Why are the stars twinkling in the sky?

JAKARTA, iNews.id – A blanket of nitrogen, oxygen and other gases keeps the world’s temperature nice and habitable. The gas also protects humans from harmful UV radiation.

However, despite its many good qualities, the atmosphere can be a nuisance to astronomy fans. Why is that? This is because the atmosphere distorts the light at night, thus making the atmosphere of some celestial bodies appear twinkling and glittering.

The technical term for this phenomenon is astronomical sparkle. You may know it by the name twinkling. Like onions, the atmosphere is made up of layers. At the bottom is the troposphere, which begins here at the Earth’s ground level.

Then, about 5 to 9 miles up, that’s where most of Earth’s weather events occur. The other layers are the stratosphere, mesosphere, thermosphere, and exosphere. There is also a region called the ionosphere, which includes the mesosphere and the thermosphere.

These layers have different temperatures. In addition, the density of air varies from one level to another. When the light star entering the atmosphere, he flows into pockets of cold and warm air.
