Flares of gas buring.

I actually did a report on this in my astronomy class at school; it was one of the less painful science classes I’ve ever taken. Here’s an excerpt from the report I did which also covered what astronomers do to compensate for the atmospheric blurring:
Light traveling through space has little if anything to interfere with it. Once it gets to earth, the light has an atmosphere to deal with. The temperature, wind, and other atmospheric complications cause the incoming light from distant stars to refract just a little. As a result, stars seem to twinkle, and when seen through a telescope, the image is distorted; it seems to wiggle around or appear fuzzy. This is similar to looking through heat waves coming off the pavement on hot summer days.

The twinkling effect of stars is owing to their light passing thru their own atmospheres. The planets like venus, mars, jupitar etc. also send their lights, though reflected ones, to the earth. This light appears to be coming steadily, that is , there is no flicker. However, the stars which are suns in their own way, first generate heat and thru it their lights, which has first to pass thru their hot atmospheres before entering into our atmosphere ( after crossing the huge gap of empty space)and finally reaching our eyes. It is the fluctuating temperatures,and thereby the refractive indices of their own atmosphere actually cause the flicker in their light beams which on reaching our eyes give the effect of twinkling.

The light gets bent through the layers of atmosphere, causing the twinkling effect

Atmospheric distortion of the light rays causes them to twinkle on Earth.
Get out of our atmo, and they won't twinkle.

light from the stars gets bent as it travels thru atmospheric layers and our eyes perceive this as twinkling.

stars don't actually twinkle. the stars we see on earth are actually the stars that are exploding. so there are a lot more stars out there that we can't see because they haven't exploded yet.

they dont twinkle there just so hot it makes them white and from a distance they look like that.

Since stars are at huge distance,
& Light doesnot travel as a stream,but in pockets(Streaks)
So there is a gap between two successive POCKETS of light transfer.
1st POCKET of LIGHT ------- GAP--------- 2 nd Pocket of LIGHT
BRIGHTNESS-------------- NOTHING------------- BRIGHTNESS
ON----- OFF----- ON
Continuous ON,OFf,ON process creates TWINKLING EFFECT

they don't. its due to distance variation between different stars & earth. closer ones shine brightly and distant ones lightly
