Meaning
A city skyline at night under a dark blue sky full of stars, with lit-up windows in the buildings. It stands for night time, city nights and late hours.
Use it for good-night messages, late-night work, nightlife plans and city photos after dark: “Still working at midnight 🌃 send snacks”. It is calmer than 🏙️ by day and more urban than 🌌. Many people use it simply to say good night.
