Telescopes in Astronomy
Telescopes are one of man's greatest inventions. The instrument makes distant objects appear closer and they have taken us on a fantastic voyage of learning about and understanding our universe. This paper will focus on the importance of telescopes, major designs, strengths and weaknesses of telescope locations, and where the best place to build them is. In addition, frequencies of light and the role they play in telescopes are discussed. Prior to the telescope the universe was studied, but without the telescope many discoveries would not have been possible. Birth of the Telescope
There is some debate as to who designed the first telescope, however the first person to apply for a telescope patent was Hans Lippershey in 1608 (Cox, 2013). In 1609 when Galileo heard of the telescope he decided to design his own and was the first person to point it up toward space (Cox, 2013). Up until this point it was thought that the universe was geocentric and that the Sun evolved around the Earth. The invention of the telescope helped prove the Copernican system in which all planets evolve around the Sun. This discovery significantly changed our view of the universe and our place in it. Telescope Designs
Designs of telescopes range from reflecting, refracting, and catadioptric telescopes. These three types of telescopes have the "same light-gathering properties, despite differences in size and weight" (Sharma, 2015, para. four). They all have similar purposes. They collect light to focus, magnify and examine it through an eyepiece, but they all do it differently and have pros and cons to them.…...

...for its comprehension. Hundreds if not thousands of astronomers throughout the ages added some valuable pieces of information to astronomical big picture. As Cecilia Payne-Gaposchkin brilliantly putted in her 1976 speech " [...] The old scientist cannot claim that the masterpiece is his own work. He may have roughed of part of the design, laid on a few strokes , but he has learned to accept the discoveries of others with the same delight that he experienced on his own[...] (Astronomy Today, Chap. 16, p 383) What we know today about the universe is a collective work of many generation of dedicated man and woman who continue to add new insight of astronomy great spectrum of universe. Some scholars may add a little, some may add a lot, yet some may change our understanding of a matter in question. Such man were Copernicus, Galileo, Kepler and Newton. Those man are credited with revolutionizing the study of astronomy. The heliocentric theory formulated by Copernicus caused strong turmoil within astronomy, physics and cosmology. Many man of science considered it as contrary to Aristotle’s physics and the Bible. However, some astronomers were engaged in disputes concerning the importance of the discovery of this new system. The interest in astronomical observations caused by the presentation of Copernicus’s theory resulted in astronomical phenomena which became regarded as inconsistent with the scientific paradigm of perfection of celestial bodies, which had existed since......

Telescopes in Astronomy

...Telescopes in Astronomy SCI151 October 08, 2012 Telescopes in Astronomy Telescopes were thought to be created in the year 1608; the earliest known refracting telescopes were created using a tube with a convex objective lens with a concave eyepiece. These devices were designed to assist users in gaining a better view of things that were further away. Initially they were primarily used aboard sea going vessels it was eventually found that they can also view things such as the moon, stars and anything in the heavens much more closely. Unfortunately back in the early 17th century the telescopes were not that powerful and it was not until the mid 17th century that more powerful telescopes were being built. Later astronomers realized that if you build a strong enough telescope and place them in the right spot the view of the night sky could be scientifically spectacular. * How Telescopes Changed Our Lives * Telescopes have been an instrumental tool for how astronomers view the stars, ever since Galileo used his in 1609 to look towards the sky and study the moon and the Milky Way galaxy as whole, the world was forever changed. It was with these devices that we learned that the earth is not the center of the solar system or the universe. With telescopes we learned that the moon has craters and mountains, and that Jupiter has storms and that other planets also have their own distinct weather patterns. With newer and more powerful telescopes we learned that......

Stars and Telescopes Paper

...STARS AND TELESCOPES PAPER Stars and Telescopes Paper University of Phoenix SCI 151 Telescopes in Astronomy Some basic knowledge of telescopes in astronomy will be examined in this paper. For many years telescopes have been used for observing celestial objects. Telescopes have changed our understanding and knowledge by observing objects in the universe. New developments have been discovered based on measuring the wavelength omitted from the celestial objects with improved technology creating many kinds of telescopes. Studying different stages of stars in detail can be done by using different telescopes that are used for specific purposes. This paper will touch base on the history of telescopes, the development of telescopes, and the function, and purposed of telescopes in our universe. Since the seventeenth century the telescope has become one of the important instruments to reveal unsuspected phenomena in the heavens and universe. The controversy between traditional geocentric astronomy and those favored the heliocentric system of Copernicus has had major influence from the discoveries from the telescope. The telescope gave men the opportunity to observe things that mankind had never seen before, increasing men’s senses and knowledge of objects in outer space. Originally the invention of the telescope was a prototype of modern scientific instruments, not an invention of scientists. Craftsmen created the instrument we refer to as the telescope.......

Astronomy Paper

...Astronomy paper Introduction: Searching for extra-solar planets is not a very easy task. Because most of the times we find them by not actually looking at them but by the effects they produce mainly on the star around which they are rotating. It is because planets look like just a dull spec of light through a telescope. The distance between us and a nearby planet is very large. In our scale model it will be like looking at a dust particle in Thunder Bay Ontario if we are sitting in Halifax with our telescope. That’s why astronomers have adopted various techniques to find extra-solar planets. In most of the techniques we focus on the star around which planets are rotating and by noticing the changes occurring in star we can decide whether that star has planet(s) or not. The following methods are used for that purpose. 1. Astrometry 2. Radial Velocity Method 3. Pulsar Timing 4. Transit Method 5. Gravitational Microlensing Astrometry: This is the oldest method used to search extra-solar planets. This planet is basically used to find the mass of thee planet. This method is based on the gravitational effect of planet on its host star. As the planet rotates around its star, it applies gravitational force on the star and makes the star to move under the effect of its (planet) gravity. Thus, both the star and the planet revolve around a common center of mass also called center of gravity. Thus, the position of star always keeps on changing,......

How the Telescope Changed Astronomy

...Studying the Stars: How the Telescope Changed Astronomy As long as humans have been able to see, they have looked at the stars with either with worship or with wonder. The earliest cultures of humanity created their deities from the heavens, most of which were seating upon the glowing specks of light that show through the black night sky. Humans only have a few senses that let them interact with and receive information from the environment, sight being the most useful. Trying to figure out what something far away is, in a star’s case, far enough away to make a giant ball of burning helium look like a speck, is something that requires a tool. Telescopes were the first tool that really helped humans see into the heavens, letting them study the stars and the ‘wanderers’ which eventually were found out to be planets moving around the sun (although at the time they were discovered, it was thought that everything revolved around the earth); albeit all of these stars and planets were discovered before Galileo’s telescope. The tool still helped gain better calculations of the stars, which helped Galileo support Nicolaus Copernicus’ heliocentric (sun-centered) solar system as opposed to the geocentric (earth-centered) solar system that people in those times believed. With Isaac Newton, one of the most famous physicists, discovering most of laws of motion through his studies in astronomy, Philosophiae Naturalis Principia Mathematica, one of the greatest works in the Scientific......

James Webb Space Telescope

...Asif Bajwa Astronomy 101 Professor Houser 12/11/2014 James Webb Space Telescope Since the first astronomers pointed telescopes at the sky, they have sought to see more. See farther and deeper. Space astronomy changed on April 24th 1990 with the launch of the space shuttle Discovery carrying aboard it the Hubble Space Telescope. A lot of people think we launched Hubble into space to get it closer to the stars but the real reason is the Earth's atmosphere both distorts and blocks light coming in from space. In space, beyond the atmosphere, the stars don't twinkle, instead they shine firm. That allows for the sensational images we've become accustomed to seeing from Hubble. But that wasn't Hubble's only benefit, it was also one of NASA's great observatories. There are many of these observatories in space but most are outfitted to answer one or two specific questions. Hubble was designed to be as inclusive as possible, it was supposed to answer as many questions as you could ask. At least as far as its design allowed. And Hubble succeeded very well at that. The Hubble Deep Field, perhaps the most important image ever taken by Hubble, shows us galaxies stretched all the way across the universe, up to ten billion light years away. Light that has taken billions of years to reach us in our corner of the universe, so we see these galaxies not that as they are today but as they were when the light left them. And in the end, after zooming in as much as possible, we see......

Telescopes in Astronomy

...Telescopes in Astronomy Jennifer Boyer SCI/151 June 12, 2015 Robert Austin Telescopes in Astronomy What people currently know about the universe, along with all of its contents, is due in large part to the invention of telescopes. This paper discusses the science of sunlight and stars by explaining how the telescope has changed people’s view of the universe, as well as their place in it. This essay also discusses the major designs of telescopes, provides a list of each design’s strengths and weaknesses, describes the best places to build ground-based telescopes and why astronomers choose those places, and contrasts the strengths and weaknesses between building telescopes on Earth, in orbit, or even on the moon. Additionally, this paper explains how different frequencies of light tell more about the birth, life, and death in the nature and properties of the Sun, stars, and the universe. Lastly, this essay explains how telescopes operate in wavelengths of light that range from radio waves to gamma rays. How Telescopes Changed People’s View The invention of the telescope significantly impacts the way people in the past and present view the Earth, other planets and solar systems, as well as the universe as a whole (Bennett, J., Donahue, M., & Schneider, N., & Voit, M., 2015). Until the invention of Galileo Galilei's (1564-1642) simple telescope, many people thought that the earth was the center of our solar system (Bennett, J., Donahue, M., &......

Telescopes in Astronomy

...Telescopes in Astronomy Cary Lingle PHY 107 June 25, 2013 Professor Worek Telescopes in Astronomy Peering out beyond the confines of the Earth was a daydream for early scientists. Staring into the heavens from the Earth limited the scientific community’s ability to study the cosmic bodies above the Earth’s surface. As curiosity grew to explore the Sun, moon, stars and far-reaching corners of the universe, creativity was sparked leading to the development of tools like a telescope to assist scientists with examining outer space and its contents. The development of the telescope began in the hands of a Dutch lens maker, Hans Lippershey. Lippershey developed a device consisting of a tube and a lens allowing the user to view objects up close. Galileo Galilei expanded upon Lippershey’s design creating the modern day telescope using a concave lens. Galileo used his telescope view the items in the night sky including the Milky Way. Galileo revealed that the Earth was not at the center of the universe that was a contrasting view from previous scholars. The development of the telescope has lead to significant discoveries including the moon's effect on weather patterns on Earth and in space black holes, stars' lifecycles and galaxies beyond the Milky Way to name a few. The ability to study the Sun has given scholars the ability to determine the age of the Sun, planets and stars in the night sky. The first telescope's original design, consisting of a tube and lens, gave the......

...Summary 4: The Birth of Astronomy The Universe was first scientifically identified by Aristotle. He saw the cosmos as a series of spheres with Earth in the centre. Later on Ptolemy, the last Greek philosophers, also adapted Aristotle’s idea. Ptolemy created Geocentric models of the Universe, such as the Ptolemaic model have the Sun, planets and Moon orbiting Earth. Nicolaus Copernicus (1473-1543) was one amongst the most important figures in Renaissance astronomy. Nicolaus Copernicus in his posthumous publication revealed that the Sun, was at the centre of the Solar System and not the Earth. The heliocentric model explains retrograde motion and observed brightness variations of the planets. Galileo Galilei, the first experimental scientist. Galileo made observations of the Sun, planets and Moon through his telescope. He gave experimental evidence against the heliocentric theory and supporting Copernicus’s heliocentric model. Kepler gave the three laws of planetary motion. His laws state that (1) planetary orbits are ellipses having the Sun as one focus, (2) a planet moves faster as its orbit takes it closer to the Sun, and (3) the semi major axis of the orbit is related in a simple way to the planet’s orbit period. Summary 5: Astronomical Tools An astronomer’s most useful tool is the telescope. It is a device designed to collect or gather as much light as possible from some distant source and deliver it to a detector to study them in detail. A telescopes light-gathering......

...Astronomy SPACE EXPLORATION: FROM THE PAST TO THE FUTURE Ever since the beginning of time, mankind has been fascinated with wonders of space. Before the mid-1900s, all mankind could do was gaze at the stars from Earth and wonder what it would be like to go into space. Man would look through telescopes and make theories on how the universe worked. During the mid-1900s, mankind finally was able to send a man into space and explore the wonders of space first hand. So why do humans explore space? Well, it is our fascination with the unknown. At first, all mankind did was look up and wonder how things became what they are now. We started to think that all celestial bodies revolved around the Earth, and the Earth was the center of the entire universe. Galileo Galelie later disproved this theory. Even with growing knowledge in the field, it was not until 1957 when the first Earth orbiter, the Soviet’s Sputnik 1, was sent into space and placed in orbit at an altitude of 1,370 miles and weighed ! 184 pounds. Later in that year, the Soviets sent Sputnik 2 into space with a dog named Laika. Laika was the first animal to venture into space. Then in 1985, the United States successfully sent their very own satellite into space. In 1960, the Soviets launched to dogs into space and successfully returned them to Earth. From this point started the space race. The space race was a challenge between the USSR and the United States to see who could land a man on the moon first. In 1961,......

Astronomy Then and Now

...Astronomy: Then and Now Have you ever heard the saying you can’t teach an ole dog new tricks? What about the one where three old dogs teach new tricks? I’m sure you have heard that one, anyone who knows about our solar system can thank the three old dogs. Well, they’re not dogs at all, and at their time they weren’t old but in our time their long gone. Of course, I am speaking about Ptolemy, Copernicus, and Kepler. Funny thing is each one of them challenged and changed their predecessor's work, for the better of course, but we will get to that later. We have these three men to thank for a whole lot of new tricks. To name a few would be, our solar system, the way we form our maps, and we can’t forget the numerous mathematical formulas used to make ideas come to life. In this research paper, we will touch base on the lives of three great astronomers and the tricks they have taught us. We will also see how astronomers of today contribute to our everyday lives. Some say that our first astronomer was a great astronomer. Other say, “Ptolemy was the only great astronomer of Roman Alexandria.” (Brown, 2016) It’s all a matter of opinion, but what we cannot deny was Ptolemy was a great astronomer of his time and today. We do not know much about Ptolemy’s personal life. What we do know about him came from his work. He was born around 85ce in Egypt to a Greek family even though he bore a roman name. To say Ptolemy was diverse is an understatement. He was also diverse in his......
