A Twistor is a pair of two-component Spinors - one transforming in the fundamental representation of SL(2,C), the other in the conjugate representation - which corresponds (via a "twistor correspondence") to a null line in Minkowski space. The space of such objects is called Twistor Space, and provides an important alternative description of many mathematical objects used in physics.
