Both galactic nebulas and globular clusters occur in our galaxy. Distinguish between them.
Galactic nebulae are large clouds of gas and dust within our galaxy. They give off light by absorbing and re-emitting light from a few young and very hot stars within the nebula.
Globular clusters are groups large numbers of old stars that remain together in a spherical cluster, held together by mutual gravitational attraction. They contains very little gas or dust.
