  In this thesis I give a new description for the moduli space of stable n
pointed curves of genus zero and explicitly specify a natural isomorphism and
inverse between them that preserves many important properties. I also give a
natural description for the universal curve of this space. These descriptions
are explicit and defined in a straight forward way. I also compute the tangent
bundle of this space. In the second part of the thesis I compute the ordinary
integral cohomology ring from the above description and specify a basis for it.
