Description
M16, the Eagle Nebula, lies 7000 light-years from Earth, which places it in the Sagittarius arm of the Milky Way galaxy. It is a nebula with notable star forming regions, including the "Pillars of Creation" seen at the center and made famous by the Hubble Space Telescope image. The longest pillar is about 6 light-years long. Another star forming region is "The Spire", which looks like its poised on a pedestal and is oriented horizontally to the upper left of the Pillars of Creation. The Spire is 9 light-years long.
