Quasars and Active Galaxies
The astronomical world is full of phenomena beyond the average person’s imagination. The technical tools and analytical methods astronomers use are very complex. The enormous numbers and distances are mind boggling. Theories behind astronomical phenomena are based on yet another theory. In order to understand the concept of quasars and active galaxies, one must first have a feel for the astronomical numbers involved. Secondly, a basic knowledge of the tools of the trade, and finally, a working knowledge of astronomical jargon. Once there is a working knowledge of the aforementioned factors, then there is the chance that one could be able to assimilate the complex theoretical properties that are used to discuss quasars and active galaxies.
In order to understand the large numbers used to express the vast distances discussed in astronomy, one needs to relate these numbers to everyday life. During everyday conversation, people may say things like “the national debt is trillions of dollars,” “the lottery is up to 31 million dollars,” or “John Doe is a billionaire.” An astronomer might say that “one astronomical unit equals 93,000,000 miles or that a light-year is 5,870,000,000,000,000 miles.” The human comprehension level of all of these terms is probably nowhere near the actual truth behind how large these numbers really are. To obtain a feel for these gigantic distances used by astronomers, Astronomy Magazine writer, John P. Wiley says it may be helpful to keep in mind that it takes thirty-one years to count to one billion at the rate of one number per second. He also puts a voyage to a galaxy that is a billion light-years away into perspective by calculating how long it would take to get there in a vessel speeding along at 18,000 miles an hour. The trip would take 37 trillion years. When discussing galaxies and quasars, billions are the smallest numbers used (56,57).
The theory of how quasars are created is based on the idea that the universe is expanding. Among astronomers, the popular consensus is that the Earth is in an expanding universe in which the laws of physics will hold true beyond this planet as well. G. Mark Voit, an astronomer at the Space Telescope Science Institute, believes that the beginning of the universe was a time when many galaxies would be visible to the naked eye b...

... telescopes like Hubble, and the Very Long Baseline Interferometry Space Observatory (VSOP), have also proven useful analytical tools for astronomers. Black holes and quasars are interdependent theories. The explanation of black holes leads to an explanation for quasars. These phenomena lead astronomers to believe that there may be places in the universe where the laws of physics may break down, opening doors to new theories for future astronomers (Hawkings).

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
The pointedness of the play is created through a distinct plot path. The observer is lead through the story, seeing first how greatly Amanda Wingfield influences her children. Secondly, the play-goer notes how Tom Wingfield desperately struggles and writhes emotionally in his role of provider- he wants more than just to be at home, taking care of his all-too-reminiscent mother and emotionally stunted sister. Tom wants to get out from under his mother’s wing; his distinct ambitions prevent him from being comfortable with his station in life. Lastly, Laura struggles inside herself; doing battle against her shyness, Laura begins to unfurl a bit with Jim, but collapses once again after Jim announces his engagement and leaves her, again. Each character struggles and thrashes against their places in life, but none of them achieve true freedom. This plot attests to the fact that true change and freedom can only come through the saving power of God Almighty and Jesus Christ, and by letting go of the past.

Just recently a major discovery was found with the help of a device known as The Hubble Telescope. This telescope has just recently found what many astronomers believe to be a black hole, After being focuses on a star orbiting empty space. Several pictures of various radiation fluctuations and other diverse types of readings that could be read from that area which the black hole is suspected to be in.
Quasi-stellar radio sources, more commonly known as Quasars, are the most luminous, and some of the most powerful objects that we have ever observed in our universe. Although Quasars are beautiful to look at, the method that goes into creating them is a continuous process of death and destruction. Quasars may be billions upon billions of light years away, but that has not stopped them from having serious scientific implications, the most famous being that they have helped to prove The Big Bang Theory.

Looking up at the sky on a vibrant night, the vision is naturally lit one with millions of vivacious, glistening stars. The tenacity of this essay is to explore the lifecycle of a star, thence, signify its manifestation in the universe. A fundamental part of our universe is stars. Hence, these miniature luminous forms are essentially very immense in magnitude and it is merely due to their substantial distance from Earth that they appear so trivial. Scientifically, a star is a ball of hydrogen and helium with sufficient mass that it can endure nuclear mixture at its core. A huge, shining ball of plasma, whose lustre is an outcome of thermonuclear fusion are all properties of a star. In addition, they are held together by gravity. By far the star nearest to earth is probably known by all humans as the Sun. A bright star on Orion’s top-left section named as Betelgeuse is so massive that if it was placed where the sun is, it would swallow up Earth, Mars and Jupiter!2 Furthermore, a teaspoon full of Neutron star would weigh about “112 million tonnes” . Particular stars are known to be 600,000 times brighter than the sun ; thus a stars’ lifespan varies between 1 billion to 10 billion years 2.This essay will discuss a star’s journey from as little as a protostar (foetus) till the final stage as a black hole or a white dwarf (old age- death).

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. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass. Galaxies also contain billions upon billions of stars and their diameter can range from 1,500 to 300,000 light years. That’s huge! The Milky Way, the galaxy in which we live in, is one of about 170 billion galaxies in the observable universe. Our Sun is one of the billions of stars in our galaxy, and our eight planets revolve around this star in only a tiny part of our galaxy. “The Earth’s solar system is believed to exist very close to the Galaxy’s galactic plane, due to the fact that the Milky Way essentially divides the night sky into two virtually equal hemispheres” ("All About the Milky"). It definitely makes people second guess the fact of there being life on other planets.
Chanel used Etienne Balsan, a wealthy military office, and Arthur ‘Boy’ Capel, an English industrialist, to help her on her fashion venture (Biography and About.com). She drew on the resources of these patrons using them to help her accomplish her goals. In 1910, Chanel opened her first millinery shop and sold only hats (About.com). Her first clothing success came from a dress fashioned out of an old jersey on a chilly day. During that day, many people asked her where she got her dress, and she offered to make one for them (Biography). Chanel added stores in Deauville and Biarritz and began making clothing (Biography). She had relaxed fa...

The Universe is a collection of millions of galaxies and extends beyond human imagination. After the big bang, the universe was found to be composed of radiation and subatomic particles. Information following big bang is arguable on how galaxies formed, that is whether small particles merged to form clusters and eventually galaxies or whether the universe systematized as immense clumps of matter that later fragmented into galaxies (Nasa World book, 2013). A galaxy is a massive area of empty space full of dust, gases (mainly 75% Hydrogen and 25%Helium), atoms, about 100-200 billion stars, interstellar clouds and planets, attracted to the center by gravitational force of attraction. Based on recent research, 170 billion galaxies have been estimated to exist, with only tens of thousands been discovered (Deutsch, 2011).
