Maps at 7″ resolution of 2.7 mm continuum and J=1→0 C 18 O emission have been made of the DR 21(OH) molecular cloud core. Three compact regions, all of which appear to be actively forming stars, have been detected. Two components, each measuring ∼12,000 AU in size, containing ∼400-500 M ⊙ of material and encompassing H 2 O masers, dominate the most compact, luminous, and massive region. Even though these two components are separated by only ∼8″ on the sky and ∼3.5 km s −1 in velocity, they are quite different, possibly representing different phases of early stellar formation
