Cassiopeia A 3-D Model: A Star from the Inside Out

Caption: This visualization is a 3-D model constructed from data from Chandra, Spitzer and ground-based optical telescopes. Scientists determined the positions of the different telescopes, represented by the various colors, 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 3-D model of a supernova remnant has been created.
