Lifecycles of stars

  1. Dec 15, 2005 #1
    I'm a relative newcomer to astronomy and am still trying to understand the lifecycles of stars, i think i understand that the begining stages of stellar evolution involve hydrogen atoms being pulled towards a central area of gravity, but where does the gravity come from?

    Gravity originates with the mass. Remember, the clouds are very large.

    http://en.wikipedia.org/wiki/Nebula - no details, but basic information.

    Some information on the size of nebulae - http://faculty.rmwc.edu/tmichalik/PlanetaryNeb.htm [Broken]
