Like a diamond in the sky (Gardner 98).

Stars are a marvelous wonder to many people, that is why some people spend most of their lives wondering what is "above the world so high" (Gardner 98). These people study and map the little twinkling stars in order to get a better meaning of them; they are astronomers. Great astronomers like Edwin Hubble, Immanuel Kant, and William Huggins, never stopped valuing the beauty of the stars. While they developed great astronomical principals. One astronomer who fits this mold most is, Edwin Powell Hubble. Wondering about what was out in the universe led to the construction of the 200-in reflector telescope, the most high-powered of its day. Using this high-powered telescope he went on to prove that there were other galaxies beside the Milky Way and was able to formulate Hubble's law, which linked the distance of galaxies to their speed. Through his work, Edwin Hubble impacted the scientific world in the twentieth century because of devotion to research, curiosity about the universe, and expertise at mapping galaxies.

Unable to complete his any tasks on his own, Hubble hired an assistant. He hired Sandage. Sandage would work with Hubble and learn techniques that Hubble used to hopefully do research of his own in the future. Hubble taught Sandage how to classify galaxies so he could continue Hubble's work. 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).

Hubble's devotion was mental and also physical. Hubble worked at Mount Wilson for most of his career. Here, "he spent hundreds of bone-numbing hours in the observer's cage at Mount Wilson telescope. Anyone who has spent time in 'the cage' knows what an extraordinary effort of will it can demand: total concentration, and an ability to suppress shivers in the constant chill, lest you vibrate the telescope." (Smoot 42).

Edwin Hubble's curiosity about the universe started at youth and has grown. Without this, he would have no desire to study the stars or galaxies. Hubble's interest in astronomy at the age of eight. On his eighth birthday party he spent the night with his grandfather star gazing (Freidman 16). When he was twelve years old he would a
