Comparison Between Novas And Supernovas

1272 Words6 Pages

Introduction The topics that will be explored in the following essay are Novas and Supernovas. In relation to the scope of the course Novas and Supernovas are one of the less obscure concepts for a lot is already known about them. Plus, they are not the hardest concept to understand for basically they are celestial explosions, and if there is anything the masses understand it is explosions. Novas and Supernovas are a part of Strange Science for the full understanding is not yet proven. As only base studies can be done for as the light from them has traveled a vast distance, if one was to send a probe to study them, the explosion would have dissipated by the time it arrived. My name is Andrea Phillips and I am a fourth year Interior Design …show more content…

A Nova is a cataclysmic nuclear explosion on a white dwarf's surface in a binary star system, which causes a sudden brightening of the star, sometimes million times brighter then normal. (Nave, 2012) The gas exploding can occur many times and differing amounts of reaction. Whereas a Supernova is a violent explosion of a star that produces light as bright as billions of normal stars. It also produces heavy elements, such as iron and nickel during their explosions. (Garner, …show more content…

(Garner, 2015) Foley first thought that the young stars had settled into their "final resting spots". So he sent out to determine how fast the stars were traveling before the explosion took place. What he discovered was that they moved at about the same speed as stars that have been tossed out of our Milky Way central black hole, at more than 7 million kilometers an hour. So Foley turned his attention to the aging galaxies in the area of the speeding supernovae confirming that many are massive elliptical galaxies that were merging or had recently merged with other galaxies. Foley hypothesizes that a pair of black holes in the merging galaxies provided the gravitational pull to push the white dwarfs into intergalactic space. Eventually, the white dwarfs get close enough together that one starts with process to become a Supernova. The time it takes for one of these ejected stars to explode is relatively short, about 50 million years. Thus, exploding sooner then scientists expected. (Garner, 2015) However, there is still more to discover such as why these young Supernova explosions are unusually weak. Producing mainly calcium during there explosion, and far less of the heavier elements. So, more investigations will have to be done, to discover more about this topic as is true with many

Compare “mechanical” and “chemical” explosions. Mechanical explosions are explosions caused when a vessel or container bursts as the result of internal pressure from expanding gasses while chemical explosions are caused by high-pressure gasses produced by chemical reactions involving liquid, gas or solid fuels. 7. Define “narcotics”. Narcotic can be defined as a general classification of drugs primarily used as painkillers or anesthetics.

In this zone, in light of the high temperature, almost the majority of the matter present is vaporized to shape a gas at to a great degree high weight. A sudden overpressure, i.e., a weight far in overabundance of climatic weight, proliferates far from the focal point of the blast as a stun wave, diminishing in quality as it ventures. It is this wave, containing the majority of the vitality discharged, that is in charge of the significant part of the dangerous mechanical impacts of an atomic blast. The subtle elements of stun wave engendering and its impacts change contingent upon whether the burst is noticeable all around, submerged, or

To support his findings, many scientists researched this only to find that methane hydrates do exist, in a frozen state, hundreds of meters below the oceans floor. In 2014, three large craters have been discovered in Siberia by the scientists and researchers of TIPG in Russia, to whom they ought to believe that these craters were caused by a large underground explosion. They believe that this area has great similarities with where the Bermuda triangle is

Chemical explosions are one of the coolest things on the planet. A chemical explosion is the sudden, loud, and violent release of energy that happens when something breaks apart in a way that sends flying around(Explosion).

The Atomic Bombs explosive power is the results of a sudden release of the energy from the splitting, or fission of the nuclei of the elements such as plutonium or uranium. On July 16, 1945, at 5:30 a.m. at the desert of New Mexico 100 miles south of the city Santa Fe, The Trinity Test took place, the test is the event where the very first atomic bomb detonated. Scientists distanced themselves to observe as the cloud of mushroom rise 40,000 feet into the sky with blinding lights and created the cataclysmic detonation of 20,000 tons of TNT. When the atomic bomb detonated atop of the tower it was staged at, bright light and burst of heat followed with a wave of sound in the valley echoing created a mushroom cloud and a ball of fire that completely

The Photon Grenade Launcher was an interesting tactical device that “is a mortar-style weapon that fires spherical photon grenades the size of tennis balls” (Kelly). The exact chemical makeup and breakdown of the grenade is unclear and in the Original Series episode “Arena”, it is shown to have extremely effective devastation. This “little jewel” appears to be a miniature nuclear warhead with a bit bigger than its bark. The explosion Kirk creates is vastly expansive and the sight is exceptionally bright, suggesting a critically intense heat. It seems to be a photon explosion, the entire screen flashes white, and the weapon proves effective, causing an enemy retreat.

I hope this letter finds you well. It has been a while since I have last heard from you. Mom and I miss you here in the home front and we are waiting for the day the war finally ends and you get to come home. While thinking about how hard you and the other soldiers are fighting for us and our country, we wanted to find things we can do on the home front to make things better for when you all return. I know it must be extremely difficult in the war front, but I want you to know that all of us here are doing everything we can to help our nation win the war and bring our troops home.

From doing this paper I have learned the process that every firework must go through in order for it to glow in the sky. I learned that the excitement of electrons and thereafter release of energy creates the light in the stars launched into the sky. There are three different classes of fireworks, sparklers, firecrackers, and aerial shells. The amount of energy emitted is specific to the element or salt sent into the sky, and the amount of energy determines the color of the light emitted. Gunpowder is used to propel the firework into the sky because it creates a decomposition reaction that produces a greater amount of pressure.

Inside was a naval gun containing two uranium-235 particles that could be fired together to form the ‘supercritical mass’4, which triggers the atomic explosion. When the bomb detonated, Fireballs, Shock Waves & Air blasts and Radioactivity were the three destructive energy sources formed. Due to air absorbing heat, the fireball swells to an approximate 410m diameter with a temperature of 300,000 oC. The bright orange glow that creates the initial mushroom cloud shape was the fireball and it’s emitted thermal rays causing the ‘temperature on the ground near the centre to reach 3000 - 4000 oC’5. 50% of the energy was the shock wave which travelled 11km in all directions, destroying the city and transferring radiation across the city.

Humans have often wondered how the universe developed into what it is today. For centuries, it has induced religious and scientific discussions and debates, leading famous scientists to trying to discover the enigma which the development of the universe is. One of the most accepted model to represent the evolution of the universe is the big bang theory. “It is an attempt to explain how the universe developed from a very tiny, dense state into what it is today” (Strickland, 2008).
