“Twinkle, twinkle little star how I wonder where you are?” A famous line from one of our favorite nursery songs but the tricky question is: are stars really twinkle? Several researches occurred for this simple to hear yet systematical question to answer. In the end, the answers are within our reach.
Research shows that turbulence occurs in the atmosphere that lets the stars to appear twinkling as their lights appeared to be scattered that are most observable at cold nights when air current rises from ground. Stars that are somewhat near from earth are less affected because their lights pass through thicker portion of earth’s atmosphere. Hence, with the fact that stars are really far from earth most often it only appear like dots making those stars prone to twinkling effect.
Stars do ‘twinkle’ as we see them from the large scale of air and humid. Those air molecules which are almost 10 centimeters freely move within the sky. These sheets of air seem to be lenses where starlight bends known to be the process of refraction similar to the effect of mirage; vapors are more likely moving as a wave.
Likewise, these sheets of air are actively moving across the atmosphere making the effect of refraction towards different directions and when those star lights bend we can only see that flickering lights because we can’t see the motion as our eyes capacity is limited.
Besides whether the stars really twinkle or not, it doesn’t matter at all. The happiness and the inspiration that stars bring to us, making our wishes come true and letting us dream for our brighter future is the most wonderful view way up high. The superstar.
