NASA's Hubble charts path for Roman with gravitational lenses
A sweeping barred spiral galaxy marks the spot in this image, but the real treasure is the gravitational lens in the lower-right corner, where a distant background galaxy is being magnified and distorted by the gravity of a closer galaxy.
AI Summary

The lens magnifies and distorts a distant background galaxy using the gravity of a closer galaxy. This observation is one of many Hubble lensing images taken to prepare for research with the upcoming Nancy Grace Roman Space Telescope.
