Answer: The star

Explanation:

Stars twinkle in the night sky due to the atmospheric refraction of starlight.
The bending of light rays when traveling from one medium to another is called refraction.
If light travels from a sparse medium to a dense medium, it is deflected toward the normal.
If light moves from a dense medium to a rarer medium, it will move away from the normal.
Earth's atmosphere is made up of many layers.
When light from a distant source (a star) passes through the atmosphere, it undergoes some refraction.
This light from a star seems to sparkle when we finally see it. This is due to the fact that some beams of light reach us directly, while others move away and towards us. It happens so fast that it creates a shimmer effect.
