As the Hubble telescope’s life comes to a historic end, we look back at all it has done for the scientific community. The Hubble has helped scientists make many new discoveries about our universe. Galileo Galilei and Edwin Hubble were huge contributes to the astronomical community, therefore a major help in transforming the first telescope into something as amazing as the Hubble. The first telescope was perfected by Galileo in 1609, and around four hundred years later the Hubble was launched into space. Since then the Hubble has shown scientists many new discoveries about space that they would have never been able to figure out without the Hubble’s help. Since April 1990 the Hubble telescope has been greatly appreciated by the scientific community because of everything it has done. However, the Hubble has faced many problems along its way as well.
Edwin Powell Hubble: Great Astronomer of the 19th Century Twinkle, twinkle little star, How I wonder what you are! Up above the world so high, 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).
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 to oversee its construction. In 1983, the telescope was finished and was named after Edwin Hubble, an American astronomer whose observations of variable stars in distant galaxies confirmed that the universe was expanding and gave support to the "Big Bang" theory.
Centuries ago, people gazed into the night sky wondering what it was that they were looking at. When astronomers first started to study the night sky, like Galileo, Copernicus and even modern day astronomers, they all shared one goal, and that was to see further than anyone has ever before. The invention of the Hubble Space Telescope changed the study of astronomy forever. Astronomers were seeing and learning more in just days of the launch of the telescope than past astronomers had in their lifetimes. The Hubble Space Telescope is the most technologically advanced telescope to enter space. Its advanced technology has made it possible to obtain countless amounts of data about space and open many doors in the exploration of space. Its accuracy has and still is proving/debunking the myths of space.

...tence of the Hubble Space Telescope is the many discoveries it has made. As well as discovering that Pluto is not a planet, Hubble also discovered evidence that other planets do not only orbit the sun, but other stars as well. Hubble was also the founder of dark energy, meaning that the expansion of the universe accelerates because of this force. Another amazing discovery made by Hubble is the actual age of the universe. The original age of the universe was thought to be 20 to 30 billion years until Hubble revealed the age to be about 13 to 14 billion years old.
Novice stargazers are often disappointed because they cannot see the rainbow of colors that appear in celestial photos taken by the Hubble Telescope. This is because the human eye’s color sensors do not function well under low light levels.
Carl Sagan is known as one of the most famous scientists of all time. He revolutionized how the world looked at space and the search for intelligent life beyond our planet. The author of many books, he is most known for Contact (which was adapted into a movie) and for the PBS documentary Cosmos. As one of America's most famous astronomers and science-fiction writers, Carl Sagan turned a life of science into one of the most critically successful scientific careers of the 20th century.
