| Description: The star Fomalhaut, blocked out so that its light does not obscure the disk, is surrounded by gas and dust in a ring whose center is separated from the star by 15 AU, nearly as far as Uranus is from the Sun. This offset is believed to be due to the gravitational effects of a giant planet orbiting Fomalhaut. This system is 25 ly from Earth. The dimmer debris in that system and between us and it scatters light that is considered “noise” in such images Picture Stats: Views: 722 Filesize: 477.96kB Height: 900 Width: 1125 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=15951 |
