 An international team of researchers from eight different countries has imaged with unprecedented accuracy the newly forming jets of plasma from the core of NGC1275, the central galaxy of the Perseus cluster, identified with radio source 3C 84. Radio images made with an array including the RadioAstron Space Radio Telescope (SRT) and a global array of ground radio telescopes resolve the jet structure ten times closer to the central engine than what has been possible in previous ground- based observations.
 These space-VLBI observations were obtained within the RadioAstron Nearby AGN Key Science Project coordinated by Tuomas Savolainen. 3C 84 was observed on September 21-22, 2013. In addition to SRT, more than two dozen ground radio telescopes, including the EVN, the KVN, Kalyazin and the NRAO VLBA, GBT and the phased JVLA participated in the experiment. First results are now published in Giovannini et al. (2018).

 **Figure:** Radio image of the central parsec in 3C 84 obtained with the space-VLBI array. The half- power-beam-width (HPBW) is 0.10 x 0.05 mas at PA 0o. The noise level is 1.4 mJy/beam and the peak intensity is 0.75 Jy/beam. The radio core and emission features C2 and C3 are indicated in the image.
