NASA’s Hubble Space Telescope has captured an image featuring a barred spiral galaxy and a gravitational lens, as part of preparations for the new Nancy Grace Roman Space Telescope.
The Oct. 22, 2026, image shows a sweeping barred galaxy at center and a gravitational lens at bottom right. The observation is one of many gravitational lensing images taken by Hubble in preparation for Roman. Astronomers will analyze the gravitational distortions to learn more about dark matter in foreground galaxies and lay 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.
The Nancy Grace Roman Space Telescope is NASA’s next major observatory, designed to study dark energy, exoplanets, and infrared astrophysics. This preparatory survey uses Hubble’s sharp vision to identify targets for Roman’s wider field of view.
Analysis
Why This Matters
- Gravitational lensing is a key tool for studying dark matter, which makes up most of the universe’s mass.
- Hubble’s preparatory work will enable Roman to hit the ground running, maximizing its scientific return.
- The collaboration between Hubble and Roman demonstrates the value of successive space observatories.
Background
The Hubble Space Telescope has been in operation since 1990, providing groundbreaking observations. The Nancy Grace Roman Space Telescope, formerly known as WFIRST, is scheduled to launch in the mid-2020s and will have a field of view 100 times larger than Hubble’s infrared camera. This preparatory survey uses Hubble’s ability to resolve fine details to identify gravitational lenses that Roman can then study with its wider survey capabilities.
What to Watch
- The Roman Space Telescope’s launch date and initial observations.
- Future Hubble images from this preparatory survey.
- Results from analyses of the gravitational lensing data for dark matter studies.
