N49 is a supernova remnant in the Large Magellanic Cloud, a satellite of the Milky Way Galaxy. This supernova remnant is one of the brightest such objects in optical radiation. This image combines optical data (shown in yellow) from the Hubble Space Telescope and X-ray observations (blue) from the Chandra X-ray Observatory. Astronomers say the explosion that spewed the original star’s debris was lopsided, which is why the supernova remnant is asymmetrical.
