NGC6820 Cluster and Nebula
NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula.
The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars.
Remarkable dark globules of gas and dust are also visible in the nebula,
