Eagle Nebula | | | | | |
| | | | | | | automatic translation | | | | | | Eagle Nebula or M6 | | Updated May 20, 2012 | | Category: nebulae |  | | | | | The Space Telescope has photographed very often Eagle Nebula.
The image acquired in 1995 was already showing fine detail within the pillars of gas, real stellar nurseries. From a distance it looks like an eagle.
A closer examination of the Eagle Nebula shows that the bright region is actually a window in the center of a larger dark shell of dust.
Through this window, a very lit workshop appears where a whole open cluster of stars is being formed.
In this cavity tall pillars and round globules of dark dust and cold molecular gas remain where stars continue to form.
Several young bright blue stars are already visible. Their light winds and the remaining filaments and walls of gas and dust.
The emission nebula of the Eagle, labeled M 26, is located about 7000 light years from Earth, covering about 20 light years.
It is visible with binoculars towards the constellation Serpens. | | The thin vertical column of dust forming stars that we see in the center of the image a little to the left, is known as the Fairy of Eagle Nebula. * Eagle Nebula or M16.
The image to three colors and was taken by the 0.9 m telescope at Kitt Peak, Arizona, United States. | |

This is actually a mirage inflated tower of cold gas and dust separating from a stellar nursery called the Eagle Nebula.
The slender tower measures 9.5 light years, ie about 90 000 billion km, about twice the distance from our Sun to the nearest star, Proxima Centauri.
The stars of the Eagle Nebula are born in clouds of cold hydrogen gas.
These regions are carved by the chaotic energy of young stars that reveal beautiful landscapes.
The tower is a cloud giant incubator for those newborn stars.
On the top of the image, we see a torrent of ultraviolet light emitted by hot young stars eroding the pillar of dust. Starlight illuminates the entire gas bubbling from the tower.
This character ghostly gas stands in the mist, like a three-dimensional structure.
The dark cloud of hydrogen and dense at the top of the tower resists erosion greedy stars, their flames that sweep the surrounding dust.
Some celestial clouds so thick they resist longer to ultraviolet light explosions of hot young stars.
Inside the gaseous tower, there are certainly star formation.
These stars form after attracted to them, dense dust, which under the influence of gravity came to light.
Other stars are formed by the pressure of the gas clouds that have been heated by nearby stars, which in time collapse under their own weight, to switch to other stars.
The cluster of young stars shining in parts of the tower, as the great shining heap wing-shaped top of the structure, so the gas heater at the top of the tower, they create a shock front, pushing the nebula as seen in the top left of the image.
The heated gas expands, it acts as a battering ram, pushing the dark cold gas.
The intense pressure compresses the gas, which makes easier the formation of other stars.
This scenario may continue as the shock front moves slowly along the tour.
The colors of the image were produced by gas energized by the powerful ultraviolet light from the star cluster.
The blue color at the top of the tower, is emitted by oxygen. | | The base of the tower of red in the lower region is composed of incandescent hydrogen.
The image of Eagle Nebula was taken in November 2004 by the Advanced Camera for Surveys aboard the Hubble Space Telescope, Space Credit NASA / ESA .
* A tower blown cold hydrogen and dust rises midst of a stellar nursery called the Eagle Nebula.
This character ghostly gas, stands in the mist, like a three-dimensional structure.
The stars continue to be born when winds are light from the star clusters, repel dust, thus separating their gas supply.

| | | | | | | | The Pillars of Creation | | | | |  | | | | | This image has become one of the most famous images in modern times.
It was taken by the Hubble Space Telescope in 1995.
It shows huge clouds of hydrogen gas and dust mass of 10 to 50 times the mass of the Sun, called the Pillars of Creation.
These giant pillars extend for light years away and are so dense that the gravitational force inside, creates stars.
At the top of each pillar, the intense radiation of bright stars, lights up the surrounding matter.
In light of these dense stellar nurseries, highlights the magnificent monsters of dust from the Eagle Nebula. Recent observations of the Spitzer telescope, indicates that these superstructures of dust, are ephemeral and will eventually be blown away by the shock wave of a supernova.
In the heart of the Eagle Nebula, we find large columns of dust.
These columns contain, Bok globules (huge clouds of gas and dust mass of 10 to 50 times the mass of the Sun) where stars are born.
These columns are dubbed the Pillars of Creation.
