This sneak peek gives as- tronomers a major jumpstart on a core Roman survey, helping scien- tists learn more than they couldfrom either telescope alone. “This is the only time Euclid has paused its normal sky survey, which is mainly geared toward cosmol- ogy,” said Jason Rhodes, a senior researchscientistatNASA’sJet Propulsion Laboratory in Southern California. Rhodes serves as boththe U.S. Euclid science lead and the NASA JPL Roman project scientist. “This takes a lot of work and plan- ning, so it really has to be some- thingwithahighimpactforscience. Adding Euclid’s snapshot to Ro- man’s future survey will help usmap our galaxy better and identify hard- to-find cosmic treasures like isolated black holes and rogue planets more easily.” Euclidtookonedayoutfromitssix- year prime mission to preview the areaofskythatwillbetargetedby Roman’s Galactic Bulge Time-Do- mainSurvey,whichwillprovideone of the deepest views ever into the center of our galaxy.
