Shining+Stars

Hey my name is Bree. My topic is about Stars in Space. I chose this topic because as we continue to be wasteful of energy and the environment, we are also being wasteful of the stars in the night sky. On this page you will read about how stars come to life, how stars die, and how we, as people, are affecting the night sky.

__**How Stars Are Born**__ The first stars to ever be created in our universe were created right after the Big Bang. Scientists say that gravity acted on small density differences in gases, matter, and mysterious "dark matter" after the Big Bang to create the first protostars. Now the formation of stars takes place in a cloud of gas or nebula. Supernovae are formed when a star is larger than six solar masses and white dwarfs are when stars are smaller than six solar masses. __**How Stars Die**__ Supernovae are one way a star can die. In this form of a stars death, the star explodes and is destroyed but the destroyed star becomes exceptionally bright. Stars that have reached the end of their productive phase and are under the Chandrasekhar Limit (1.4 times the mass of our sun) becom white dwarfs.
