“The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.”
-Edwin Hubble

Edwin Hubble was an American astronomer. Hubble played a crucial role in establishing the fields of astronomy and cosmology. Hubble proved that many objects thought to be nebulas were galaxies beyond the Milky Way. Edwin Hubble did not only just say we have other galaxies, but our universe was expanding. Edwin Hubble helped revolutionize astronomy and how we classify galaxies, and it is called the Hubble Classification Scheme.
Astronomers believed there was only one galaxy in the universe, not knowing they classified them as nebulas. That they thought inside the Milky Way …show more content…

They both worked together on studying galaxies and their distances. Humason measured the spectral shifts of the galaxies and Hubble was tasked with determining their distances. Hubble concluded that if one galaxy is twice as far away from another galaxy, the galaxy’s redshift is twice as large. Hubble then discovers that the universe is not static. The relation between redshift helped Hubble come up with the theory that the universe is expanding. He came to the conclusion that the universe is expanding by observing the redshift of light from distant galaxies.
Many people came together to put this theory together that the universe is expanding, Albert Einstein and his development of general relativity and Willem de Sitter who developed theoretical models of the universe. Hubble helped these observations with mathematical form to put the evidence that the universe is expanding. People were unsure with the universe is expanding theory, they thought it was far off. “If what the great telescope apparently sees is right, Dr. Hubble said, the nebulae may be endlessly distributed, on and on, virtually to …show more content…

Edwin Hubble’s classification Scheme helped lay the foundation for understanding galactic evolution and the formation of the universe. The classification has proven to be a useful tool in understanding the diversity and evolution of galaxies. Hubble provided a standard way of categorizing galaxies, making it easier for astronomer to compare their observation. The Hubble classification scheme was a major contribution to our understanding of the universe. It helps people classify their observation of the universe and study the galaxies easier. The Hubble classification helps with future research due to the fact that classification of the galaxies is much easier to

    For instance, Roman astronomer; Ptolemy developed the “Geocentric” theory of the universe, in which the Earth was believed to be in the center of the universe. (Doc. C) Furthermore, polish astronomer; Nicolaus Copernicus, who relied on mathematics and observations created a different understanding of the universe, called the “Heliocentric” universe. Heliocentric meaning “sun-centered,” in other words meaning that the sun is believed to be at the center of the universe unlike the Geocentric theory. (Doc. C)

    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.

    Such as the way people thought the layout of the universe was. There were two different ways it was assumed to look either in the favor of Ptolemy or Copernicus. “He developed a theory of the universe that was adopted by most scholars” (Doc C). The difference in scientific information from the Renaissance to the Middle Ages verified how statistics has developed throughout time. Roman astronomer, Ptolemy, developed a geocentric (Earth-centered) model of the universe which was believed to be true by most scholars (Doc C).

    Other scientists like Nicolas Copernicus believed in the Heliocentric Theory. At first, it didn’t explain how the planets orbits the way they did and was very hesitant to share it with others. In 1601, another scientist named Johannes Kepler proved that Copernicus idea was correct. They show that the planets rotate around the sun. Another method Copernicus, Kepler, and Galileo developed was called the Scientific Method.

    One astronomer, Edwin Hubble, found a variable star located inside Andromeda’s spiral nebula and measured its’ period. By using Leavitt’s period-luminosity relationship, Hubble found the luminosity of that variable star. By knowing the star’s luminosity and measuring its’ apparent brightness, Hubble was able to calculate the distance from Earth to Andromeda. He calculated a distance of over 900,000 light years, which exceeded the distance across the Milky Way (100,000 light years). His findings proved that Andromeda was a galaxy in its’ own right, and therefore it is possible that there are other galaxies out in the

    But when the twentieth century was at the gates of new and historical events, that began to change. New discoveries shook the old certainties and paved away for questions about "where the universe came from?". One observation transformed our ideas about the true scale of the universe. It began with a mystery in the sky. By the early part of the twentieth century, it was well known that our solar system lay within a galaxy, the milky way.

    Have you ever thought about what really happens in space? Well the Hubble Telescope is an invention that really got a closer look at what is really seen. The Hubble Space Telescope is a telescope that captured images of baby stars and had also discovered many things that happened in space. Because of this telescope, scientists are thankful that questions they may have had in the past were answered due to this amazing invention. The invention that had the biggest impact on humanity was the Hubble Space Telescope.

    Did you know that Annie Cannon was able to classify around a thousand stars a day during the peak of her career? This paper will be focusing on the life, career, and legacy of Annie Jump Cannon. Annie Jump Cannon was hired by Edward Pickering, and she worked as “Pickering’s assistant at the Harvard College Observatory” (1). After that, she was credited with coming up with an easy system that divided the stars into seven spectral classes. The spectral classes were as follows: O, B, A, F, G, K, M. Annie Jump Cannon’s career ended after forty years, but her work paved the way for women in the scientific community and continues to inspire fellow female scientists.

Galileo made many discoveries with his telescope that were significant to science during the Renaissance. To view the solar system, Galileo made a telescope on his own. He had heard of the invention from a Dutch eyeglass maker, and improved his design.
