Conference Theme: Physics and Chemistry of the Late Stages of Stellar EvolutionOpen Access journalHubble 12 (Hb 12) is a young planetary nebula (PN) exhibiting nested shells. We present new near-infrared narrow-band imaging observations of Hb 12 using the Canada-France- Hawaii Telescope (CFHT). A number of co-axial rings aligned with the bipolar lobes and two pairs of separate H2 knots with different orientations are detected.link_to_OA_fulltex
