This image is a comparison chart of the largest stars observed in the universe so far. The sun is represented by a single pixel. This image does not include the recent discovery of the star R136a1, which is 265 solar masses. As a comparison, VY Canis Majoris, the largest star shown in this image, is only 25 solar masses.
