Description

The Rosetta Nebula, Caldwell 49

This emission nebula is approximately 5000 ly from Earth and approximately 130 ly in diameter.

It is closely associated with the open cluster in its center, NGC 2244.

The bright hot stars in the cluster excite the surrounding nebula cloud causing it to glow.
