Star Life Cycles

A detailed Summary of Star Life Cycles

Our world is made up of millions of things. From an atom to a metropolis, and from a comet to a grocery store, the things that surround our lives not only prove to please functional needs but, aesthetic and intellectual, as well. I could go on to list more random things that surround life but I wont.

It is said that one must know their circumstances and situations. It is human nature to be curious about life around us. To be able to perceive things in logical and rational manner is wonderful, but to be able to grasp and hold onto knowledge that is proven correct trillions of light years away from you is truly beautiful. Enter: the field of science.

Humans have been curious with the functional purposes and features of life since our evolution into humans. Many times early humans would be frustrated with science and walk with their heads down. Thus comes in the saying "keep your chin up." When they would look up what would they see? The sky, of course. Thus sparking a new curiosity.

After many innovations in the study of the sky it has been concluded that it is very large (quite possibly the most correctly observant thing in science along with of course Galileo's "Eureka!" in the bath tub, and Ben Franklin realizin

Stars lead very glamorous lives (har har). Their lives, however, depend on their size. Let's look at small stars first. The first stage consists of the star being born in a region of high density Nebula. It then condenses into a huge globule of gas and dust and contracts under its own gravity. Then a region of condensing matter will begin to heat up and start to glow forming Protostars. If a protostar contains enough matter the central temperature reaches 15 million degrees centigrade. During the next stage the star begins to release energy, stopping it from contracting even more and causes it to shine. Next a star of one solar mass remains in main sequence for about 10 billion years, until all of the hydrogen has fused to form helium. Then the helium core starts to contract further and reactions begin to occur in a shell around the core. During the next stage the core is hot enough for the helium to fuse to form carbon. The outer layers begin to expand, cool and shine less brightly. The expanding star is now called a Red Giant. After that stage the helium core runs out, and the outer layers drift of away from the core as a gaseous shell. During the final stage the remaining core (thats 80% of the original star) is now in its final stages. The core becomes a White Dwarf the star eventually cools and dims. When it stops shining, the now dead star is called a Bla
