A star is a luminous big thing shaped like our sun that are all around in our galaxy. The reason they call it a star life cycle is because the star goes through different stages. The star goes through ten stages and at the end it usually explodes.The stars form from a stellar nebula by interstellar clouds. The interstellar clouds are mostly made of hydrogen but the nebule is called a molecular cloud. My star is the very end of a stars life cycle my star happens to be a Supernova. A Supernova is the largest explosion that takes place in space. Supernova’s usually take place in other galaxies but they can be seen from here on our planet earth. We have stars that are 10 to 100 times bigger than our sun and the stars eventually explode overtime. …show more content…
A Red Supergiant star is an aging star that has consumed all of its core’s supply of hydrogen fuel. The reason the planet is red is because the planet got cool and it got the color red. A interesting fact about this star is that they are one of the largest known stars. But these stars are not the brightest in our universe. After the whole Supernova star has exploded the star that comes after that is called a Neutron star. A Neutron star is a mixture of protons and electrons melting together. A Neutron is a city sized stellar object that has 1.4 of the sun’s mass. This star isn’t that big but it can cause a quark star and then that quark star can turn into a black hole. An interesting fact about a Neutron star is that one teaspoon of that star weighs about six billion tons. So as you can see the Supernova is an interesting star. Not only is it one of the brightest explosions that takes place in space but it takes millions of years for its brightness to go fade. Some of the materials we find here on Earth today come from a Supernova explosion. A Supernova doesn’t have to be a certain type of star for it to become a Supernova. An interesting fact about a Supernova is that when the stars core collapse it only takes one second for it to become a

Star Life Cycle

a star's life, it is first a nebula. Nebulas are what's left of stars after massive stars turn into red supergiants and then explode. This massive explosion is called a supernova. A nebula is a big cloud of hydrogen and helium filled gas. These nebulae are the place where all stars are born. The hydrogen and helium are what fuels the star during its life. Every star has a life cycle it must go through depending on its size. Our average sized sun is at the very beginning of its life. Our sun will…

Low Mass Star Research Paper

are two types of stars in the universe; high mass and low mass stars. We will discuss the latter and their life stages. The life cycle of a star is determined by the mass of the star. The smaller a star is the longer its life cycle is. In our solar system we have a low mass star, it is the Sun. Low mass stars are stars that are smaller, cooler and are slower to use their hydrogen, thus allowing this type of star to have a longer life than that of high mass star. The life cycle starts from the collapse…

brief). What forces are opposing one another throughout the life of a star and how do they influence the various stages in the life cycle of a star? Answer: Stellar evolution is the lifecycle of stars. This interesting cycle consist of star birth, the protostar stage, the main-sequence stage, red giant stage and burnout and death. This cycle still has many people amazed and wondering how some forces influence various stages. Stars are born in nebulae. These huge dark, cool, interstellar clouds…

chem final Essay

Ms. Webber Chemistry A 16 January 2015 The CNO Cycle (Carbon-Nitrogen-Oxygen Cycle) Nuclear processes take place when the nucleus of an atom is unstable. Nuclear process happen all around our lives, including medical, industry, energy, military, and space. The nuclear process that caught my eye the most was the CNO Cycle (Carbon-Nitrogen-Oxygen Cycle). This process is vital to life on Earth because it produces a majority of the energy in most stars and a small amount in the Sun. My views on this…

Star Characteristics

Characteristics of Stars The characteristics used to describe stars are size, colour, temperature, luminosity (brightness) and density. Scientists have discovered that the temperature of a star can be estimated by its. Example: Red → relatively cool Orange → warmer Yellow → warmer still . . . temp. of our Sun White → even warmer . . . temp. of Sirius Blue → hottest temperature The brightness of stars can be described in two ways: 1. Apparent magnitude – The brightness of the start as it appears from…

Proto Proton Fusion

Stars, just like our sun, have been undergoing nuclear processes ever since their birth. Initially thought to be a great ball of fire by ancient astronomers (Cain and Cain, 2009), a fundamental process known as nuclear fusion is the sole workhorse behind the life of a sun. This process produces immense amounts of energy comprising of light and heat which, for our sun, essentially sustains life on earth (BBC, 2016). The various nuclear fusion processes along with experiments will be discussed highlighting…
