2019-08-26/29 / Click on image to enlarge

The Eagle Nebula - already part of Messier's famous catalogue in 1764 as M16 - is a 5.5 million-year-old cloud of molecular hydrogen gas and dust stretching approximately 70 light-years by 55 light-years. One suspects the Eagle Nebula has several star-forming regions within it.

This enormous stellar nursery lies 7,000 light-years away in the inner spiral arm of the Milky Way, known as the Sagittarius-Carina Arm. In Earth's sky, the Eagle Nebula is found within the constellation of Serpens.


"One of the best-known pictures of the Eagle Nebula is the Hubble Space Telescope image taken in 1995, called the Pillars of Creation."
