these early measurements were Johannes Kepler and Giovanni Cassini. Kepler used the time of a planet’s orbit to determine the relative distance between the Earth and other objects, while Cassini used the parallax method to estimate distances. Johannes Kepler was born in 1571 in a small town called Weil der Swadt in Swabia, Germany and is well known for discovering the three laws of planetary motion. In 1589 he began his college level education in Tubingen at the Protestant university there.
Others recognized patterns in the ways the objects moved. Thus, astronomy was born. Around 600 B.C. it was accepted that the Earth was not a flat object through the insight of Greek philosophers from looking at the round shadow that the Earth cast on the Moon during lunar eclipses and how the stars seemed to move as one approaches the North Pole. (Larsen, 37). Eudoxus was philosopher known for the idea of a geocentric
