Essay about Telescopes in Astronomy

The telescope is an optical instrument designed to make distant objects appear nearer. It contains an arrangement of lenses or mirrors or both that gathers visible light, permitting direct observation or photographic recording of distant objects. (Lacki, B. C. 2011). With the use of telescopes we have been able to learn a lot more about the planets in our universe. It has helped us understand about some of the history of everything around us. Also it has been able to track asteroids and comets or any randomly flying objet in outer space that might become threatening to our planet.

Meridian has been manufacturing fine telescopes for 80 years and has developed a well-earned reputation for quality craftsmanship. The company itself produces and sells two distinct lines of telescopes, which are produced in its 200,000 square feet facility. Furthermore, both lines have been developed to appeal to distinct target audiences who have an interest in the company’s products. The older line, for which there has been steady demand, consists of small professional telescopes that ultimately have laid the foundation for Meridian’s strong reputation. Following the success of

however, many crafts like the Hubble, were put in by the space shuttle. The space

The Discovery Channel Telescope secured the telescope’s name and they got the use the telescope first. They used the telescope for their television networks to make images. “Astronomers declared the instrument fully operational on the first day of 2015, ending a commissioning period that lasted 2½ years. In their advantage “The vast array of science projects that will be possible with this telescope will dazzle readers of this magazine for years to

Oschin Telescope at Palomar Observatory near San Diego. It is currently about 97 times farther from the

Generally in astronomy, light pollution and thick atmospheres distort and impair images from optics like telescopes. Light pollution crowds out the targets being observed, while the atmosphere dims the light received from them. When choosing the location for the building of a new telescope, it is highly beneficial to build in areas with a thinner atmosphere and low light pollution . This is why mountaintops are typically the preferred sites for new telescopes, and why Mauna Kea is a highly desirable location. A new telescope called the Thirty Meter Telescope (TMT) is revolutionary in

We look for things that we can’t see by looking through special powerful telescopes that help us see the things we can’t from the naked eye. Many special telescopes today at NASA are those that can see things our eye itself cannot. These telescope’s lenses are the most powerful in the world. They see things our eyes can’t like dark matter. Like when dark matter was discovered. W. Kent Ford confirmed the existence of this “missing mass”. He observed a resembling phenomenon. The mass of the stars visible in a typical galaxy is about 10 percent required to keep stars orbiting their galaxy's center. Speed with which stars orbit the center. Accoring to http://www.britannica.com/science/dark-matter “Indeed, orbital velocity is either constant or

Although telescopes were a revolutionary discovery they would come at a price. As described in my second site “Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope...Because of their sensitivity to environmental factors, ground-based telescopes would need to be set up in specific spots. Scientists and engineers must take different physical factors into consideration when finding a suitable location to place a ground-based telescope.” These disadvantages make it difficult to get the full experience of using the telescope correctly and using it to benefit the viewer.

The James Webb Space Telescope budget uses a 6m gold plated Beryllium reflector. I wonder how thick and how much it cost for the gold compared to the project. I do agree with you though that the scarcity of gold should not be wasted with its $8 billion budget (source below). Hopefully everything works out and if does come down, I hope the gold plate can fall at a safe distance near me.

Also, the azimuth was less than 180 degrees which gave an estimate at where it would be in the sky.

The Hubble telescope is a compound telescope design where light enters the telescope through the opening and bounces off the primary mirror to a secondary mirror. Then the secondary mirror reflects the light through a hole in the center of the primary mirror to a focal point behind the primary mirror. At the focal point, half transparent mirrors distribute the light to the various scientific instruments. The Hubble Telescope mirrors are made of glass and coated with multiple layers of pure aluminum that are three-millionths of an inch thick and a coat of magnesium fluoride that is one-millionth of an inch thick to make them reflect visible, infra-red and ultraviolet light. The primary mirror weighs 1825 pounds and the secondary mirror weighs in at 27.4 pounds.

As proposed in an article posted on amazing space.org, “The telescope, a basic reflector with a 94.5 in (2.4 meters) mirror.” While also having being a second mirror that the light bounces to to. Within that mirror, many instruments were compacted together that allowed for clear and visible views in infrared and ultraviolet light. It was different compared to any other ground based telescope whereas it allowed astronomers to observe and witness details that had never been seen before due to Earth being in the way for those other telescopes. The telescope revolves around the earth completely every ninety-seven minutes at the speed of five miles per second, allowing for many observations in space. The observations occur when light hits the main mirror and then bounces towards the second mirror in which the second one focuses the light. The telescope began to be created in 1977 and was originally supposed to launch during the year of 1985. Unfortunately an accident had occurred when a space shuttle challenger exploded and flights into space took a halt. It was finally launched on April 4th of 1990 once the halt had stopped. The improved observations had begun and the history of astronomy had changed. Unfortunately there were some minor setbacks that had to be dealt with. One setback was that the primary mirror was ground incorrectly in which the curve of it was too flat. It was off just

Although I am undecided, I have demonstrated an interest in astronomy because I find the mysteriousness of outer space to be absolutely fascinating. Because I have always lived in Los Angeles I have never really had the pleasure of seeing a night sky full of stars, but after a camping trip I finally saw the stars and fell in love them. Although I am fascinated with outer space, I do not think that I would ever want to go to outer space since I am terrified with what may be out there, and how it seems to be never ending. Despite this I would still like to study the stars and everything else that is in outer space since it has the capability to provide insight as to how the human race can survive for millions of more years. Additionally, the possibility of there being another planet where life exists, like in Star Wars, is something that would love to discover.

Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun.

Since the beginning of recorded civilization, stars played a huge role in religion and proved vital to routing. The invention of the telescope, the discovery of the “laws of motion” and gravity in the 17th century prompted the
