Story Synopsis
A star can look like it’s blinking, even though it’s shining steadily. This story explains twinkling. Miluna shares that Earth’s atmosphere is made of air that moves in layers. Warm and cool air bend light a little differently. As the air shifts, the path of starlight wiggles, so the star appears to shimmer. Planets usually twinkle less because they look bigger in the sky. The tone is dreamy and simple, turning a bedtime sky question into quiet understanding. Curiosity stories like this help the night feel friendly.

In One Glance
Starlight travels a long distance through space, but near Earth it must pass through the atmosphere. Air is not perfectly steady—temperature differences and winds create turbulence. Those moving layers refract (bend) light slightly, causing rapid changes in how much light reaches your eyes. That makes a star appear to twinkle. Planets often twinkle less because they appear as tiny disks rather than single points of light. The story frames twinkling as gentle ‘air and light’ science.
