Why do the stars twinkle?
Answers:
Stars appear to twinkle because of density fluctuations in our atmosphere. As the beam of light travels from the star to your eye, it passes through the atmosphere of the earth. It is important to understand that the atmosphere is not exactly uniform everywhere. Due to temperature differences and random fluctuations some regions of air will be more or less dense than others. The size of these regions may be as large or a hurricane or as small as some microscopic area (however, in general the smaller the region the less time it will be stable). Because the density of air affects its refractive index, these pockets will effectively act as lenses, slightly bending the light in different directions. Because these 'lenses' are in constant flux, moving and changing size continuosly, the direction in which the light is bent is also changing constantly. The result of this is the twinkling effect that you see. Planets do not twinkle as significantly because they are closer, and thus the 'size' of the light beam is larger causing it to be less susceptible to small-scale distortions in its path.
our atmosphere gives the impression the stars are twinkling to our otherwise untrained eye.
The light from stars enters our atmosphere and is refracted by various atmospheric molecules, thus producing a "twinkle" effect. In outer space, with no atmosphere present, the stars will not appear to twinkle. They will just look light dots of light.
Everybody has to, not just stars.
Its because the light from the star has to pass through our atmosphere.
This makes the star appear to flicker.
If you are in space they dont.
The air bends the light. Ever notice "heat shimmers" on a hot road? That's a similar thing.
I agree with what sparkloom said ..
Just like me, they long to be, close to you. (at least I'm original lol)
Me too
Variations in the refractive index (e.g., atmospheric temperature variations, atmospheric waves) of the atmosphere result in a beam of light (e.g., star light, planet light, laser light) being slightly bent and diffused to the point where the intensity of light reaching your eye changes, which results in the light appearing to twinkle. The stronger the light (i.e., the closer generally) the less the effect.
Thus planet light appears not to twinkle (it does just very little with respect to the base intensity) compared to starlight (whom's intensity is low to start with).
Hope this helps
Stars do not twinkle but they look like they do because of the Earths ionosphere. Each star is a sun like our own so they are burning balls of fire but too far away to receive direct heat. Depending on the angle of the star and the weather it will twinkle more or less. Try looking at a setting star and compare it with a star overhead. Just incase you wonder planets reflect the light of the sun ( like mirrors in space) and do not have light of their own. The Moon also shines like this reflecting light.
they don't its an optical effect, produced when the light hits our atmosphere.
its a bit like heat haze, where things same to move when U see them though the heat haze, when they aren't.
it's one of the reasons the Hubble telescope is so good, as the light it receives is not distorted in any way
just like a rainbow only the light is bouncing off our atmosphere faster than the speed of light
they asume to twinkle due to atmospheric refraction that is bending of light.
