Roman joins an international cohort of teamworking telescopes.

Roman will work in tandem with many other NASA-led and international missions to provide the most complete view of our universe yet. Roman’s large panoramas will uncover interesting targets that Hubble could follow up on using infrared, visible, and ultraviolet light to offer a more comprehensive view. NASA’s James Webb Space Telescope can then use its larger mirror and more powerful vision to deliver even more detailed, ultra-sharp observations. And Roman can view regions around objects Hubble or Webb observe to offer context.
 
Euclid, an ESA (European Space Agency) mission with key contributions from NASA, will observe a larger area of the sky than Roman, though with less detail. Since their survey areas will overlap, scientists can use Roman’s higher-quality data to apply corrections to Euclid’s, then extend these refinements over Euclid’s much larger area.
 
Scientists can also pair Roman’s infrared data with visible-light observations from the ground-based Vera C. Rubin Observatory, a National Science Foundation–Department of Energy collaboration. That will allow astronomers to inch closer to achieving Roman-like quality over Rubin’s much greater sky coverage.
 
By showcasing technology to directly photograph Jupiter-like exoplanets, Roman will also provide a crucial stepping stone for NASA’s Habitable Worlds Observatory concept, a flagship space telescope that would be designed to photograph Earth-like planets in other solar systems for the first time ever.
