How do stars twinkle in the absence of oxygen?
Stars twinkle due to the Earth's atmosphere and its turbulence, which causes the light from stars to refract and flicker as it passes through. The twinkling effect is not related to the presence of oxygen specifically, so stars can still appear to twinkle in the absence of oxygen.
Why do the stars glow above?
I'm assuming that the question is "why do the stars twinkle" The light from stars passes through our atmosphere and gets refracted several times due to the varying density of the air. Also, this density doesn't remain constant at each layer. This constantly alters the light wave direction (which gets bent due to refraction) and the luminosity (due to varying density). This gives us an illusion that the star is getting dimmed and brighting up. It is similar to watching the sun through a mirage and it looks as if we are watching it through water. In this case, the hot air is distorting the sun's light. If we are in the outer space, the stars dont twinkle. they just glow.
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.
What causes a star to twinkle?
The twinkling effect on starlight - properly called scintillation - is caused by refraction in the Earth's atmosphere, due to minor changes in density which result from a difference in temperature. As the air is moved by winds, the exact composition changes and this alters the amount of light refracted to an observer; as more or less light is sent to the observer, its apparent brightness changes, and this is what we call twinkling.Stars do not actually "twinkle" (as a general statement). The effect that makes them look like they twinkle is atmospheric disturbance (heat dissipation of the atmosphere) - the same way you can see the image of a tree wiggle if you are looking at it over a road baking in the hot sun. NOTE: Some stars (suns) do 'flash' or 'flare' but these are exceptions to the rule.Light is changed by Earth's atmosphere - and the density of the parts of the atmosphere through which the star's light travels changes quickly.The stars do not actually twinkle, if you were above Earth's atmosphere they would appear to you as small but stable points of light. It is only when seen through Earth'satmosphere that the light is distorted and appears to twinkle.
Does black hole have the highest refractive index?
No. A black hole does not have a refractive index. The bending of light around a black hole is due to gravity, which is entirely different from refraction.

What is the fuzzy cloud around the stars?
Stars appear to twinkle and are fuzzy due to the earths atmosphere
Which stars twinkle the most?
The twinkle comes from atmospheric conditions on earth, if lower in the horizon, then the twinkle is increased as the light has to pass through more atmosphere. Air pollution nearer urban areas also effects the twinkle. No particular stars twinkle more than others, it's mainly due to their position in the sky and local atmospheric conditions.
Why are stars pointy?
Stars appear pointy due to atmospheric distortion when viewed from Earth. The Earth's atmosphere causes light from stars to bend and twinkle, making them seem to twinkle and appear pointy. In reality, stars are spherical in shape like our own sun.
Do stars twinkle?
Not really. A star seems to twinkle because its light all comes from a single tiny pointand has to go through Earth's turbulent atmosphere. Planets don't twinkle, becausetheir light comes from a larger point. And in orbit or on the moon, stars don't either.They do not -so viewing them from space they do not.Only viewing them from Earth do theydo that, due to the atmosphere interference.No, stars really don't twinkle in the sky. The reason that stars seem to twinkle when you look at them is because there is a lot of atmosphere between you and the clouds. This causes the stars to disappear for a fraction of a second and reappear, making them seem to twinkle.No, stars really don't twinkle in the sky.

How are stars made with no gravity?
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
How can you identify stars and planets?
Stars 'twinkle', planets do not. This is due to the proximity of planets, the light from which does not pass through so much dust and vary accordingly.
Which stars wink?
Stars appear to twinkle or flicker in the night sky due to the Earth's atmosphere causing the light from the stars to refract, creating a twinkling effect. This phenomenon is more noticeable when stars are low on the horizon, as the light passes through a greater thickness of the atmosphere. All stars can appear to "wink" or twinkle as seen from Earth.

Why do astronauts in orbit around Earth see a black sky with stars that do not twinkle but see a blue earth?
Stars twinkle due to the scattering effect of earth's atmosphere. In space this is no atmosphere, thus they do not twinkle. The sky is black in space because there is no scattering of light as there is in the atmosphere. The earth appears blue from space due to the color of the gases in the atmosphere, and their reflected light on large bodies of water.
How stars twinkle?
Stars are hundreds or thousands of light years away from us, so they can be considered as point sources of lights. The light rays emitted by these stars enter into the earth's atmosphere and undergoes continuous refraction, because each layer of earth's atmosphere has different density. They go on refracting and the light rays reaching our eyes will be bended like an arc. Thus we see the stars in an apparent position, which is slightly different from the actual position. Due to continuous refraction the amount of light gets fluctuated. We see that the position is slightly altered. This causes the Twinkling effect.
