Why do streetlights in the distance twinkle like stars, when the ones nearby seem to glow consistently?
The air in between you and the street light is a moving mass of uneven temperature. As the light moves through it, it gets bent which causes the twinkling effect. The same thing is going on with stars.
The Short Answer
The air in between you and the street light is a moving mass of uneven temperature. As the light moves through it, it gets bent which causes the twinkling effect. The same thing is going on with stars. When the light is closer there is less air for it to move through and so it gets bent less.
