Gravitational Lens |
||||||
 |
||||||
|
||||||
| A gravitational lens occurs when the gravitational pull of a very massive object, such as a galaxy, bends the light of an object behind it. In this photo, the bright yellowish object in the center of the image is a massive galaxy. Another galaxy is hidden behind it. The nearer, visible galaxy bends the light of the hidden galaxy and makes its light appear as blue streaks around the central galaxy. | ||||||
