![The image shows NGC 1866 superimposed with a false color image from the MUSE data cube, where the ionized shell of the planetary nebula Ka LMC 1 is seen as a red ring. The grayscale insets illustrate the different size of the ionized shells of singly ionized nitrogen [N II] and doubly ionized oxygen [O III]. The magnified Hubble image near the center of the ring reveals the presence of a pale blue star -- most probably the hot central star of Ka LMC 1. Image credit: AIP / M.M.
