Black Holes and My Love for Astronomy - When I was growing up there were things in life that always seemed to fascinate me. Most of them were usually science based. Things like elements on the periodic table, where did the stars come from and what lies at the end of the universe. I think the one question that always had my attention was what is a black hole. I can remember asking my parents when I was at about the age of eight or nine what a black hole was, and what was its purpose. Like most people, not really knowing themselves what a black hole was they kind of made up some wild crazy story hoping that I was to young to know the difference between fact or fiction....   [tags: astronomy, ] 837 words

The Small but Vast Field of Astronomy - Astronomy is a field where one looks into the great expanse of space and tries to find something that will bring the world a little closer to fully understanding the universe. The road to becoming an astronomer is not easy, as one must get an excellent education, hope that there are actual job openings, and then obtain a steady position. In order to be an astronomer, it is required to have a doctorate’s degree in either astronomy or physics (“Physicists and Astronomers”). After finishing their studies, an astronomer can really only hope to be lucky and secure a position working for the government, a university, or a college (“Astronomer Job Description”)....   [tags: astronomy, universe, astronomer]

Haley's Comet is Only Comet Visible from Earth with Naked Eye - A comet is a small icy body that travels in an elliptical orbit around the sun. Halley’s Comet, or 1P/Halley, is the most well-known “periodic” comet that orbits the solar system and returns to Earth’s vicinity approximately every seventy-six years. It is one of the only comets that can be seen from Earth that is visible to the naked-eye, and can appear twice in one’s lifetime. The comet’s last visit was in the year 1986, and it is calculated to return mid-2061. Halley’s Comet has been sighted and recorded for thousands of years by humans....   [tags: orbit, astronomy, solar system] 899 words

The Controversy over the Discoveries of Galileo Galilei - Galileo Galilei, born February 15th 1564 in the town of Pisa, a man who played a significant role in the Scientific Revolution, he was a man of many talents as he was not only an artist, astronomer and engineer he was also a philosopher, mathematician and physicist to name a few. One of his most outstanding improvements were those made to the telescope, although Galileo’s observations, made using the telescope, would be one that would arouse much attention and create a great controversy. Galileo the eldest of six children was born in Pisa in 1564, several years later his family moved to Florence, he was then educated under the Camaldolese Monastery at Vallombrosa a town southeast of Floren...   [tags: Biographical Essay, biography, Astronomy] 791 words

Is the Hubble Telescope Worth the Cost? - The Hubble space telescope is a deep space imager used by NASA to explore space. It collects light and magnifies images, and gives Astronomers the most detailed images known to man. Hubble has been at work since April 25, 1990, and celebrated its 20th anniversary in orbit April 24, 2010. Twenty years in service, and still being the leading source for space news says a lot about Hubble's overall longevity and productiveness. Over 6000 scientific articles have been published based on Hubble data, with some of its discoveries being so significant that NASA would have needed multiple satellite missions to accomplish the same results....   [tags: synthesis essay, astronomy]

Using Parallax and its Formula to Measure Distances: Science Project - As my science fair topic, I chose to test the accuracy of using parallax to measure distance. I chose this topic because it relates to two of my favorite topics: mathematics and astronomy. Parallax uses a mathematical formula and is most commonly used to measure the distance between celestial bodies. From my research on parallax, I found how to measure it, and how to use the parallax formula to measure distances. Parallax is defined as “any alteration in the relative apparent positions of objects produced by a shift in the position of the observer” (Columbia Electronic Encyclopedia 1)....   [tags: Celestial, Mathematics, Astronomy]
