Twinkle twinkle little star
If you catch yourself looking up at the night sky on a clear night you will see a bunch of stars in your field of view. Upon more careful observation you notice that some of these stars twinkle, or glimmer in the sky. What causes this effect? Why do stars do this and how can we explain it? Let's look into why we experience this eye catching phenomenon and what causes it.
It's all about the atmosphere
The twinkle effect we see from stars is actually not caused by the stars, as the light they shine flies straight towards us from its point of origin. Instead what causes that glimmer effect is the turbulence of the atmosphere of Earth. When the light from a star reaches our Earth's atmosphere it gets slightly bent sometimes which causes that to
This idea of having the light bent when it hits our eyes and gives off the illusion of the twinkle is something we as humans are fascinated with. Optical illusions mess with our perception of the sense of sight, which is exactly why when we find twinkling stars and other various tricks interesting because it seems out of reality in sorts. Have you ever noticed how on a hot summer day if you look
There are so many fascinating things the universe and space have to offer, and the twinkling star phenomenon we ask frequently about is just one of many. I will probably be writing more articles soon about more strange and amazing things we see and learn about in space, but for now I believe that this question that has been asked many times can finally be put to rest. It's not the light from the star, but the atmosphere of Earth that messes with our perception and therefore we get that effect.
