Storyboard Text

  • Before i was born, gasses were pulled together to form a nebula. As it started to condense under its own gravity it formed a large ball.
  • Once my hydrogen started to fuse and form helium i was born. I then start to release energy and shine.
  • At this point i am an adult star, a main sequence star on the Hertzsprung-Russell (HR) diagram. The HR scale shows luminosity and temperature. I am located in the middle right now.
  • As I have gotten older and bigger, I have been fusing helium into carbon. Now that I am a Red Giant my outer layers are cooler but my core is even hotter.
  • As my helium core ran out, my outer layers started to drift away. These gasses that surround me are a planetary nebula.
  • Now that I am old, I lost 20% of my body and feel weak. I feel my core starting to cool and dim. I realize that I am a white dwarf now, but once I loose my luminosity I will become a black dwarf and die!
