Galaxy, Night Sky, Space, Universe
This is a galaxy composed of billions of stars. Among these stars, the solar system and the earth are also included. It should be noted that in the design of this expression, many platforms display it as a starry night sky, with the outline of mountains or hills in the foreground. Therefore, the expression can generally be used to specifically refer to the Milky Way, the galaxy, the night sky, the space, and the universe.
