Hubble Space Telescope Essay

583 words - 2 pages

The Hubble Space Telescope The Hubble Space Telescope is one of the worlds most powerful earth-orbiting reflecting telescopes. With its capability of producing images from any wavelength, the HST is the eyes of the universe for scientists on earth.The HST has a capability of operating at any wavelength from a near infrared level to a visible range to an ultraviolet level. Because of this capability, scientists can view toward the outmost reach of the universe. The HST has a 2.4 meter objective mirror and is able to observe different types of wavelengths. Once it locates an image from any wavelength, the HST records the images it receives and then sends the images back to earth by means of radio waves in digital form.The construction of the HST began in 1981 with the assembly of its' precision ground mirror. By the end of 1985, the entire spacecraft was complete with the scientific instruments, optical components, and remaining hardware intact and prepared for launch. Although scheduled for launch in 1986, the project was later postponed due to the space shuttle Challenger disaster. During this period, HST was subjected to intense tests and observation in order to prepare its duty in space. The HST was finally launched aboard the STS-31 mission of the space shuttle Discovery on April 24, 1990.Shortly after its launch in 1990, an error was found in the HST main mirror, which caused the telescope to operate improperly. The main mirror was shaped too flat toward the edge of the lens itself. This caused the images to appear as a blur upon use of the telescope. The mirror could not be fixed. So to correct the problem, scientists developed a corrective lens, similar to a contact lens, to compensate for...

This school bus-size telescope was brilliant: it consists of many high-technology instruments that can detect spectrograph, optical image. Without the limitation of these two factors, Hubble Telescope is able to send back image all the time with a better image quality. Thus, Hubble Space

2412 words - 10 pages ). All of Hubble’s efforts went futile as he wasn’t awarded the Nobel Prize during his lifetime as he died in his deathbed in 1953. Hubble’s legacy continues on today, and in his honour the first ever telescope to be sent in space is named after him. Hubble was indeed a pioneer and visionary who truly revolutionized the study of the universe and the vast field of astronomy. Works Cited Faiz Khan-250688240 Chris Racknor Astronomy

The classification system for galaxies that Hubble created has been passed down by other researchers for nearly a century. As a tribute to Hubble’s profound work in the field of astrophysics, NASA named their space telescope after Edwin Hubble. Many university facilities, a

After serving in World War I, Hubble accepted a position at California’s Mount Wilson Observatory to help build the Hooker telescope, at the time, world’s largest telescope measuring 2.5 meters or 100 inches. Following the completion of the Hooker telescope, Hubble worked closely with calculating the

Just like Seneca, the Roman philosopher, said," Our universe is a sorry little affair unless it has in it something for every age to investigate..." and it seems to be true the universe has something to reveal to the different generations. On April 24, 1990 a new invention was launched 353 miles above the Earth's surface, it was launched to give scientist more information about the universe. This new device was the Hubble Space Telescope (HST

The year that the first computer controlled telescope came into being (1976) this was a huge technological advancement for astronomy at that point. The last major telescope created which was also launched into space was the Hubble Space Telescope which was set above the harsh effects of our earth’s atmosphere at around 600 km height. The Hubble space Telescope was launched

For telescopes on the ground, locations that are dry, calm, dark, and high work best. Dry locations remove as much of the weather variable as possible, calm places cut down on the atmospheric turbulence, dark locations reduce light pollution, and high areas raise the telescope above part of the atmosphere (Bennett, 2012). The limitations ground

This makes the images that are obtained have a quality that is as good as those taken from space, with the best image so far being twice as sharp as an image from the Hubble Telescope taken in Chile by the Magellan-Clay telescope.
