But Planets Dont [L7SbVil6iFG] Health Updated on August 05, 2026 EDT — Published on August 05, 2026 EDT Have you ever noticed that stars seem to twinkle while planets shine with a steady light? The answer has nothing to do with the stars themselves. It's actually caused by Earth's atmosphere. As starlight travels through layers of turbulent air, it constantly bends and changes direction, making distant stars appear to flicker. Planets, however, appear as tiny disks rather than single points of light, so these atmospheric distortions average out and they usually shine steadily. This fascinating effect is called atmospheric scintillation and is one of the reasons astronomers build observatories on high mountains and even place telescopes like the Hubble Space Telescope above Earth's atmosphere for clearer views of the universe.
