M 16 - Eagle Nebula

The Eagle Nebula (M16) is an active star-forming region dominated by the open cluster NGC 6611. NGC 6611 contains many bright stars of spectral types O and B. M16 and NGC 6611 can be seen through a "window" in the dense molecular cloud that covers the entire area.
Strong stellar winds from the bright O-type stars in the cluster collide with the edges of the molecular cloud, breaking them into pieces and causing the material to glow. This process forms structures like the famous "Pillars of Creation" and induces secondary star formation.
M16 is about 6,500 light-years away.
