Hence, it is rare that an open cluster survives long enough for one of its members to form a planetary nebula.

Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars that energizes the glowing gas.

The center of the Rosette Nebula, which glows with the red light of ionized hyrdorgen, is fueled by a central cluster of powerful giant stars.
