Summary
| Description |
English: Comparison of twinkling of a star (top) and a planet (bottom) by CMG Lee. The turbulent atmosphere (shaded blue) distorts their wavefronts (cyan lines) differently with time, like caustics on a swimming pool floor. When a dark part hits the observer (white circle), the object appears dark, and vice versa. An object with larger angular size smears the pattern, yielding less change in intensity. The caustic network image is from http://commons.wikimedia.org/wiki/File:Caustic_light_-_Flickr_-_fdecomite.jpg . |
