A new look at the Milky Way galaxy’s heart by ESA’s Euclid mission, which includes contributions from NASA, coincides with a region that NASA’s Nancy Grace Roman Space Telescope will observe upon its launch later this summer. This preview provides astronomers with a significant advantage for a core Roman survey, enhancing their understanding beyond what each telescope could achieve individually.

A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA’s Nancy Grace Roman Space Telescope, launching later this summer. This sneak peek gives astronomers a major jumpstart on a core Roman survey, helping scientists learn more than they could from either telescope alone.
