star mystery :
worm of the sky :
to the east a star arises that ... when it flickers in the sky looks
one side red the other blue it wises around the sky red and blue shifting around White
why does this star flash red blue and green ?

stars are very far away and that light u see has been traveling through space for maybe decades now and its passed through clouds of dust and a bunch of stuff. That makes the star twinkle and gives it colors. Also, stars are not white(unless they are white dwarfs, but those arnt really stars or they are really really big and hot). Almost all stars have a color to them. These can be blue, red, yellow, orange, or any of those colors inbetween.

The colour changes occur because of an atmospheric effect known as scintillation. Air moving in the atmosphere causes the light coming in to refract, scattering the spectrum of colour in different directions. As the air is constantly moving, the colour of the light that reaches your eyes will change from moment to moment creating the illusion that the star is changing colours.
If you were above the atmosphere, you would see the colour as a solid point of light that doesn't change colours.

Stars do indeed appear as a certain colour according to the temperature of them, etc.
But if one is changing colour like this, I guess you could say it's twinkling, which is an effect caused by the movement of the air in our atmosphere, which naturally messes with the image that you can see of the star.

The atmospherics break up the light and shift to make variations of RGB colours Red Blue and Green.

Stars generally dont turn colors, the atmosphere of the earth makes them appear to do this. The moisture in the air causes the effect.

It is possible it is an eclipsing binary star, like Algol, with stars of different colours in the star system, But if it is changing colour in a matter of seconds, rather than hours, then it is scintillation.

the star releases vast amounts of gases plus your looking through several layers of the earths atmosphere.
it's hard to say it depends on what the star is composed of.
it could be hydrogen or helium.
one more thing your looking through millions if not billions of miles of space particles.

If it flashes red, blue and green....then definetly it is not a star.....
it possibly is a passing by plane.:)

The color of a star depends upon it temperature, if the color of this star changes, may be the temperature of this one varies rapidly.
