telescope “Hubble” watching the birth of stars
This amazing image was recently observed by astronomers working with the space telescope “Hubble” space agencies NASA and ESA. The photo shows the Chameleon cloud region, where currently there is a formation of a new young blue stars. This process created a structure, called HH 909A and occupies a large part of the image.
Incredible bright area surrounding the emerging star, is formed by extremely rapid release of gas produced from this field stars. Hot streams of gas collide with colder gas located in the structure of HH 909A, as a result of forming the glow of varying intensity and brightness. Needless designation HH usually describes Herbig-Haro objects, small areas of nebulae formed around young stars.
While inside the star will not start its own nuclear fusion, the protostar will continue to be fed by matter from the surrounding gas cloud. This will continue until the star attains its critical mass, and the processes accompanying this event, do not ignite a massive cloud of molecular gas is not Kindle, turned into one big giant flaming ball.
HH 909A is located very close to the Earth at a distance of only about 500 light-years away in the constellation Chameleon. As in other stellar nurseries (places in space where there is intensive nucleation stars), including Orion Nebula, in the molecular cloud Chameleon-1 there are a large number of Herbig-Haro objects.
