Graphic depiction of how the gravity from a cluster of galaxies bends the path of light from a distant supernova. At the top of the graphic is a Hubble image of a field of galaxies on a black background of space. At the bottom of the illustration is an enlarged view of a galaxy from the top image. Both the Hubble image at the top of the illustration and the enlarged inset image at the bottom of the graphic have lines running through them from below the bottom left corner of the respective image extended past the top right corner of each image. The lines extend from a model of the Roman space telescope at the bottom left across each image to a distant galaxy at the top. On each image, the lines represent the light paths from distant supernova in the galaxy at the top right are bent by the cluster’s gravity and redirected onto new paths.
