Supernova remnant N132D, combined X-ray and optical image. The shockwave from the supernova is causing the surrounding gas and dust (pink) to glow. The supernova occurred around 163,000 years ago, and was first visible from Earth 3000 years ago. This supernova remnant is 160,000 light years from Earth, in the Large Magellanic Cloud in the constellation Dorado. The optical data was obtained with Hubble's ACS instrument, while the X-ray data is from the Chandra X-ray Observatory's ACIS instrument. The results were published in October 2005.
