We present multi-epoch Spitzer spectra of the well known supernova remnant, SN 1987A. SN 1987A was the first supernova observed by naked eye in almost 400 years and has been intensely studied at all wavelengths with a wide array of telescopes and instrumentation. HST imaging has shown an equatorial ring (ER) spanning 1.6×1.2 in diameter [1]. This ring is believed to be material originating in an earlier stellar wind and mass-loss phase of the progenitor star and is now being heated by the supernova shock wave and is slowly increasing in brightness. Our two epochs of Spitzer observations trace the brightness evolution of the ER and reveal the composition of the ring material and the surrounding local interstellar medium.
