N49 is the brightest supernova remnant in optical light in the Large Magellanic Cloud. The unique filamentary structure seen in the optical data by Hubble has long set N49 apart from other well understood supernova remnants, as most supernova remnants appear roughly circular in visible light. Recent mapping of molecular clouds suggests that this supernova remnant is expanding into a denser region to the southeast, which would cause its asymmetrical appearance.
