Stars form when a gravitational force of gases contracts and collapses onto itself. This process is very slow. Scientists estimate that 10 - 20 new stars form each year in the Milky Way. There was most likely a very intense burst of activity when the Universe was young, but over time this has decreased. When two galaxies pass by one another, there are interactions that may cause "starburst" activity, more prolific star-forming activity. (Green Answers)
It takes quite a while for a star to form. There are several types of stars, and all are made up of the same elements. Though it takes wile for it to fom, when it IS form it is beautiful.
