SNR 0509-67.5is aremnant from a supernovain theLarge Magellanic Cloud(LMC), that is 160,000light yearsaway in the constellationDorado.It displays a clearshock waveshock shellpattern.

It was probably atype Ia supernova,as indicated by the detection in 2004 of theelementssiliconandiron.Any surviving stars should not have moved far from the site of the explosion. 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, allowing scientists to study the initial blast. This delay, called a light echo, 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 atX-rayandvisiblewavelengths, and studied alight echothat helps assess the energy involved in this unusually energetic supernova.
