Embedded stellar clusters, or simply embedded clusters (EC), are open clusters that are still surrounded by their progenitor molecular cloud.They are often areas of active star formation, giving rise to stellar objects that have similar ages and compositions.Because of the dense material that surrounds the stars, they appear obscured in visible light but can be observed using other sections of the electromagnetic spectrum, such as the near-infrared and X-rays that can see through the cloud material. In our Galaxy, embedded clusters can mostly be found within the Galactic disk or near the Galactic center where most of the star-formation activity is happening.
