How come some stars look like they are flashing?
The variations in the light intensity are due to disturbances in the
atmosphere between your eye and the star. If these disturbances are
as big as the star, the star will appear to twinkle. The size of the
moon and planets is larger than these disturbances and they do not
twinkle. If the size of the fluctuations were smaller in the
atmosphere were smaller the stars would not appear to twinkle. If
we were to get above the atmosphere , there should be no twinkling.
