Rosette nebula is a vast cloud of dust and gas in Monoceros surrounding a cluster of ~6 young, hot stars (NGC2246, Rosette cluster). Their radiation makes the nebula shine by exciting its atoms to emit light. Strong stellar winds from the cluster have created a hollow at the center of Rosette. Star formation is still in progress in this cloud of interstellar matter. The distance of the Rosette Nebula is some 5500 ly, and its diameter about 130 ly.
