Before telescopes, all the world knew about the world was what humans could see with the naked eye. The world outside of Earth was an unknown--until telescopes was invented. Since then, many discoveries have been made about outer space and Earth. New and better telescopes have been made since the first telescope, and some have been out in space for years and are very large. One of these telescopes is known as the Hubble Telescope.
Named after astronomer Edwin P. Hubble, the Hubble Telescope was launched on April 24, 1990. The Hubble Telescope has seen stars die and born. Hubble has also seen galaxies trillions of miles away. This telescope travels around the Earth at five miles per second and weighs about twenty-seven thousand pounds. …show more content…
Scientists figured out that the wrong thickness was used on the first mirror. This was a major problem. The mirror’s thickness was off by only one fiftieth of a human hair. Since exchanging the mirror was unreasonable and unpractical, scientists decided to try a different solution. This solution was to install replacement parts to counter the mirror flaw. This would act like a pair of glasses to fix vision. To make this happen, five pairs of corrective mirrors were put on the Hubble Telescope. After this, the telescope began to do the job it was meant to do.
The Hubble Telescope has a very intricate way of taking photos. The telescope doesn’t use film at all to create images. Instead, the Hubble uses CCD (Charge-Coupled Device) to take photons of the light. After this, various filters are added to the pictures to add color since the Hubble Telescope doesn’t take pictures in color. The Hubble Telescope can detect visible spectrum and as well as ultraviolet or infrared light. These are invisible to the human eye. The telescope normally takes multiple pictures of the same object with multiple
