FC: Didn't anyone teach you not to read people's diaries???

1: Dedicated to the Big Bang, who gave life to all of us...

2: I just became a star and I'm a little disoriented. As far as I can tell, I'm a ball of gas and dust. I got that way because gravity pulled me into a sphere. | I think that's called nuclear fusion. As I get denser, I can feel my hydrogen changing to helium...

3: Happy Birthday to me!! I am a main sequence star. | There is energy being generated in my core while while my hydrogen atoms fuse into my helium atoms. This is releasing a huge amount of energy. My friends say I won't change size unless I run out of hydrogen atoms.

4: Yes! I am now in the third stage of my life cycle. I lost my hydrogen and I expanded and cooled. | After a while, the loss of hydrogen made my center shrink. My atmosphere got really big and cooled. | I am now one of the lucky stars that can call itself bigger than the sun!!!I am...


6: I know I am in the final stages of my life as a star. I am a white dwarf. I am small, but still hold heat. I'm just a leftover center of an old star. I have no hydrogen left and can't generate energy without it. The good part is I can still shine for billions of years before I cool completely.
