Abstract
VLBI techniques were used to monitor the milliarcsecond-scale continuu m structure of the E/SO galaxy NGC 3894. The resulting VLBI images spa n 15 yr and provide morphological and spectral evidence for twin, pars ec-scale jets emerging from a synchrotron-self-absorbed core. Analysis of the twin-jet kinematics requires that the jets be both mildly rela tivistic (v similar to 0.3c) and oriented well away from the line of s ight (theta similar to 50 degrees). Slow jets could be deflected or di srupted, so evidence for such processes is examined. A large viewing a ngle could in influence the galaxy's nuclear properties at other waveb ands, and those properties are explored.
