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]

Descartes: Knowledge is Truth - Descartes: Knowledge is Truth With the emergence of the scientific revolution in the 17th century, views of society and nature were transformed throughout Europe. There were great developments in mathematics, physics, astronomy, biology, and chemistry. The world and its views were changing, and with that change, came a new change in thought, a new change in philosophy. Apart from ancient Greek philosophy, which was centered on finding order in a vast variety of things by searching for a fundamental amalgamating principle, Descartes sought to establish order via some fundamental division....   [tags: scientific revolution, astronomy, perception]

Life of a Star - The most common known star is our very own sun, that is common knowledge, but where did the sun come from. It couldn’t have just appeared from thin air, and it can’t remain forever, for every birth there is a death. Astronomers believe that molecular clouds, or large clouds of gas, are the primary source for the birth of stars. Gravity compresses this cloud into a massive sphere of gas and dust, and once the temperature reaches 15 million degrees it sparks the nuclear fusion, it begins to glow and burn, and voila....   [tags: Astronomy] 694 words

The Milky Way Galaxy - Many people who live on Earth are close minded to what is really out there in the universe. They cannot even begin to fathom the vastness of it and how Earth is just a tiny little speck compared to everything else out there. From the planets to the stars and out towards the edge of the unknown, we can only see what science provides us with. From this, we know that we are nothing but a tiny planet located in a solar system of millions in a galaxy of many more in the universe. A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in....   [tags: Astronomy]

Understanding Black Holes - Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions....   [tags: Astronomy, research papers]

The Solar System - Our solar system was born when, in a spiral arm of the Milky Way galaxy, a giant rotating cloud of dust and gasses began to collapse. Gravity compressed the dust and gasses and the cloud got increasingly hotter and began to spin faster. During the following one hundred million years, the gasses compressed until the center was so hot that nuclear fusion occurred giving off tremendous energy, combining charged atoms of hydrogen to form helium. This process gave birth to a star, our Sun (Our Solar System, n.d.)....   [tags: Astronomy]

Religion Vs Astronomy - Religion and science have always been in direct competition with one another. The ultimate goal of science is to prove the inexistence of God with facts, while the existence in God is simply based on belief and faith. While 95% of the people living on Earth believe in a superior being of some sort, some might say that religion clouds the minds of otherwise logical individuals and makes it impossible for them to pursue the truth of the Universe. Thus, the debate on which view is the right one continues on, while somewhere in the middle stand religious followers who are also scientists....   [tags: essays research papers] 376 words

It is a star among hundreds of billions of stars within our Milky Way Galaxy, and our galaxy is one of billions of galaxies in the universe. Stars live for a very long time; millions, billions, or tens of billions of years so we can never really observe the life of a star; its birth, life, and death.

How a Star is Born - Cosmic Nurseries - Mommy, Where do Stars Come From. Since my entire thesis for this paper is about how a star is born, I guess the first thing I should start out with is by telling you exactly what a star is. Stars are self-luminous gaseous spheres. They shine by generating their own energy and radiating it off into space. The stars' fuel for energy generation is the stuff they are made of --hydrogen, helium, carbon, etc. -- which they burn by converting these elements into heavier elements. Nuclear fusion occurs, which is when the nuclei of atoms fuse into nuclei of heavier atoms....   [tags: Astronomy] 1167 words

The Future of Earth's Moon - The Earth's moon has a great deal of mystery and indefinite discoveries left for us to explore. One of the most talked about topics of the Moon is if we are going to be living there in just a few short decades or centuries. Just imagine yourself, for example, weighing 150 pounds on Earth. If you were to live on the Moon, you would feel like you only weigh 26 pounds. That is because the Moon's gravity is only 17% of Earth's gravity. You would float into the dark sky, and if you weren't attached to anything stationary, you would float off into outer space, and probably never return....   [tags: Astronomy] 691 words

Extrasolar Planets - Humans have longed to believe in extrasolar planets, as surely there have to be planets elsewhere in the universe. Claims of supposedly discovered extrasolar planets can be dated back to 1855 when Captain S. W. Jacobs from the Madras observatory, claimed that he had discovered a planet orbiting a binary system (Jacobs 1855), all the way up until 1991 when a team of astronomers announced then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes 1992). Planets are extremely hard to detect as they are a very faint light source and the light from its parent star is much brighter and essentially blocks out light from a planet (Winters 1996)....   [tags: Astronomy]

Star Formation - The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However, the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system's gravity, so star formation only occurs in a few areas. The sites of star formation in the galaxy are mostly located within molecular clouds – expansive, cool clouds of mostly hydrogen and helium gas....   [tags: Astronomy] 690 words
