Apologies, I didn't thought in the scale. Certainly it is zero related to this study. I read the article that I linked thinking the Voyagers reached a distance far enough to use it as a stereoscopy through two sources, Earth and Voyager, with the Voyager's collected data. And therefore I thought that's what astronomers in general was using as reference to analyze galaxies (in the last decade). After read again such article I keep thinking about how did I reached this process. Apologies again to everyone.
