Edwin Hubble Research Paper

“classified Hubble as a Cassegrain reflector, who was among the first to suggest a basic optical design.”1 The Hubble space telescope was launched and deployed in April of 1990, which “marked the most significant advance in astronomy since Galileo's telescope. Thanks to four servicing missions and more than 25 years of operation, the view of the universe and humanity's place within it has never been the same.” 2 In describing how

Galileo might be the most famous person in the development of astronomy. He is famous, not only because of the amazing work he did to advance Copernican theory of heliocentrism, but also because of the controversy that surrounded him. Using new methods and instruments, he provided compelling new evidence to support Copernican theory. He also contributed to the development of theories of physics that could account for the movements of bodies in new terms. His observations of the movements of objects in the heavens required different explanations than the old ideas about the heavens. It required him, and others, to begin to understand the reasons to explain these new observations. His efforts to publicize his findings was met by

Whether it was spending ÅÇrigid nights beneath the open observatory dome photographing nebulae¡¦(Parshall et al, 1998, p.PG) or forever challenging the concepts that he deemed unsubstantial, Hubble made it his lifelong ambition to ascertain as much information about the universeÃÔ vastness as he possibly could. Of all the monumental discoveries that were credited to HubbleÃÔ perseverance, one of the most important concerned the issue of receding galaxies. By all appearances, Hubble had stumbled onto the fact that ¡¦the cosmos was expanding, flying apart as if it has once been highly concentrated¡¦(Parshall et al, 1998 p.PG). Little did he know at the time, but his discovery would come to represent the big bang theory that has evolved as such a well-known concept within the worldÃÔ contemporary scientific society. Hubble was a US astronomer who studied extragalactic nebulae and demonstrated them to be galaxies like our own. He found the first evidence for the expansion of the Universe, in accordance with the cosmological theories of George Lema and Willem de Sitter, and his work led to an enormous expansion of our perception of the size of the Universe.

What is one of the most amazing astronomy inventions, that has changed the way we look at space forever? This invention is the Hubble space telescope. The telescope was launched into space in 1990 and has found many amazing discoveries. If the hubble wasn’t created astronomers would not have near as good of understanding of astronomical bodies like Dark energy, we wouldn’t have found what is believed to be the most distant object ever seen in the universe with a distance of 13.2 billion light years away, and we would not have a good . There is no doubt the hubble telescope is a very incredible invention and has been very helpful to the astronomy, and will continue to be a huge resource to discoveries of the universe.

Edwin Hubble was an important contributor to the Big Bang Theory. Edwin Hubble received his PhD in Astronomy at Chicago University. After college, he became the lead researcher in the field of astrophysics at Mount Wilson in California. He has done many things to help prove that the Big Bang Theory did in fact happen.

2. Explain how Edwin Hubble used Cepheid variables to change our view of the structure of the universe.

The Accomplishments of Edwin hubble Have you ever wanted to study the stars and the universe? Well, Edwin Hubble did ,Edwin Hubble is a famous astronomer who played a crucial role in the field of extragalactic astronomy. He is known as the most Important observational Cosmologist the 20th century. He found out that the universe goes beyond the milky way and that the universe is expanding. This essay consists of the life, childhood, and accomplishments of Edwin Hubble (Wikipedia)

He published the first textbook of Copernican astronomy. (Johannes Kepler (German astronomer).Kepler also provided an account of

The Hubble costs about 2.5 billion dollars to make. Also it has 6 cameras and sensors. It was launched in the honor of Edwin Hubble (also why the telescope was named after Edwin). As the telescope goes around in orbit with a light spectrum from the ultraviolet to near infrared it is able to take some very incredibly close and clear images. The telescope uses a digital camera to capture all of the great images and uses radio waves to send the pictures through air back to the Earth so we all are able to see what great things are happening outside of the Earth. With all of the information we get from the telescope we are able to stars being born and stars die. We are able to see galaxies that trillion miles away. It was able to see a comet pieces crash into gases above Jupiter. Also, we have been to discover moons that are around pluto that have never been able to see before. Additionally, we are able to understand how planets and galaxies form. We have so much information and have discovered so many new things from the Hubble Space

The Hubble telescope has found over 400 habitable planets in the known universe ( Space.com Staff. Web). The Hubble telescope has discovered that in almost any galaxy that has a star cluster at its center, will have a supermassive black hole ( Space.com Staff. Web). The Hubble discovered that dark energy takes up 74% of the combined mass energy in the universe and is the key to why the universe is expanding at a never ending rate ( Space.com Staff.

“William Herschel was a man of wide interests outside of music, and astronomy was one of them”. From 1767 forward he began to observe the night-sky, but the telescopes available back then where small with limit potential, so in 1773 he began to develop his own telescopes. With the help of his brother Alexander and sister Caroline, he began to build the best telescopes in the world.

Edwin created Hubble’s Law, which supported the Big Bang Theory. Hubble also figured out that the Milky Way is not the only celestial body in the universe. “Hubble added integral knowledge to the field of astronomy, including the discovery of other galaxies and proof that the universe is constantly expanding” (Contemporary Heroes and Heroines, 2000). Hubble innovated in his field by changing the perspective of the Universe, and impacted society by making the world so much bigger. Hubble’s discoveries inspired multiple people to join the field of astronomy, and to remain open to new situations. Whenever somebody is able to do this well, they are bound to do great

John Powell Hubble was Edwin Hubble’s father. Edwin and his father contrasted in views of the future. John wanted Edwin to get a degree in law, and that is why Edwin studied law in college. However, John passed away in 1912, and it was because of this that Edwin returned to America (he had been at Queen’s College in England studying law) to start a career in astronomy. His father did not want Edwin to pursue astronomy because he “wouldn’t have let him go through school if he was going to be a thing so outlandish” (Christianson 40). Nevertheless, Edwin still studied astronomy; it was just after his father

As Hubble age, he was unable to use the telescope any more. He didn’t have the strength or energy to stay in the cage for long periods of time. So, he sent Sandage to carry out tasks for him. Everyday Sandage would be given coordinates or jobs by Hubble. When Sandage was done recording he data of his work, he would go back to Hubble and give him the results (Overbye 22). This shows how devoted he was to his research, even if he was unable to handle the job due to old age he compromised. All of Hubble’s work and Sandage work was done on the 100-in telescope, yet Hubble was still able to find the Andromeda Nebulae’s distance for the Milky Way and study red shifts. While the 200-in. telescope was being built, Hubble asked if he could use the telescope for half of its available time. This shows his devotion because he wanted to use the telescope in order to further enhance his research (17).

As stated on nasa.gov, “Hubble has made more than 1.2 million observations since it’s missions began in 1990.” Hubble has also expanded astronomers knowledge about the universe and space as a whole. The most famous observation made by this telescope was that of galaxies beyond our own, Milky Way, and discovering that the universe is much larger than further predicted. Before this telescope, ground based telescopes could only see into our galaxy and could not reach any further. Therefore, it was thought that the Milky Way was the only galaxy included in space and the universe. Due to the fact, Hubble’s telescope, expands and allows for the study across a wider light spectrum, astronomers can see beyond further predicted. Another famous observation, studied by astronomers was that of the study of uncharted territories of the cosmos. As proposed on hubblesite.org, “It became increasingly clear to astronomers that Earth’s atmosphere distorted starlight, which made it difficult to obtain razor-sharp views of celestial objects. The idea of placing a telescope in space, above Earth’s turbulent air, had been kicked around for several years. But scientists pondered how to transport a telescope into space.” That was until, Hubble’s creation that displayed imagery of the cosmos. Once again it had accomplished a feat that had troubled ground based telescopes. In
