Roman’s Galactic Plane Survey
Early in the mission Roman will image several hundred square degrees along the plane of our galaxy, peering through dust that hides much of the Milky Way at visible wavelengths.
Planned at roughly 700 square degrees over about a month of observing, the survey targets star-forming regions, star clusters and the structure of the galactic disk, and covers a much larger area of the bulge than the time-domain survey.
It was defined through the same open, community-led process as the core surveys and is scheduled for the first part of the mission.
