The Eagle Nebula  M16, and as NGC 6611, its name derives from its shape that is thought to resemble an eagle. It contains several active star-forming gas and dust regions, including the famous "Pillars of Creation", photographed by the Hubble Space Telescope.
The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. The tower of gas (Pillars of Creation) that can be seen coming off the nebula is approximately 9.5 light-years or about 90 trillion kilometers long.
