A new galaxy, the Three-Body Galaxy, has been added to the star map with a Centaurus background, accompanied by an empty star track.
This update only includes the image, with no new content. Since I am not a programmer, I can only make small changes like this.
If anyone is interested in adding new planets or other expansions based on this, I am happy to offer help within my capabilities.
Additionally, if you want new galaxies, star orbits, or images, I am more than willing to assist.
Feel free to contact me with any ideas or suggestions (provided I am also interested in them).

Requires the prerequisite mod.

About the Three-Body Galaxy:

The Three-Body Galaxy is from the science fiction novel The Three-Body Problem by Liu Cixin. In the novel, the Three-Body Galaxy is a star system with three suns, which creates an extremely unstable astronomical environment for its planets. The setting of this galaxy is full of complex physical principles and profound philosophical reflections.
