Life Cycle of a Star

2/9/11

           Stars are alike humans in the life cycle. They are born, alive, and die.

Stars are made by gas and dust from all over the space. When they gather, pressure and temperature rises, which creates nucleus reaction, which also creates light. Now, you’re able to see a twinkling star in the night sky.

           A young star makes their light out of hydrogen for long good periods of time. An old star however, doesn’t have enough hydrogen as fuel, so it eventually goes big and becomes red. This is so called a red giant star.

           Each red giant star has different ways of taking ‘death’. A red giant star as big as the sun, leaves planetary nebula and white dwarf in silence. But some humongous stars die dramatically with a loud explosion. Other stars that are five times smaller than the sun, burst and become supernovas, and then become neutron stars. But those of which are five times bigger than the sun takes the first same process till becoming supernovas, but some of them become a black hole.

           Black holes have far too mare quantity than their size, so they suck in basically everything that’s near. Therefore even a light can’t escape. Matters that are scattered all over the outer space from explosion, are being reused for materials for making a new star
