M16 - Eagle Nebula in Narrow Band
|
The Eagle Nebula (also known as
Messier Object 16, M16 or NGC 6611), perhaps one
of the most famous and easily recognized space
objects, is a young open cluster of stars in the
constellation Serpens, discovered by Jean-Philippe
de Cheseaux in 1745-46. It is associated with a
diffuse emission nebula, or H II region, which is
catalogued as IC 4703. This region of active
current star formation is about 7,000 light-years
distant. The brightest star in the nebula has an
apparent magnitude of 8.24, easily visible with
good binoculars.
Images made in 1995 by the
Hubble Space Telescope greatly improved our
understanding of processes inside the nebula. The
region of the Eagle Nebula known as the "Pillars
of Creation" is a large region of star formation.
Its small dark areas are believed to be
protostars. The pillar structure of the region
resembles that of another, much larger star
formation region, imaged by Spitzer Space
Telescope in 2005 in Cassiopeia, which is
designated W5 and usually called "Mountains of
Creation".
