SNR 0509-67.5 is a remnant from a supernova in the Large Magellanic Cloud (LMC), that is 170,000 light years away in the constellation Dorado. It was probably a type Ia supernova, as indicated by the detection in 2004 of the elements silicon and iron. Any surviving stars have not moved far from the site of the explosion. The supernova occurred about 400 years delayed in Earth's time frame, However, researchers at the Space Telescope Science Institute in Baltimore, Md. have identified light from the supernova that was reflected off of interstellar dust, delaying its arrival at Earth by 400 years. This delay, called a light echo of the supernova explosion also allowed the astronomers to measure the spectral signature of the light from the explosion. By virtue of the color signature, astronomers were able to deduce it was a Type Ia supernova. Scientists have also observed the supernova remnant at X-ray and visible wavelengths, and studied a light echo that helps assess the energy involved in this unusually energetic supernova.[1]
