![This animated GIF shows how light is bent by massive objects that create dents in space-time. The first scene shows a white grid on a black background, which represents space-time. In the center is a star shown as a glowing yellow ball. The star creates a dent in the space-time grid, so the lines of the grid are curved under and around it. A line of yellow light comes down from the top of the image and arcs around the star. Then the scene changes to show the Hubble Space Telescope, a silver cylindrical object, in the bottom right of the image, pointed up toward the left. In the upper left is a fuzzy white blob with yellow lines moving toward Hubble. Between them, in the center, is a cluster of galaxies, depicted as several different-sized orange and white specs of light. As the yellow lines approach the galaxy cluster, they bend around it, ending up pointing toward the telescope.](https://science.nasa.gov/wp-content/uploads/2023/09/Light_Bending.gif?w=4096&format=png)
