Caption: This visualization is a three-dimensional model constructed using data from Chandra, Spitzer, and ground-based optical telescopes. Scientists determined the positions of the different telescopes, represented by the various colors represent, using the Doppler effect. That information was then put into a medical imaging program adapted for astronomical use before commercial software was used to create the final visualization. This is the first time such a multiwavelength three-dimensional model of a supernova remnant has been created.
