The vast Universe.
At the border where the Sky Zone and the Star Zone meet.
A ring nebula, 5,000 light-years in diameter, is slowly rotating.
At the center of the ring nebula lies a Black Hole, surrounded by a cluster of bright Constant Stars spanning about 500 light-years in diameter, with a rotating ring arm hundreds of light-years wide encircling it thousands of light-years away.
Inside the rotating ring arm, a large amount of interstellar material and glowing Constant Stars form a silver-white ring arm that is relatively dimmer than the central area.
From the cosmic perspective, the ring nebula consists of a bright golden light sphere in the central area and a silver-white ring arm on the edge, separated by a dark vacuum zone, with a very simple and clear structure. It's circular and beautiful, as if God drew a circle with a compass, standard and concise, one cannot help but marvel at the wonders of the Universe's creation!
