Why Do Stars Twinkle?

The video explains why stars twinkle, a phenomenon known as stellar scintillation, caused by Earth's atmosphere. As starlight passes through atmospheric layers, it refracts, making stars appear to flicker. The Hubble Space Telescope avoids this issue by capturing images from space, resulting in clear photos. Twinkling also helps distinguish stars from planets, as planets appear more stable due to their proximity. The video concludes with a fun fact about wishing on stars.
