The Hale Telescope
Who has not ever, even if just for a brief moment, looked up at a dark but vividly lit starry night sky and wondered how far those seemingly little lights reach, and if that beauty goes on forever, or if it ends at some point. I believe this question has been pondered by mankind since our creation, and early astronomers are proof of this pondering. Telescopes began as a way for these early astronomers to chart the stars and planets and their movements as they searched for more than what just the naked eye could offer them. In the early 17th century, craftsman began making telescopes, though the tools to invent them had been available for centuries before. Early telescope were called spyglasses and needed improvement. Galileo's Optic Tube, also known as the Galilean telescope is an example of the early creation of refracting telescopes. There were a few different makers and models of refractor telescopes but it was soon discovered they could make a better telescope. With the beginning of the 18th century came the reflecting telescope, which is also called a reflector; an optical telescope that uses either a single curved mirror, or a combination of curved mirrors. There are many types reflecting telescopes: there is the Gregorian telescope, the Cassegrain telescope, and the Ritchey–Chrétien telescope. But today, we are going to be talking about one telescope in particular; "the 200 inch Hale Telescope, which for decades stood as the largest telescope on the planet"(1), from 1948 to 1976. The Hale telescope opened up the skies in ways we never imagined.
George Ellery Hale was a man with a vision. He was an astronomer who had big ideas and the know-how on how to obtain the funds to make his dream...

...e realization that telescopes were for far more than just looking at and charting the stars and that there is so much more out there than just our eyes can see. Through the Hale telescope, new theories formed about how the stars and galaxies formed and evolved. Hale helped establish the then new science of astrophysics and through that, we have learned not only of objects existing space unseen to the naked eye or lesser telescopes, and it helped us not only learn where objects were but also what they were and if they changed over time or remained the same. The discovery of Dwarf Planets were possible due to the hale. Through Hale, our view of the universe changed, boundaries disappeared, curiosity grew, a nation and the world were enriched, and dreams became possibilities and knowledge. Yes, The Hale telescope truly opened up the skies in ways we never imagined.
Nathan Hale was born on June sixth, 1755, in Coventry, Connecticut. Richard Hale and Elizabeth Hale were his parents. Nathan had nine siblings. Enoch Hale was the most acknowledged sibling of Nathan Hale. Education was important to both of them. In addition to learning, Nathan was interested in wrestling, football, broad jumping, and women. Resources state that he was “the idol of all his acquaintances”, which was the reason for everyone’s admiration for him. This was one important part of Hale’s remembrance.

The sensitive instruments aboard the SOHO spacecraft have already helped scientists here on Earth discover and explain some of the mysteries of the Sun as well as to confirm some of their theories they previously held. For example, in May of 1998 with the help of the Michelson Doppler Interferometer scientists were able to see with greater clarity the giant convective cells inside and on the surface of the Sun.
Distances so vast that the light from those areas in space is billion years old. Illingworth was able to see these ancient giants with the Hubble Space Telescope. A telescope that is high above the atmosphere, because it can distort the image. 100 sextillion miles or 17,010,779,502.32 light years is the most distant galaxy Illingworth
One of the most notable contributors to the field of astronomy, never actually worked a telescope. The unjust discrimination against women barred one of the most brilliant astronomers of the 20th century from ever actually viewing the stars she was studying. This did not pose a problem however, as Henrietta Swan Leavitt challenged these notions of female inferiority and ineptitude by entering the predominately male field of astrology and excelling. Henrietta Leavitt's prodigious discovery of the period-luminosity relationship amongst Cepheid variable stars would forever change the way we perceive the universe and known galaxies as well as lay the foundation for astronomers such as Harlow Shapley, Hertzsprung, and Edwin Hubble to expand our knowledge of the universe.
It changed the way people viewed the Earth. Neil Armstrong said, “It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn 't feel like a giant. I felt very, very small.” And while only astronauts could truly observe Earth as it looked 230,000 miles away, Apollo 11’s television broadcast gave people their own view so that “anyone following the mission could share, in some measure, that unprecedented leap in perspective.” (Chaikin 54) This “unprecedented leap in perspective” gave people on Earth a sense of community that surpassed societal issues and cultural bias as people recognized how alone humans are in the vast expanse of the universe.
...ld of algebra and physics. His inventions add to his legacy as well, especially the improved telescope. The telescope allowed for many new opportunities for astronomers. His pet door was somewhat revolutionary as well, and it is an invention currently still used by millions today. Newton was an idol of success and proof that hard work and passion equals greatness. He also proved that anything is possible, even with restrictions.
The invention of the bifocals was one of the most important inventions of the 1700s. They have changed the lives of both children and adults that have issues with their eyesight. They rid people of eyestrain and headaches. Also, bifocals rid people of the inconvenience caused by having to shift from one pair of glasses to the other. Bifocals also allowed for more types of glasses to be developed.
Perhaps the most famous discovery is that the Earth revolves around the Sun and the Earth is not the center of the universe (even though he was discredited at the time). Newton was also involved with telescopes. After his growing interest with light bending, he applied his knowledge of the reflecting and refracting properties of light and invented the first reflective telescopes. Newton's reflective telescopes vastly improve the clarity of images as well as escaping chromatic abberation. In order to fully understand the concepts and ideas of how telescopes work, some knowledge of simple optics is required.
Another important individual who drove history was the Italian astronomer and scientist Galileo Galilei. Galileo discovered something so important that it changed the selfish perspective that humans were the center of the universe and led to the growth of human knowledge. Utilizing mathematics and a telescope he had developed, Galileo observed that the planets revolved around the sun and not the Earth. This was a significant discovery because not only did it contradict what the church had taught, it also showed that the universe was not what it seemed. With this truth uncovered, many people began to fascinate over the universe. This triggered people to begin studying space extensively and eventually lead to present day space exploration. Galileo also left a lasting impression upon many great minds, such as Sir Isaac Newton, who used Galileo's research and theories to further his own studies such as the physical laws, and their properties.
I feel personally that the discovery of the atom was an important discovery for the world. With the discovery we are now able to answer questions we never even thought to ask. We are also answering questions some people asked long ago. We can now use our vast knowledge of the atom to measure the stars and be able to tell you what the stars are made of. The atomic discovery also helped us find our periodic table of elements. The periodic table of elements is a huge scientific chart that shows important facts with the help of its formation. There was a lot of constant scientific research that went into making the periodic table of elements and what it is today.
First, you need to know Edmund Halley worked at NASA as an astrophysicist. Halley predicted the orbit of the comet that was later named after him. “He didn't get to see the comet return”-Space.com , but the comet had returned just as he anticipated.
An oscilloscope is an electronic test instrument that is used to observe an electronic signal, typically voltage, as a function of time. In other words, it is a voltage versus time plotter. Oscilloscopes come in two basic types, analogue or digital, and support various features and functions useful for measuring and testing electronic circuits. An oscilloscope is a key piece of test equipment for any electronics designer.
A telescope is a device used to magnify distant objects. Telescopes can be used to look at things on earth or at objects in space. The telescopes for use on the earth are known as terrestrial telescopes and the telescopes for looking into space are known as astronomical telescopes.
Since the beginning of astronomy, astronomers had a unanimous goal: to see farther, better and in greater details.
