The contact invariant, introduced by Kronheimer and Mrowka, is an element in the monopole Floer homology of a 3-manifold which is canonically attached to a contact structure. I will describe an application of monopole Floer homology and the contact invariant to study the topology of spaces of contact structures and contactomorphisms on 3-manifolds. The main new tool is a version of the contact invariant for families of contact structures.
