Recent findings suggest that the centers of most galaxies (including our own Milky Way) harbour supermassive black holes over a million times more massive than our sun. Associated with many of these are extremely energetic and collimated outflows of relativistic plasma that can be studied in detail by modern astronomical observatories. In particular, Very Long Baseline Interferometry (VLBI) techniques now routinely provide images of these jetted outflows with a resolution roughly one thousand times better than that of the Hubble Space Telescope. I report on the results of an eight-year long VLBI program to monitor jet activity in over one hundred active galaxies, and discuss a new follow-up project that will address many unanswered questions regarding the complex magnetic field structures found in relativistic jets.
