Description of Stars

Here is what I would like some comments on:

brief overview of the nature and importance of light and other electromagnetic waves.

How stars fit in the hierarchy of the universe

characteristics of stars

Processes by which stars live and die

how the materials are recycled and how this process might be related to the structure of the Milky Way Galaxy and to the origin of the universe.

Need to consider these facts in describing the life cycle of stars:
Stars seem unchanging, but they are not.  Stars are born from the interstellar medium, become main sequence stars, use up sources of energy, and then ultimately die.  During this time, the star can change dramatically.  Then its ultimate fate depends on its mass.
