We are constantly confronted with various events that result from certain features of our world. for example around yourself His return gives us day and night. Thanks to the movement around the sun, we get to see the seasons. in the head question mark These characteristics also play a role in revealing other important events that

For example, in this content, one of the events in question and everyone who likes to look at the sky has crossed your mind at least once.of the stars We are going to clarify the case of ‘looking as if it blinks’. Without further ado, let’s get right to the point.

We see that pictures of stars taken by our telescopes in space are very clear.

The reason for this is the light source in the room and the light source in the room. our telescopes that there is no obstacle between from the source achieving his goal.

So what’s changing on Earth?

Contrary to the above situation, from the earth to the light sources in the sky, as we have just explained, straight away You can’t look.

Because this time, unlike him, between you and the light source, atmosphere comes in. So what exactly does the atmosphere do to the light?

The term we are looking for to explain this is astronomical scintillation. Let’s explain it simply

As we know, the Earth has an atmosphere with several layers. In addition, these layers temperature It is also not balanced.

One layer is usually warmer or warmer than the other. cold but also these degrees of temperature/cold are constant on their own. nonstop it is changing.

With the effect of this, the rays that travel through long paths in endless space are affected in our atmosphere, which is their final destination.

As we said, the temperature of the atmosphere and its movement changes always continues.

For this reason the rays come from outside from the outside it constantly changes course on a small scale until it reaches our eyes. Finally, the ever-changing zigzag a trajectory is obtained.

This situation continues even after the rays reach our eyes.

As a result, sometimes Lake the beam is reflected in our eyes, sometimes less. When more light reaches us, the star that is the source of those rays brighter looks like.

Likewise, when the rays are less focused on our eyes, this brightness diminishing. The result is that the stars he winked resembling.

You experience this situation when you look at the city lights in the distance. The reason is the same

In fact, if you look around or slightly above a burning fire, you can still see this phenomenon.

There too, in the temperature and movement of the air constant changemakes us see objects and objects behind them as if they were floating.

Let’s add some interesting information.

• Flickering stars were initially a nightmare for astronomers. later adaptive optics With the use of telescopes, this problem was overcome by tracking the light movements and more stable images were obtained.
• planetsThey are closer than stars and thus appear larger both with the naked eye and with a telescope.
• In this context, if we consider the ray that comes from the stars as a point, we can say that they vibrate because of the rays that come from the planets, which are a disk rather than a point, because of the many point rays that come from them . we don’t notice. “If it doesn’t vibrate, it’s a planet.“This is where the word comes from.
• But outside the atmosphere everythingis to some extent the victim of this degradation.
• Mostly seen in deserts mirage Events like this are caused by the constant refraction of the light direction by the atmosphere. In this context, a distant object appears as if it is bouncing off the surface of the water.

This was why the distant star and city lights seemed to flicker. You can share your thoughts in the comments section.
