The supernova that changed everything, it was the Supernova 1987A. The word Nova means new star. This supernova was the most recent one since 1604 that was mistakenly thought of as the birth of a new star until the invention of the telescopes. I can only imagine the delight and satisfaction that these scientist felt when they witness something so energetic that is the Supernova 1987A. The people that was lucky enough to be living in the Earth’s Southern Hemisphere would have been able to see the after math of Supernova 1987A, the new star was easily visible to the naked eye for many months. This new star was studied by astronomers since that epic night. The Supernova 1987A exploded 170,000 light years away, on the outskirts of the Tarantula Nebula in the Large Magellanic Cloud. The light from the Supernova 1987A traveling a whopping 186,000 miles per second finally reached Earth on February, 23-24, 1987, this just goes to show how vast our galaxy is that it 170,000 light years to see. Astronomers used this as an opportunity to study the closest thing that created our universe.

Supernova 1987A was a type ll supernova, the type of characteristic that explain this is a violent stellar event, caused by the implosion of a star. The star that exploded was a Sanduleak -69 o 202, a blue supergiant. When astronomers found this out they were surprise, because they were not aware that Type ll supernova was able to become that hot and turn that color, since this discovery they now accepted that supergiants are a normal progenitor for some supernovae. The supernova1987A was a core-collapse supernova, meaning that the core of the star collapsed. Astronomers believe that a neutron star would form, because of the neutrino emissions from the supernova event indicated, they would now realize today that, that was not the case because they cannot find any evidence of a neutron star.

I didn’t understand at first why these astronomers was so crazy about this supernova. I didn’t understand what was happening. I only understood that a star died and when stars die they explode sometimes. I thought awesome fireworks. I see some every 4th of July. I know realize that I was not understanding the full extent on what was going on 170,000 light years away from the earth. I soon came to be aware that the very thing that make up our body, where everything is started from, you know our atoms is the very energy that this event spew out into space when the explosion occurred. The conclusion of this supernova does not stop there some astronomers believe that this was the beginning that triggered the way our solar system was set up, which caused the mutation and drove the process of evolution of life on Earth 5 billion years ago. I can understand now how important of a discovery this was to them, to be on the brick of creation and being able to witness it with their own eyes is amazing. Not only witnessing it, but now being able to study and maybe even answer some questions because of it, for as long as that light reaches the Earth. Supernova1987A is truly an amazing discovery and I am glad that I learned about it so much that I plan on buying a portrait of its overlay of radio emission by a Hubble space telescope image of it, if I can find one.

New Pulsar

...New Pulsar Star Discovery Throughout the universe many natural wonders occur on a moment to moment basis. These natural wonders have occurred for more than 14 billion years and will continue to occur as long as the universe exists. Some of these natural wonders are the super nova or the passing of the moon in front of the Sun to create an eclipse. One such wonder that has brought on quite the curiosity of late is the Pulsar. Discovery of the Pulsar Discovered in 1967 by Jocelyn Burnell, Pulsars are neutron stars that appear to pulse because of the rotation of the star ("Neutron Stars and Pulsars – Introduction," 2006). Jocelyn Burnell is an astronomer and an astrophysicist born on July 15, 1943 in Belfast Ireland (CSU, n.d.). Jocelyn Burnell earned her physics degree at the Glasgow University, Scotland in 1965 and was the first person to discover the pulsar, which are stars that release regular bursts of radio waves (CSU, n.d.). Jocelyn Burrell’s discovery was a milestone in the history of astrophysics (CSU, n.d.). In addition, she was involved in the construction and operation of the telescope and was responsible for monitoring and interpreting the recordings of radio transmissions once the telescope had become operational in July 1967 (CSU, n.d.). Summary of the Article An international team of astronomers have discovered new information about a star that man has been cognizant of for over a decade. This star, called PSR B0943+10, operates in a different......

Problem of Evil

...serious war’’ that the largely irreligious crew has waged with him during the long mission. He thinks particularly of the ship’s doctor, Dr. Chandler, who sometimes professes himself willing to believe that ‘‘Something’’ created the infinite vastness of space and everything in it, but cannot accept that a being so powerful could possibly care about ‘‘us and our miserable little world.’’ The narrative goes on to reveal more details about the mission. The ship had been sent to examine the aftermath of a supernova—the explosion of a star, during which it burns with an intensity and a luminosity that may be a billion times that of the Earth’s sun. Following such an explosion, a star becomes a white dwarf, a body of very dense matter. These scientific details are imparted almost incidentally as the first-person narrative continues. When the ship reaches the solar system surrounding the white dwarf, they are surprised to find that the outermost planet survived the force of the supernova explosion, and that it contains a clearly demarcated vault. Within it they find artifacts recording the accomplishments of a highly advanced civilization. The narrator reports that his colleagues have...

Super Nova Poem

...The force of nature produced something so small with much effort. It was in this poem that I saw an elaborate explanation of the birth of a star stretched out into an array of words. The "Red Giant"a dying star in it's last stages of evolution, Is the star that will soon be replaced towards the end of the poem concluding a new star. The title Super Nova meaning a star is born contributes to the readers understanding because it is the "symbol" Object or action that means more than it's literally meaning, of the poem and the whole meaning of it really. The author Udiah I don't think is speaking directly, I think the poem is in third person and he makes it seem as if the planets are telling the story themselves or some foreign force. The situation in the poem is the amount of force in outer space that it takes for an old star to die and new one to come about. Although the poem is very vast and interesting there are some references that need explaining such as how the birth of a star happens exactly, I don't think an average reader would understand necessarily the science behind it. Some of the words I looked up helped me find better meaning in the poem, Nuclear Fission a nuclear reaction of a radioactive decay process in which the nucleus of a particle splits into smaller parts. This particular word is used at the beginning of the poem, means to me that the red giant has exhausted it's supply of hydrogen and can no longer hold it all in anymore, there forth letting go.......

Insecticidal Property of Acacia Seeds and Bark for Termites

...Life Cycle of Stars The Birth of a Star In space, there exists huge clouds of gas and dust. These clouds consist of hydrogen and helium, and are the birthplaces of new stars. Gravity causes these clouds to shrink and become warmer. The body starts to collapse under its own gravity, and the temperature inside rises. After the temperature reaches several thousand degrees, the hydrogen molecules are ionized (electrons are stripped from them), and they become single protons. The contraction of the gas and the rise in temperature continue until the temperature of the star reaches about 10,000,000 degrees Celsius (18,000,000 degrees Fahrenheit). At this point, nuclear fusion occurs in a process called proton-proton reaction. Briefly, proton-proton reaction is when four protons join together and two are converted into neutrons; an 4He nucleus is formed. During this process, some matter is lost and converted to energy as dictated by Einstein's equation. At this point, the star stops collapsing because the outward force of heat balances the gravity. The Hydrogen Burning Stage The proton-proton reaction occurs during a period called the hydrogen-burning state, and its length depends on the star's weight. In heavy stars, the great amount of weight puts a large amount of pressure on the core, raising the temperature and speeding up the fusion process. These heavy stars are very bright, but only live for a short amount of time. After the energy from this deuteron-hydrogen fusion......

...White Dwarfs There are about 2,500 stars visible to the naked eye at any one time or at any one point on the Earth, and 5,800-8,000 total visible stars. However, in total there are about 200-400 billion within the Milky Way. White dwarfs are estimated to be about 12-13 billion years old. Another name for the White Dwarf is called a Degenerate Dwarf. White dwarfs are very dense in its mass compared to the sun even though its volume is compared to the earth. Its brightness comes from the emission of stored thermal energy. In January 2009, it was eight stars found nearest to our sun. That project was named the Research Consortium on Nearby Stars. In 1922 William Luyten created the name White Dwarf name. White Dwarfs are thought to be the last evolution of all stars that mass is not high enough to be a neutron star. The material in white dwarfs no longer undergoes fusion reactions, so the star has no more energy. A white dwarf is very hot when it’s formed but since it has no energy it gradually radiate away energy and cool down. This means that its radiation, which initially has a high color temperature, will start to lessen and redden with time. Over a very long time, a white dwarf will become a cold black dwarf by cooling to temperatures at which it will no longer emit significant heat or light. It has been said that White dwarfs can’t be older than the universe which is about 13.7 billion years old. Even the oldest white dwarfs still are at temperatures of a few......
