In 1572, a "new star" appeared in the sky.  The young Tycho Brahe was captivated, and a pioneer for science and astronomy appeared on the planet.  While most people speculated on the "meaning" of the new star, Tycho merely recorded what he saw (with unprecedented accuracy and precision).  Given Tycho's observations and that supernovae are infrequent (for a given galaxy), Tycho's supernova remnant is of immense interest.  Yet, the last study on the expansion rate of the optical remnant was in 1978 (using photographic plates).  In the advent of digital imaging, Professor Winkler and collaborators have acquired an excellent, ripe image set of the remnant spanning three decades.  From these images, I provide the first full map of the expansion of the optical filaments in Tycho's supernova remnant, and this work helps reveal the nature of the remnant shock wave and the environment through which it propagates.
