Star Life Cycles

Length: 4 Pages 923 Words

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 Frankli Continue...

The outer layers begin to expand, cool and shine less brightly. The Sun has a surface temperature of 5,500 degrees Celsius. All in a day's work for a star, though. If the core is much greater than 3 solar masses, the core contracts to become a Black Hole. Masses range from a twentieth to over 50 solar masses and surface temperature can range from 3,000 degrees Celsius to over 50,000 degrees Celsius. Sometimes, though the core survives the explosion. The core becomes a White Dwarf the star eventually cools and dims. Nebulae are clouds of dust and gas in space. During the next stage the core is hot enough for the helium to fuse to form carbon. The massive star then becomes a Red Super giant and starts off with a helium core surrounded by a shell of cooling, expanding gas. The expanding star is now called a Red Giant. Their lives, however, depend on their size. If it were any hotter or cooler then it would not be yellow thus causing much difficulty to kindergarteners drawing with crayons, especially ones that Crayola has labeled "sun yellow, and with similar sun references. Consequently that is the cycle of star's lives.
