What causes a star to twinkle?
That is because the atmosphere has moving pockets of warm and cold area. These move back and forth. When a stars light goes threw the atmosphere, it moves back and forth, just like the warm and cold pockets.-Tgmhc
What if stars didn't twinkle?
Unlikely. Galaxies form from stars pulling each other together. If there were no galaxies, it would be indicative of a lack of forces between the stars. Which roughly means no gravity. Which also means no us.
Can visible light go through the Earth Atmosphere?
The atmoshere can stop the gamma ray but the half of the atmosphere that gets hit by the gamma ray will be destroyed. Chemicals in the gamma ray will eat the ozone and destroy the atmosphere leaving the earth unprotected against the suns U-V rays.
Why some stars are twinkling not others?
Stars themselves do not twinkle, what gives the appearance of twinkling , is the light passing through our atmosphere, different layers have different temperature's, this makes the light oscillate, much like in a heat haze you think the road has water on it but it doesn't.
Where is a shooting star in the atmosphere?
"Shooting stars" or meteors are bits of material falling through Earth's atmosphere; they are heated to incandescence by the friction of the air. The bright trails as they are coming through the Earth's atmosphere are termed meteors, and these chunks as they are hurtling through space are called meteoroids. Large pieces that do not vaporize completely and reach the surface of the Earth are termed meteoritesMeteors
Are stars twinkling?
The light passes through our atmosphere; this atmosphere changes all the time. Small changes in density will change the index of refraction, and change the direction of the light; that's what we see as twinkling.
Why are Stars are brighter when they are seen from the moon?
No atmosphere (air) that dims the light from the stars.No atmosphere (air) that dims the light from the stars.No atmosphere (air) that dims the light from the stars.No atmosphere (air) that dims the light from the stars.
When do stars appear?
The light emited by stars can take thousands of years to reach the Earth, because the stars can be located thousands of light years away. Stars viewed from Earth can only be seen at night because the light from the sun creates a glear on the atmosphere.
Without an atmosphere would there be light all the time?
AnswerThe light comes to us from the sun, moon and stars.Without an atmosphere, there would still be light from the sun during daylight hours. The stars are not visible during the daytime because the light from the sun is scattered through the atmosphere and conceals the much fainter light of the stars, so without an atmosphere the stars would be visible both day and night. The moon reflects light to us from the sun, and would continue to do so even without an atmosphere.
Why star twinkle?
As the light from the star travels through the turbulent atmosphere of the Earth it is refracted in a random sort of a way. This results in the observed twinkling.
Why do stars rotate?
Stars appear to twinkle. The density of air affects how light bends as it passes through the atmosphere. When patches of air of different density come between a star and our eyes, we see different rays of light coming from slightly different parts of the star. The constant movement of air in the atmosphere means stars seem to twinkle.

What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
Why do the sun and moon seem to change colors?
When the sun or moon or stars are low in the sky (near the horizon), the light from them has to pass through much more air in the atmosphere than when they are high overhead. The extra passage through the atmosphere changes the color of the light reaching an observer.
Why you have shooting star?
When meteors enter the Earth's atmosphere they experience friction due to collisions with the atmosphere; by the time they reach 50 to 75 mi (80-120 km) from the earth's surface, they have been heated to incandescence through friction and are visible as "shooting stars," or "falling stars." ...
What causes the distortion of the light from stars that mean we see them twinkling?
The twinkling of stars is caused by the light from them being distorted by the earth's atmosphere.
Why do stars twinkle?
Stars appear to twinkle (blink) because the light from them must reach us by passing through the atmosphere of the earth. By doing this, the light will experience some "distortion" (refraction is the physics term) to a greater or lesser degree.We see this because of light's passage through layers of air with differing temperatures, pressures, densities, moisture content and other factors. All of them will have a subtle effect on the light, and it will "waver" a bit so that we get a "twinkle" when we look at the stars. Temperature differences are well known for distorting light, and the "heat waves" we see when objects are viewed through air with differing temperatures in the path of the light are things we can generally recall. On a hot day, air above the heated surface of a dark colored vehicle appears to "shimmer" because of the "heat" rising from the vehicle. Light from the stars came a long way to get here for us to see it, but it is its passage through earth's atmosphere that gives it the greatest difficulty. And we see the difficulty the light has getting through the atmosphere 'cause it just can't stay in a straight line. The small "shifts" the light takes in its travel appear as the "twinkle" of the stars.The apparent twinkling of stars is actually caused by our atmosphere. As light passes through it, it is slightly interfered with. The lower a star is, the more atmosphere its light is having to pass through, so stars nearer the horizon seem to twinkle a lot more than those higher up or overhead.Clouds, heat waves and other distortions in our atmosphere momentarily blocking the view of the star from earth. Stars twinkle because of turbulence in the Earth's atmosphere.Stars twinkle (and planets do not) because stars appear to us only as points of light. For instance, the very nearest star (other than the Sun) presents no bigger a disk to us than a dime would at a hundred miles away. The tiny aperture means the stream of light is easily perturbed by motion in the atmosphere, generally caused by rising heat. In space, stars do not twinkle.
