Summary
Date: The Hubble Space Telescope The universe is mysterious and amazing. The likes of Keplar and Galileo gazed through crude telescopes and tried to analyze the universe to some extent, in fact mankind has tried for several centuries to know what was beyond the boundaries of the earth and that is when the need for space telescopes crept in…

However, even though these ground based telescopes have provided us with extremely valuable information they were unable to detect light that does not reach the atmosphere. Therefore, to understand something that is in space, light-years away from us, we need to study and analyze the different electromagnetic radiations that are emitted and with the rapid surge in technological advancement man has successfully installed telescopes in space which has enable us to see things that was never seen before. The latest scientific ambition of space scientists which has been utterly successful so far is the NASA’s Edwin Hubble Space telescope. The space telescope was launched in 1990 and since then it has helped unravel numerous secrets of the universe and provided researchers with valuable scientific data and photographs of very high resolution which have made space studies far easier than what it had been before. It is perched 350miles above the Earth. So far the Hubble telescope has imaged more than 30,000 celestial objects and taken more than 570,000 pictures (Space telescope Science Institute,p.1) The observatory above the Earth’s atmosphere works all the time to gather data and information about all the different constituents of our Universe, components of the Milky way, galaxies, quasars etc. The high light gathering power of the Hubble telescopes enable it to take space pictures with immense clarity The major elements of the Hubble telescope consists of : mirrors that collect light from celestial bodies, devices used to analyze the images caught by the mirrors, a spacecraft structure that shelters the mirrors and analyzing instruments and solar arrays. One of most renowned images that the Hubble telescope has provided is the image of Supernovas using which scientists have been able to conclude a lot of things. Supernovas are extensively bright objects that are formed when an old star has reached its life’s end and explode in space. This explosion expels most of the star’s material into the space. In the year 2003, with the help of newly installed Advanced Camera for Survey (ACS) on the Hubble telescope the first two supernovas had been discovered. This was primarily done by observation of the Hubble Deep Field North with the wide field camera of the ACS that was installed. These observations were taken in May, 2002 in bandpasses F775W and G800L. The F775W bandpass was meant for 2 orbits while G800L was for 3 orbits. A subsequent observation was made for 3 orbits in the F850LP bandpass. The observation and the images that had been recorded were initially analyzed by the Space Telescope Science Institute. The Institute helped to analyze the images and reduce them down for a more specific observation and further reduction was done with the Apsis GTO data which rejects cosmic ray, detects defects and corrects the image geometrically. After the images had been reduced down, the presence of two highly bright objects were seen that was not present in the 1995 data. These two objects were designated as SN 2002dc and SN2002 dd and were categorized as 1A supernova subtype (Blackeslee et al, 2003). A similar detection was done in the year 2004 where researchers found 16 new supernovas of subtype 1a with the help of the Hubble space telescope. During the GOODS SCA treasury program observation were ...Download file to see next pagesRead More

...? Hubble Telescope Submitted to, Submitted By, of the Submitted on, [December 1st, INTRODUCTION The space and everything it holds are unimaginable boundaries. For long man has been in pursuance of finding out what the space beyond the Earth’s skies is actually composed of. Time and again man invented various instruments that assisted in the finding out of what resided in the skies that were apparently unseen to man. Among these instruments one of the most revealing instrument proved to be the invention of the telescope. Its subsequent placement into the atmosphere beyond the Earth’s visible skies opened new horizons of information regarding the universe. The Hubble telescope was the first...

...at that time. In the autumn of 1913, Hubble was hired by New Albany High School (New Albany, Indiana) to teach Spanish, Physics and Mathematics and to coach basketball. His popularity as a teacher is recorded in the school yearbook dedicated to him: "To our beloved teacher of Spanish and Physics, who has been a loyal friend to us in our senior year, ever willing to cheer and help us both in school and on the field, we, the class of 1914, lovingly dedicate this book." (“Edwin Powell Hubble - The man who discovered the cosmos”) After finishing his school term in May 1914, he returned to the University of Chicago and the Yerkes Observatory to finish his doctoral (PhD)...

Explosions
...Explosions This paper looks at five explosion disasters that have occurred in the recent past in the US. While one was not strictly an explosion it has been included in here because of the nature of its cause and the similarity of its underlying causes to the other four. We look at the Imperial Sugar explosion of Port Wentworth, Georgia on February 7, 2008; the BP Texas City Refinery explosion on March 23, 2005; the gas tank explosions at Southwest Industrial Gases on July 25, 2007 in Dallas, Texas; the CAI inc. chemical fire on November 22, 2006 at Danvers, Massachusetts; and the Bastian Plating Company’s poisonous gas disaster on June...

...of these explosions carry an agenda which requires the Government to oblige to a particular need of the terrorist organization. In many other cases, these terror activities are carried on in order to scare the public and to announce the coming of a new terrorist organization. Thus, there is no specific reason for the terror activities and explosions that are carried out on a global level. A careful stance needs to be maintained on this area in order to prevent further loss of life and property. Ukraine is the latest nation to get affected by the bombing and explosion spree. The civilians and the Government of Ukraine were stunned at the ruthless bombing in some of the...

Supernova Shockwave The supernova shockwave also called SN 1987A is the consequence of a stellar explosion which was the brightest the world had seen seventeen years ago. For months it blazed with the intensity of 100,000,000 suns and now even though it has been ages, there is a light that shines which is fainter but still bright. There are bright lit rings of gas that gives the appearance of pearls that are produced by the shock wave and they hit the ring and get absorbed. The inner region of the ring also heats up and its...

Supernova
...Number] Supernova Supernova is when a star that can’t handle its nuclear fuel and thus, explodes ina bright light which increases its brightness greatly. During this event, the brightness of the explosion causes enough light to outshine the entire galaxy of millions and billions of stars. Supernova causes the brightness of light leashed through cosmos, and eventually it is the death of a star with an explosion. These happen in two ways: when stars are out of nuclear fuel and they can’t handle their own weight due to lack of pressure, they collapse. Secondly, when matter piles up on the core of a dead star and an explosion takes place...

...which is most likely thermonuclear explosion of white dwarfs these makes them useful candles. Type Ia supernova have proven to be excellent distance indicators when well treated. Although they have virtues that are linked to standard candle, they are not standard candle. Combined with the high luminosity of objects which make them detectable out of redshift near 1, they can be used to measure cosmological distances and provide determination of acceleration of the universe. The assumption that is made is that supernova expands in a spherical symmetric manner. It is unlikely that supernova Ia will provide genuine and detailed results of the peculiar velocity field just...
