Do all stars twinkle? What causes them to twinkle?

Answer 1

Mainly because our atmosphere refracts light waves and also due to the vast distances the light has to travel.

Answer 2

Yes stars do seem to twinkle, but its nothing to do with the star, and "space dust" (I think that person meant gas clouds in space) would only affect very few. There are a few reasons;

One being that the photons that are leaving the stars, become furthor and furthor apart as they travel through space, try and think of a bunch of balls starting in a bunch and then something in the centre exploded...all of the balls would go in every which direction and as they moved away from the centre they would get furthor and furthor apart. So the photons leaving the stars do the same thing, over billions of kilometres. When they reach your eye they would be a bit separated and that would make them blurry.

Now the main reason is light polution, and out atmosphere. Try and think of where all the really expensive stationary telescopes are placed, they are always very high up, and they are in remote locations away from cities. Light pollution actually makes it harder to see the stars in the sky and if you go out into the country you can actually see a lot more stars, light polution would make the stars seem like they are twinkling a bit and thus the reason to put telescopes in remote locatoins. Now the reason why they put them at high altitudes is because there is less atmospheric interfearence that makes it harder to see the stars. This would also make them blur or twinkle. The higher they put the telescopes the less dense the air will be and the clearer image they get, with less twinkle.

The best example of this is Hubble! lol why would they spend all that money to put a telescope into space. Well for one, it gets a lot clearer images because there is no atmosphere for the photons to get lost in. So yeah Hubbles into orbit so the stars would no longer twinkle. LOL

So after that explanation when your looking through a filter, like out atmosphere it makes ALL stars SEEM like they twinkle. And the high energy photons crashing into the ozone will make our image of the stars a little less clear.

Hope I helped.

Answer 3

Stars seen through the atmosphere of Earth appear to twinkle. Stars seen in space do not - or so I have been told - twinkle.

Answer 4

The only star that does not twinkle is our Sun.
Stars twinkle because starlight comes to us through moving layers of air that surround the earth.

Answer 5

stars do not twinkle. they appear to do so here on earth because of turbulances in the atmosphere. ( for a crude exaple , looking at objects over a very hot surface . you will see objects wavering when actually they dont ) stars are small objects when seen from earth. so they dont have much to waver. they appears twinkling.
PS. some might quote from an ancient text saying that stars do twinkle ( ' twinkle twinkle little star... etc it goes ) but the proponents of this theory were unsuccessful in providing solid evidence so far.
LOL

Answer 6

The twinkling you see is due to our own atomsphere. When in space they don't appear to twinkle, because stars don't, in fact, twinkle. They are just suns, after all, and our sun doesn't twinkle. (Now, our sun--and all stars--do undergo very very slight modulations in the amount of light they emit, e.g., if there is a flare. But these will not be visible to the naked eye, not for our sun, and especially not for other stars. You need serious equipment to see this.)

Answer 7

All stars do twinkle and the cause of this is the temperature of the stars. If the color is blue, that means the star's temperature is cold and if it's yellow or red, it's temperature is hot.

Answer 8

Stars look to twinkle because of the fact the flow of air (often suggested as turbulence) interior the ambience of Earth reasons the starlight to get extremely bent because it travels from the distant action picture star during the ambience right down to us on the floor. this implies that the countless mild reaches us immediately and a few gets bent extremely away. To our eyes, this makes the action picture star look to twinkle. you will see that stars closer to the horizon will seem to twinkle greater advantageous than different stars. this is via the fact there is so plenty greater surroundings between you and a action picture star close to the horizon than between you and a action picture star greater interior the sky.

Answer 9

the stars twinkle due to earths atmosphere

Answer 10

The lightyears makes them "look" twinkle.
Stars are explosion of lights. The twinkle is cause by the distance and the medium that lights travel across the galaxy.

The blink you see is the blink of 1000+ years ago.
