SIRIUS flickers - Brightest Star in the night sky ▶ Telescope view. Subtitles translation
Brightest star in the night sky - Sirius flickers ▶ Telescope view. Sirius is the star of the winter sky, but in spring it is also visible - at sunset. But it is not the star itself that flickers. Atmospheric turbulence leads to the refraction of light rays of the star, which causes luminance and color flicker.
If the Earth did not have an air shell of the atmosphere, then we would not see such a twinkling of stars.
