Question

why do stars twinkle please tell me in simple language and in detail

Answer 1

Stars twinkle because their light must pass through pockets of Earth's atmosphere that vary in temperature and density, and it's all very turbulent. On rough nights, a star appears to shift position constantly as its light is refracted this way and that

Answer 2

stars twinkle due to atmospheric refraction,i.e. because of the difference in the temperature of the air layers of the atmosphere.
