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.

This VST image shows a cloud of gas and dust, shaped like a cosmic bat. The intense red glow comes from hydrogen atoms ionized by the intense radiation of young stars within the cloud. The most prominent objects here are RCW 94, which represents the right wing of the bat, and RCW 95, which forms the body, while the other parts of the bat have no official designation.
