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.…...

Lifecycle of Stars

...forming oxygen, nitrogen, and eventually iron. At this point, fusion stops and the iron atoms start to absorb energy. This energy is eventually released in a powerful explosion called a supernova. A supernova can light up the sky for weeks. The temperature in a supernova can reach 1,000,000,000 �C. The core of a massive star that is 1.5 to 4 times as massive as our Sun ends up as a neutron star after the supernova. Neutron stars spin rapidly giving off radio waves. If the radio waves are emitted in pulses (due to the star’s spin), these neutron stars are called pulsars. The core of a massive star that has 8 or more times the mass of our Sun remains massive after the supernova. No nuclear fusion is taking place to support the core, so it is swallowed by its own gravity. It has now become a black hole which readily attracts any matter and energy that comes near it. Black holes are not visible. They are detected by the X-rays which are given off as matter falls into the hole. 1 STAR LIFE - LEVEL 1 In the list below you will find the steps in the life cycle of a massive star. The steps are not in order. Carefully cut each step out with scissors. Using the information you have learned about massive stars, place the strips in the order in which they occur in a star’s life cycle. 1. A supernova occurs. 2. Nuclear fusion occurs which causes the star to glow. 3. If it is a massive star, a neutron star forms. If it is a super massive star, a black hole......

Cretaceous Mass Extinction

...becomes the key point for the solutions. Till now, four main theories which are gradualism, supernova, volcanism and cosmic impact, have been put forward to solve the scientific problem. And, the last three models belong to catastrophism in favor of sudden extinctions, opposite to gradualism. However, this essay will attempt to argue that cosmic impact should be the most reasonable explanation due to evidence that have been found up to now. In order to demonstrate it, this essay will analyze these different theories separately paragraph by paragraph, along with corresponding findings. In addition, it will compare rival theories. In the ‘gradualistic’ view (theory of gradualism), the Earth was a slowly evolving word and the turnover of living species had to be slow. According to Frankel C. (1999) an ammonite specialist reported in the mid1980s that the ammonite species declined progressively over more than 100 meters of strata- a drawn-out interval of one million year at least. Besides, the last one was found more than ten meters below the K-T boundary, indicating that the last of the ammonites had died 100000 years before the predicted time of catastrophic impact. However, it might be the scarcity of ammonite fossils that make the extinction look gradual.(Frankel C., 1999). Probably, after more fossils could be found, answers may turn completely different. In terms of supernova theory, suggestion was made that a nearby star exploded and showered the earth with strong......

Black Holes

...structure and make-up of the sun’s corona. The last wavelength we detect with telescopes is the gamma ray. Gamma ray detecting technology has only been around since the 1960’s. Gamma Rays are difficult to detect because they pass through most materials, so they cannot be reflected by a typical telescope. However, the tools of high-energy physics are borrowed to detect and characterize gamma-ray photons and allow scientists to observe the universe. Since gamma rays are expelled when black holes are formed these telescopes offer scientist a view into this mysterious world and essentially creation. One such telescope currently viewing black holes is the SWIFT, which scans the universe for high energy radiation expelled from a supernova, but what is supernova? Supernova is when a red giant runs out of nuclear fuel and collapses under its own gravity (Thompson, 2009). What remains is a black hole. Black holes are usually only a few times heavier than our Sun since the explosion has blown much of the stellar material away (Marel, 2005). To understand black holes one must understand the power of gravity. According to Einstein, “space gives gravity its pull”. When considering the vast amount of space in the universe you can easily see why gravity is a force to be reckoned with. Under the pressure of gravity the star explodes sending a shockwave through the galaxy which rips time and space. Nothing can escape a black hole, even light, but when matter becomes swallowed by the mammoth......

Merill Lynch

...particular case study we find that Merrill Lynch has introduced a new client relationship technique called the Supernova at the Merrill Lynch’s Indianapolis offices. This practise was implemented on a trial basis and generated a positive and vibrant response between the financial advisors (FA’s) and their customers. But on the flipside it was continuously challenging the traditional ways of dealing of a relationship by a FA with its client party. The concerned person here in this case is in a dilemma whether to apply Supernova in Merrill Lynch with a larger perspective. SUPERNOVA Supernova was the name given to new way of relationship managementintroduced by Merrill Lynch’s Indianapolis offices. Supernova was invented by Rob Knapp, head of Mid West Dist office who’s “Customer Satisfaction” ranked last among 32 dist in country in 1995. The Supernova Model is a client service, client acquisition, and practice management model that drives an explosive acceleration in revenue and client satisfaction by capitalizing upon the 80/20 Rule. It was first implemented by financial advisors at Merrill Lynch under the leadership of FA Rob Knapp. Thereafter it became more popular in the finance industry. The advisor implementing Supernova can prove the benefit of this model while creating a better experience for your clients and significantly growing your business at the same time. Supernova was required at Merrill Lynch since the Financial Advisors hardly contacted their clients......

Black Holes and Their Mysteries

...Hawking claiming that “trillions of black holes were produced in the Big Bang, with some still existing today.” The main theory for larger black holes, the stellar black holes is that they are formed as results of super nova explosions. There are two types of super nova explosions. The first type is when a giant star, of or over, nine solar masses “run out of hydrogen and helium fuel at its core,” but still have enough mass and pressure and produces carbon. Once the star’s core reaches a certain mass it will overwhelm it self and implode. The second type of supernova is formed when a white dwarf star accumulates gas from a companion star. Eventually the white dwarf star becomes compressed. It will ultimately “set off a runaway nuclear reaction inside, that eventually leads to a cataclysmic supernova outburst.” In other words some black holes are formed when massive stars go through supernova explosions. The supernova compresses stars over nine solar masses into extremely small volume of space and this is the reason why black hole gravities are so strong, strong enough to trap light. A black hole is composed of many parts. The point in the center of black holes is called a singularity. At a certain distance around the singularity the gravity will be strong enough to trap everything, light included. This is called the event horizon, also known as the point of no return. A general misconception is that people think the black hole just keeps on sucking everything in......

Insecticidal Property of Acacia Seeds and Bark for Termites

...gas will pull away, forming a shell of gas known as a planetary nebula. | | Scenario 2: | White dwarf The other scenario is that the star will continue to shine through the fusion of helium nuclei, in the triple alpha process. The star is now a white dwarf, and further contraction is prevented by the repulsion of electrons in the core. | | Supernova Very heavy stars will continue to fuse heavy elements in order to produce more energy. However, once iron is formed, it cannot be fused to make more energy since it has such a high binding energy and is therefore very stable. The core will collapse under gravity and huge amounts of gas on the surface of the star will explode out. This star is now called a supernova. | | Neutron Star After a supernova explosion, the iron core of the star may be extremely heavy, and the force of gravity may be extremely large. It then becomes a neutron star, where the repulsion between neutrons stops the contraction caused by gravity. Neutron stars consist of matter that is 100 million times denser than white dwarf matter. | | Pulsars A neutron star may spin rapidly after a supernova explosion, and it may emit two beams of radio waves, light, and X-rays. These beams radiate in a circle because the star is spinning, and it appears that the star is pulsing on and off. Thus, it is given the name Pulsar. Black Holes Neutron-neutron repulsion can only counteract the force of gravity if the core of the dead star weighs less than three...

...body, called a white dwarf, with about the same diameter as that of Earth. The maximum mass of a white dwarf (the Chandrasekhar limit) is 1.4 M. * Explosive hydrogen fusion may occur in the surface layer of a white dwarf in some close binary systems, producing sudden increases in luminosity that we call novae. * An accreting white dwarf in a close binary system can also become a Type Ia supernova when carbon fusion ignites explosively throughout such a degenerate star. High-Mass Stars and Supernovae * After exhausting its central supply of hydrogen and helium, the core of a high-mass (above 8 M) star undergoes a sequence of other thermonuclear reactions. These reactions include carbon fusion, neon fusion, oxygen fusion, and silicon fusion. This last fusion eventually produces an iron core. * A high-mass star dies in a supernova explosion that ejects most of the star’s matter into space at very high speeds. This Type II supernova is triggered by the gravitational collapse and subsequent bounce of the doomed star’s core. * Neutrinos were detected from Supernova 1987A, which was visible to the naked eye. Its development supported theories of Type II supernovae. Neutron Stars, Pulsars, and (perhaps) Quark Stars * The core of a high-mass main-sequence star containing between 8 and 25 M becomes a neutron star. The cores of slightly more massive stars may become quark stars. A neutron star is a very dense stellar corpse consisting of closely packed neutrons...

Is Strategy an Essential Component of Management?

...been focusing on the argument that strategy is needed within organizations in order to set their direction and to compete with other competitors, however, some has also pointed out that the absence of strategy can be considered vital in certain circumstances (Mintzberg 1987b). First of all, the definition of strategy should be clarified. Many works have been developing a view of strategic management which is focusing on ways that corporations develop their goals and direction. Chandler (1962, p.834) defined strategy as “the determination of the basic long-term goals and objectives of an enterprise, and the adoption of courses of action and the allocation of resources necessary for carrying out the goals.” On the other hand, Mintzberg (1987a) has observed and presented five definitions for strategy. They are: plan, ploy, pattern, position and perspective. He pointed out that most people consider organizational strategy as rational plans which are extensively simulated and well-coordinated as well as managed. However, he argues that strategy as a plan can also be a political ploy. For example, a kid may have a strategy to get over a fence, just as an organization or corporation may have one in order to capture their potential market. When strategy is a ploy, the kid may draw a bully using the fence. Likewise, an organization may discourage their competitors from unfavourable actions by threatening them. Strategy is not only plan; it is also a pattern, consistent in......

Problem of Evil

...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 asked him how to reconcile the destruction of an entire civilization with a merciful and loving God. His answer: that ‘‘God has no need to justify His actions to man,’’ is not accepted by the others, who say that the random destruction of worlds is further proof that there is no supreme being, that ‘‘the Universe has no purpose and no plan.’’ The narrator has learned, but not yet revealed, that the supernova was the Star of Bethlehem, which heralded the birth of Christ....

The Star Info

...inhabitants may not be all that important in the cosmic scheme of things. Religion, and in particular religious faith, are central themes in “The Star.” The narrative is the interior monologue of the central character, a Jesuit astrophysicist. He is aboard a star ship on a mission to investigate the causes of a supernova in a distant galaxy. He and the rest of the crew discover the artefacts of a highly developed civilization, carefully preserved on the only planet that remains in orbit around the 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. Knowing that all life would be wiped out when their sun flared into a supernova, this race of sentient beings left a record of who they were and what they accomplished. The pictures, sculptures, music, and other relics of a very humanlike race doomed to destruction depress the crew and investigating scientists, who are far from their own homes and lonely. What the narrator has learned but not yet communicated to the others is that the supernova that destroyed this civilization was the Star of Bethlehem, which burned brightly in the sky to herald the birth of Jesus Christ. His discovery has caused him to re-examine and to question his own faith. Here are some things to keep in mind as you read. o The main character in this story is a Jesuit......

The Mcdonald Observatory

...was then the second biggest telescope in the world. Two other telescope note mentioning are the Harlan J. Smith Telescope (named after once director of the observatory, Harlan J. Smith), and the Hobby-Eberly Telescope (known to be the fifth largest telescope in the world). The Hobby-Eberly is arguably the observatory’s most prized possession. This powerful telescope specializes in spectroscopy which enables astronomers to get a glimpse at stars, planets, and galaxies located light-years away. One ongoing project at McDonald’s is observation of supernovas. Such events are sudden and therefore require the right equipment. Firstly, the astronomers use one of its smaller telescopes to identify newly exploded stars. Then they use the Hobby-Eberly Telescope to gather images and data of the stars dispersed remains, such as its brightness and composition. It is collected data like these that continues to give insight on the cause of the supernova phenomenon. Apart from its telescopes, the observatory is equipped with many other instruments that improve the quality of research they are able to perform. Such instruments include spectrographs which, when attached to telescopes, allow astronomers to perform a host of tasks such as capturing light from the stars, and separating it into its spectrum. The observatory also has different filters that allow them to block out light of different wavelengths so that they can observe the different colors separately. Many have come to believe......
