The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

1-2 According to Gray and Larson (2008)‚ a project life cycle typically passes through four stages. These four stages include defining‚ planning‚ executing and delivering. It recognizes that projects have a limited life span and that there are predictable changes in level of effort and focus over the life of the project.
