Stellar winds have considerable energy.
Dust nebulae is repelled by the powerful light energy of stars, known as the "stellar winds". Gravity brings the matter into huge clouds of dust. At the heart of the clouds the matter is concentrated, pressure and temperature become unimaginable, they eventually 'paste' nucleons them the matter merges and nuclear reactions keep coming. It is in these nebulae dark matter than Hubble telescope can witness the birth of stars. Dust nebulae is then repelled by the strong winds of the stars. Looking closely at the dust of the reflection nebula IC 349 in the Pleiades star cluster (M45), Hubble gives us a glimpse, all the power of 'wind' of starlight (see image cons ). Hubble has captured the misty tendrils of this dark interstellar cloud blown by the passage of one of the brightest stars of the Pleiades.
Invisible in this image, the star Merope (outside the top left) like a torch shining on the wall of a cave, reflects light on the dark clouds of cold gas interlaced with dust.
These nebulae are called reflection nebulae. Rays of colored light in the upper left from the star, are not real, this is an optical phenomenon produced by the telescope's mirror. In contrast, the remarkably parallel wisps extending from lower right to upper left are the actual characteristics revealed for the first time thanks to the high resolution imaging of Hubble. Astronomers George Herbig and Theodore Simon of the University of Hawaii have made these observations on 19 September 1999. Twenty years after its launch Hubble continues to give us these masterpieces of creation.
This wonderful telescope allows us to glimpse the immensity of the universe from which we came.
This image shows a beautiful creature sculpted by stellar winds. This is actually a mirage tower blown cold gas and dust remover a stellar nursery called the Eagle Nebula. The slender tower measures 9.5 light-years, i.e. about 90,000 billion kilometers, 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. This is the light energy of these young stars sculpts beautiful scenery. This giant infernal tower of dust is a incubator cloud for those newborn stars.
On top of the image, we see a torrent of ultraviolet light from hot young stars eroding the pillar of dust.
Starlight emerging ended by illuminate the entire gas tower and a ghostly figure stands in the "mist" cosmic. The dark at the top of the image, representing the personage's shoulders, is a hydrogen cloud dense enough to withstand the pressure of stellar winds, but they will ultimately sweep of their flames, surrounding dust. Throughout the tower you can see the heavenly clouds so thick they may resist ultraviolet light winds from hot young stars.
Inside the gaseous tower, there are certainly young star formation hidden behind the thick layer of dust.
The stars light up after attracted to them, sufficiently dense dust, gravity ended by trigger nuclear reactions. But other stars are formed due to the pressure of the gas clouds that have been heated by nearby stars, which slowly collapse under their own weight, up to to be born other stars.
The brilliant young star clusters in certain regions of the tower, as the great mass brilliant wing-shaped top left of the structure, heat so the gases at the top of the tower, they create a shock front, pushing share nebulae and others. The heated gas expands and acts as a battering ram, pushing the cold gas and dark.
These scenarios will continue for a long time, until the dust is sufficiently dense to generate stars.
Hubble shows us here the depth and vastness of space.
It is thanks to images like this one someday we will decipher the key that connects us to the observable universe. The dominant colors of the image were produced by gas excited by the powerful ultraviolet light from the star cluster. The blue color at the top of the tower is emitted by oxygen while at the foot of the tower, in the lower region of red color, it is hydrogen that illuminates the pedestal of the personage.
The image of the Eagle Nebula was taken in November 2004 by the Advanced Camera for Surveys aboard the Hubble Space Telescope, Space credit NASA / ESA.
