Curves are one of the basic objects of algebraic geometry, and so much attention has been paid to the moduli space of all curves of a given genus. This talk will focus on the moduli space of genus zero stable curves with n marked points, which is a compactification of the space M0,n of isomorphism classes of n points on the projective line. After introducing this space, I will describe joint work with Angela Gibney on explicit equations for it, which lets us see degenerations to toric varieties.
