Doran 1John DoranMr. JurgensEnglishApril 4, 2014The Hubble Space TelescopeCenturies ago, people looked at the night sky and wondered what they were looking at. When astronomers first began studying the night sky, such as Galileo, Copernicus, and even modern astronomers, they all shared one goal: to see further than anyone had ever done before. The invention of the Hubble Space Telescope changed the study of astronomy forever. Astronomers have seen and learned more in just a few days since the telescope's launch than past astronomers could have done in a lifetime. 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 space exploration. Its precision has and continues to prove/debunk the myths of space. Once NASA was granted the right to begin building the Hubble Space Telescope, or paraphrased as HST, it cost $1.5 billion to build. The length of this huge piece of technology is 43.5 feet (13.2 m). The HST has a diameter of 4.2 m which allows it to store hard drives, processors and other fragile technical parts inside the telescope. With its metal base, solar panels, mirrors etc. that protect the telescope's fragile interior from floating space debris, the HST weighs 24,500 pounds ("The Telescope"). Doran 2The most technologically advanced part of the telescope is its mirrors and optical capture system. “The HST is a large reflecting telescope whose mirrored optics collect light from c...... half the paper...... with the speed at which the universe is accelerating, it allows us to calculate how much time takes for them to reach their current positions. The answer is about 14 billion years. The second method involves measuring the age of the oldest star clusters. The globular clusters orbiting our Milky Way are the oldest objects we have found, and detailed analysis of the stars they contain tells us they formed around 13 billion years ago. The good agreement between these two very different methods is an encouraging sign that we are delving into the true age of the universe." Dark energy is a theoretical repulsive force that counteracts gravity and causes the universe to expand at an accelerating rate. More is known than is known about Dark Energy. There had been many theories about Dark Energy before the HST, but none had concrete evidence. The HST provided evidence
