Life and Death of a Star documentary. Firstly, where are stars born? Found in a region of the cosmos clumps of gas and dust as dark and dense than projected shadows strongest recorded to date in interstellar space for this class of cosmic objects. Infrared observations of these unique regions, made by the Spitzer Space Telescope of the NASA, reveal details of the process of star formation that occurs after the “backdrop” of dust, and these include key clues to know much better how they form the brightest stars.
These clumps observed by the team of Michael Butler of the University of Zurich in Switzerland, are the darkest parts of a vast cosmic cloud of gas and dust located about 16,000 light-years away from Earth. The authors of the new study were served by these lumps projected to measure the structure and mass of the cloud shadows.
The results suggest that this cloud is likely to evolve into one of the most massive young star clusters in our galaxy. From the denser clumps will be born the stars big and bright of the cluster, the type or, whose training has intrigued scientists for a long time. These giant and very bright stars, although very short life, exert a great influence on their environment, and are also major producers of heavy elements necessary for the formation of rocky planets like Earth and the emergence of life on them.
Detailed map made by new observations helped determine the mass of the cloud is equivalent to 70,000 sun-like stars concentrated in a region about 50 light-years in diameter.
It is believed that most stars in the universe, including perhaps our Sun were formed in large groups in this class environment. Star clusters with discrete masses are quite common and well studied. But clusters that give rise to massive stars with masses as being formed cumulus cloud studied, are rare and far between, which makes it more difficult to investigate, and makes studies like new in great opportunities for unravel mysteries of the genesis of the most massive stars.
