Energy Star

The life and death of a star is both interesting and complicated. The formation of a star might not be as simple as you think. Some stars actually fail to form big enough to ever be seen. You might also believe that a star will shine forever. However, stars can also lose their energy, causing them to become other types of formations. Stars can be complex anomalies that can end up in several forms including neutron stars, brown dwarfs, and white dwarfs. Star formation is a rather simple process

a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. At 10-35 to 10-33 seconds a runaway process called "Inflation" causes a vast expansion of space filled with this energy. The inflationary period is stopped only when this energy is transformed into matter and energy as we know it. After inflation, one millionth of a second after the Big Bang

Stars change dramatically throughout their existence, due to the forces of gravity, in a process called stellar evolution. Stellar evolution describes how stars transform over time, from birth, through life which includes growth, and ending in death. This process can take billions of years, although the time scale depends on the mass of the star. Luminosity also plays a role in the evolution of a star. Stars begin their life cycle as molecular clouds. Some event, such as a shockwave or collision

explosion of a massive star. For a star to explode as a type II supernova it must be several times more massive than the sun. it is estimated that their mass must be at least 8 times greater than that of the sun, but no more than 40-50 times the suns mass. Stars generate energy via nuclear fusion of elements. Stars of the magnitude great enough to become type II supernovae possess the mass needed to fuse elements that have an atomic mass greater than hydrogen and helium. The energy generated by these

Stars Introduction Those stars in the night sky seem small and tiny, but up close they would be millions of times larger than the Earth. Stars are the most recognized astronomical objects and are the building blocks of the galaxies. These luminous spheres made of plasma are responsible for the creation of heavy elements like carbon, nitrogen, and oxygen. They were among the first objects in the early universe. Most of the elements found in the human body originated in stars, this means that we

Moodle assignment 1. Define star, constellation Star: A self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures. Constellation: An arbitrary formation of stars perceived as a figure or design, especially one of 88 recognized groups named

Stars are born, grow old, and die, at rates that are related to their mass and any external pressures acting on them, similar to the life-cycle of all living things in the universe. The process in which stars change dramatically throughout their existence is called stellar evolution and can take millions to billions of years. Stellar evolution describes how stars transform over time, from birth, through life, which includes growth, and ending in death. Fusion, the force that generates energy, is

destructive explosions. Stars, through their violent birth to their even more violent death, manufacture the elements necessary for life. These giant balls of superheated gas begin their lives as nebulas, slowly evolving into the magnificent lights we see burning in the night sky and eventually dying by gravity, the same force that helped create them, scattering the plethora of elements they created

composed of billion of stars of all ages, sizes and masses. A common stars, like our Sun, constantly gives out small amounts of X-ray radiation, and larger burst of X-rays during a solar flare. Along with our Sun, stars shine as a result of nuclear reaction that happens deep within their core. Causing chemical reactions that converts light elements into heavier ones and while releasing energy in the process. Energy from the central region provides pressure to keep the star from falling apart under

do with ultraviolet light and the formation of new stars. The scientific context of this paper relates to the topic of astrophysics through the fact that it involves stars and the light spectrum. This topic is worthy of investigation because it is important to know how old certain stars are in order to understand the universe. The formation of new stars can be studied by using ultraviolet light because of the large amounts of energy that new stars emit and the fact that each galaxy appears differently
