~astro-craze~

I’m so disturbed right now. It has been 2 weeks already that I haven’t go back hometown. Exams and assignments are keeping me busy here in campus life. Really wish that I’m home now, enjoying mom’s meal. As I look out at the sky, STARS are so wonderful..

A star is a massive, luminous ball of plasma that is held together by gravity. There are several different kinds of stars in the sky. Some are very big. A couple have been found that are 100 to 200 times bigger than the sun. At the end of their lives these large stars can stretch themselves out past the orbit of the planet Uranus. Some very old stars are smaller than the Earth. Scientists study stars, and place them in groups based on how they are alike, and how they are different.

How are stars formed? Wondering? Let me tell you..

A star is formed out of cloud of cool, dense molecular gas. In order for it to become a potential star, the cloud needs to collapse and increase in density. Actually there are two ways this can happen: it can either collide with another dense molecular cloud or it can be near enough to encounter the pressure caused by a giant supernova. Several stars can be born at once with the collision of two galaxies. In both cases, heat is needed to fuel this reaction, which comes from the mutual gravity pulling all the material inward.

After the collision, what happens next is actually dependent upon the size of the newborn star. Small stars will never have enough energy to become anything but a brown dwarf. Some brown dwarfs can technically be called stars depending upon their chemical composition, but the end result is the same; it will cool slowly over billions of years to become the background temperature of the universe. The life cycle of a star is dependent upon how quickly it consumes hydrogen.

Star dies too, just like human being. Amazing isn’t it?

Star is said to have reached middle age by fusing hydrogen into helium. Once a star has run out of usable hydrogen that it can convert into helium, it becomes white dwarf.

Searching for all the facts about stars here, made me miss my mom even more.. She calls me her “Lucky Star”. Life’s short, just like the star, it don’t shine forever. I love my mom and I will make her proud of me one day..
