This emoji doesn't just depict a starry night, but our own galaxy, the Milky Way. That's why it often appears when discussing grand-scale topics like "space" or "infinity." It's also used when one is deep in thought.

Scientifically, it's the massive cluster of stars our solar system belongs to, but culturally, it's seen as a symbol of dreams and hope. In the Eastern folktale of "Gyeonwu and Jiknyeo," it serves as the backdrop for the magpie bridge. Perhaps for this reason, the emoji is also used to express a wistful love or a fateful encounter.
