Essay about Edwin Hubble Biography

The telescope would become the indispensable instrument for investigations of the cosmos. Bigger and better telescopes were built all over the world. Planets, stars, and nebulae which could not be seen by the naked eye were now being routinely noted and logged. Such is the case with the fantastic discoveries for which the Hubble Space Telescope has been responsible during the twentieth century. Had it not been for the creation of such a monumental piece of scientific machinery, the worlds not have

The telescope is very massive it is actually the size of a school bus and weighs about as much as much as 2 grown elephants. The telescope orbits the Earth about 340 miles above.The telescope can travel at about 5 miles per second, this is very cool because that would mean the telescope travels at 18,000 miles per hour. The telescope was supposed to be launched into outer space in the year 1985, but the space shuttle challenger exploded and the launch was postponed while Nasa tried to figure out how to safely resume the launch. In the year 1990 the telescope was launched. The telescope uses digital cameras to get pictures and information and send them through radio waves. The parts of this incredible telescope include, a wide field camera which is a camera that “has higher resolution or ability to distinguish details and a larger field of view or area.”(http://hubblesite.org/) The cosmic origins spectrograph “break light into colors and measure the intensity of each color, revealing information about the object emitting the light.”(http://hubblesite.org/) The advanced camera for surveys is a camera that “ sees in wavelengths from the far ultraviolet to visible light, making it capable of studying some of the earliest activity in the universe.”(http://hubblesite.org/) There are many other parts to the Hubble telescope and all of the parts that were needed for this telescope were put together and created this amazing

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.

Galileo was an Italian mathematician and astronomer who developed an improved telescope. He made observations the undermined established understandings of the cosmos. His discovery of Jupiter and many new stars, suggested a cosmos far larger than the finite universe of traditional astronomy. He published his remarkable findings in a book titled The Starry Messenger. (Ways of the World, 557-559)

Hamilton obtained scholarships due to his notable writing skills (Columbia Press). As a result, he was admitted to the bar in New York where he majored in Law (Brookshier). In addition, he worked for a mercantile firm of Baekham and Chiger (Columbia Press). Then, he served as a captain in New York Artillery Company whereas he was discovered by George Washington, as a result he became colonel to Washington’s staff (Brookshier).

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

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.

Since the University didn’t officially offer a formal course in astronomy at the time, Hubble decided to apply for a job as an assistant at Yerkes observatory. It was while he was at Yerkes observatory that Edwin discover that there were other galaxies outside of the Milky Way, even though at this time other scientists refuted his claim. (Datnow,

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

He originally wanted to study natural science, but he was unable to because he did not have the proper funding. A major in medicine was funded by the government. Afterwards, he was offered a full scholarship at the Friedrich Wilhelm Medical Institute in Berlin as long as after he graduated he served as an army doctor for eight years. In 1843, after graduating from medical schools he would work in laboratories working on different experiments as well as serving as an army surgeon.

The Hubble Space Telescope is one of the most amazing machines in orbit right now. In 1946, an astrophysicist named Dr. Lyman Spitzer proposed that a telescope in space would reveal better and clearer images that are even far from earth than any ground telescope. This idea was very extravagant because no one had yet launched a rocket into outer space. As the US space program excelled quickly over the early years, Spitzer lobbied NASA and Congress to develop a space telescope. In 1975, the European Space Agency and NASA began to develop the telescope that would change astronomy for ever. In 1977, Congress approved funding for the development of the space telescope and NASA named Lockheed Martin Aerospace Company as the prime contractor

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

     Science is and has become a necessity to know just to keep up with the tremendous advancements of today and tomorrow. Basic things, such as how the universe was suspected to be started or who Ptolemy and Galileo were and what they did are just things that need to be known to fully understand what is happening in the world around you. These things are what you need to know, if you’re a scientists, to a grocery shop bagger.
