Star Formations: The Formation Of Stars

Star Formations Every star you see at night in the sky is bigger and brighter than our sun. Stars are born within clouds of dust and gas that is spread throughout most every galaxy. The life of a star includes many stages from nebulas to the mysterious black holes. Stars are responsible for the creation and circulation of heavy elements such as carbon, nitrogen, and oxygen. The elements characteristics are informally bound to the characteristics of the planetary systems that may consolidate about them. The formation of stars is a process. Everything has to start somewhere or at some point. Stars have a starting formation. Nebulae are the starting point, the beginning of a stars life. A nebula is a visible, at night because it more illuminat …show more content…
This is known as the “baby” star. This is the part of a stars life before they make it into the main sequence, the stage where our sun is currently in. The young star can be stuck in this stage for as many years as 100,000 or more ; it all depends on how big the star is. The protostar starts forming when colossal clouds of frigid molecular hydrogen and helium collapse because of conjoint gravity. The spark of the collapse could have been caused by a galaxy collision, or the shockwave of a neighboring supernova. This collapse causes the cloud to break into fragments. These fragments start to grow as more and more molecules start to attach creating a protostar. The new star starts to increase in temperature, because of the switch from gravitational energy to kinetic energy. The start hasn 't yet gone through nuclear fusion making the star weak and unstable. The star starts to mature by continuously growing in mass and temperature till it reaches the state of equilibrium. Once it’s there it’s is considered a pre-main sequence star, but once it starts to acquire energy from nuclear reactions the protostar is now a main sequence star. If they never reach nuclear fusion, then they become brown dwarfs, stars that never …show more content…
Also, the star reaches levels to where it can now have helium converted to carbon. This energy begins to drastically increase the size of the star, resulting in the creation of a red giant. Oddly enough, the color red, which is associated with hot, isn’t really in this case. The color of the star is a result of the surface temperature decreasing causing wavelengths to emit a red color, while the hotter the star is the color would be more blue. Stars don 't spend much of their life in this stage. They only spend about one billion years in this stage, because helium burns quickly. As the helium runs out and the fusion stops, the star expands one more time. Until, it then shrinks again, and the helium flares up, causing the outer layers of the star to drift off in massive clouds of gas and dust. Those massive clouds are known as planetary nebulae. The smaller stars however, don’t result in planetary nebulae, rather they can become white dwarfs. Also, the more larger stars result in becoming a supernova or a black
