| Description: Gravitational Lensing of Quasars Image from the Hubble Space Telescope that shows the gravitational lensing of a quasar in the constellation of Pegasus. The quasar, about 8 billion ly from Earth, is seen as four separate images that surround a galaxy that is only 400 million ly away. This pattern is called an Einstein cross. The diffuse image at the center of the Einstein cross is the core of the intervening galaxy. The physical effect that creates these multiple images is the same as that seen for galaxies Picture Stats: Views: 611 Filesize: 330.58kB Height: 900 Width: 918 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=18771 |
