NASA’s Hubble Marks Way for Roman Space Telescope

A sinuous spiral galaxy (center) appears in the same field of view as a vivid gravitational lens (right corner) in this Hubble image.NASA, ESA, and X.

This observation is one of many gravitational lensing images taken by NASA’s Hubble Space Telescope in preparation for science with the new Nancy Grace Roman Space Telescope. Astronomers will use these images to analyze gravitational distortions to learn more about dark matter in the foreground galaxies and to lay the groundwork for future Roman observations. Images like this offer a glimpse of how Hubble and Roman will work together to build an even more comprehensive picture of the cosmos. Image credit: NASA, ESA, and X.
