Abstract
VLBI techniques were used to monitor the milliarcsecond-scale continuum structure of the E/S0 galaxy NGC 3894. The resulting VLBI images span 15 yr and provide morphological and spectral evidence for twin, parsec-scale jets emerging from a synchrotron-self-absorbed core. Analysis of the twin-jet kinematics requires that the jets be both mildly relativistic (v ~ 0.3c) and oriented well away from the line of sight (θ ~ 50°). Slow jets could be deflected or disrupted, so evidence for such processes is examined. A large viewing angle could influence the galaxy's nuclear properties at other wavebands, and those properties are explored.
