We have made VSOP observations of BL Lacertae (2200+420) using HALCA and the VLBA on 8 December 1997 at a resolution of 0.6 × 0.3 milliarcsec. The source structures are identified with the core and superluminal jet-components that are seen in VLBA images at 43 GHz from 1996 (Denn and Mutel 1998). Extended structure out to 20 milliarcsec from the core has been detected
