超级巨星大犬座

This artist’s impression of hypergiant star VY Canis Majoris shows the star’s vast convection cells and violent ejections. VY Canis Majoris is so large that if it replaced the Sun, the star would extend for hundreds of millions of miles, between the orbits of Jupiter and Saturn.

这幅艺术家对超巨星大犬星座的印象展示了该恒星巨大的对流胞和猛烈的喷射。大犬星座是如此之大，如果它取代了太阳，这颗恒星将在木星和土星的轨道之间延伸数亿英里。
