| Description: Gravitational fields cause light to change direction. As a star with a planet passes between Earth and a more distant star (b), the light from the distant star is focused toward us, making the distant star appear brighter. The focusing of the distant star’s light occurs twice, once by the closer star and once by its planet (c), making the distant star change brightness. For these simulations, the closer star and planet are 17,000 ly away, while the distant star is 24,000 ly away Picture Stats: Views: 572 Filesize: 137.63kB Height: 900 Width: 660 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=15955 |
