Here's why:
* Earth's Atmosphere: The air around us is constantly moving, creating pockets of different temperatures and densities.
* Light Bending: As starlight travels through these pockets, it gets bent and refracted (like light passing through a prism).
* Color Shift: The bending of light causes different colors to be refracted at slightly different angles. This makes the star appear to change color quickly, creating a flickering effect.
Important Note: While the color change is real, it's not a property of the star itself. The star's true color depends on its temperature and composition.
