Storyboard Text

  • A star is born in a molecular cloud. The molecular clouds are the remains of a star that previously died.
  • A star is born because the gravity inside clouds is so strong that it pulls materials from the previous star together to make a new star.
  • A star goes through its life by consuming hydrogen and turning it into helium. As shown on an HR graph, it's temperature and brightness will slowly increase as it ages.
  • As the star goes into to its last stage of life, it runs out of fuel and becomes a red giant. This is the part of the star's life where it peals off of the main sequence of an HR graph as it becomes drastically brighter and cooler.
  • Finally after the star runs out of fuel it will explode. This is the part where the star disappears off the HR graph.
  • Some times if the star is large enough and the gravity is strong enough all the materials and makeup of the star will pull into each other until it becomes a black hole.
