There is a dark nebula in the tail of the constellation Serpens, located in the middle of the Milky Way in the southern sky during the summer. This nebula, called the Eagle Nebula (M16, NGC 6611) because it resembles an eagle soaring into the sky, is located about 6,500 light-years away from Earth.
This photo was taken of part of the Eagle Nebula, the site of the birth of stars. New stars are being formed in the towering black pillar of interstellar gas and interstellar dust, and at the top of the pillar, recently born stars are pouring out intense starlight, revealing the dense gas clumps containing stars in the pillar one by one.
So these pillars are called the Pillars of Creation. The pillars of creation are huge. The largest left pillar is a whopping 4 light years (about 40 trillion km) long.
