Description

The Eagle Nebula is part of a diffuse emission nebula, or H II region. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula is approximately 9.5 light-years or about 90 trillion kilometers long.

The cluster associated with the nebula has approximately 8100 stars, which are mostly concentrated in a gap in the molecular cloud. The brightest star (HD 168076) has an apparent magnitude of +8.24. This star has a mass of roughly 80 solar masses, and a luminosity up to 1 million times that of the Sun. The cluster's age has been estimated to be 1–2 million years.

Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars.
