The spiral galaxy M81 hosts the closest extragalactic AGN besides that in Cen A that can be imaged with VLBI. Ground and Space-VLBI observations have shown that M81's center consists of a stationary core and a short, jittery, one-sided jet. The jet appears wavy, reminiscent of a helical structure. The central engine of M81 has qualitative similarities to those of powerful AGN of radio galaxies and quasars, and may represent a scaled-up version in power and size of the largely hidden nucleus of our own Galaxy.
