About 200 light -years from black hole Center Milky Way Lies a region that is not as fertile as scientists would think.
This star -forming cloud of gas and dust, Sagittarius 100is filled with all the material to make star babies, but still his new stars’ extraction remains relatively low, despite the fact that he has probably already given birth to thousands of stars. Scientists have indicated Space Telescope James Webcooperation of NASA and its European and Canadian space Colleagues in this mysterious star nursery to try to understand why. With its powerful infrared vision, the telescope managed to give a clearer picture.
Thehe findingspublished in The astrophysical magazine In two documents, provide New insight Why some star clouds may look relatively impotent. Researchers now believe that strong magnetic fields may be responsible for lack of production.
“A big question is if there is so much thick gas and dust here. We know that the stars are formed in these types of clouds, why are so few stars born in Sagittarius with?” said John Bali, Astrophysicist of the University of Colorado Boulder, in a statementS “For the first time, we see that strong magnetic fields can play a major role in stopping the star formation.”

Placing the star-forming region in a context

Web was built to detect invisible light in infrared wavelengths. Space dust and gas darken the view of extremely distant and inherent sources of weak lights, but infrared waves can break through the clouds. A web -like scientist has the power of the telescope that it can feel the warmth of a bee on the moon.
Scientists say that understanding what is happening in Sagittarius is an important step in understanding the formation of stars in general. Stars create most chemical elements on Earth, including carbon and oxygenwhich are the main ingredients for life. But even experts admit they have a lot to learn how Universe Makes new stars.
The researchers have confirmed that two huge stars, every 20 times larger than the mass of the sun, grow inside Sagittarius C, exploding powerful jets of gas as they develop. They also identified five smaller stars blurred in thick layers of dust.

Web also found 88 strange structures made of glowing hydrogen, considered to be Shock waves caused by young stars who throw away their own material into space. In addition, scientists have discovered a completely separate stars factory nearby with at least two of their own growing stars.
Prior to these studies, Sagittarius showed dozens of filaments similar to threads, several light years long, in hot hydrogen gas surrounding the main star cloud. Scientists consider magnetic powers of The over -fat black hole on the Milky Way., Sagittarius A*It may be strong enough to push against gravity attraction. Perhaps such tension could prevent the dense clouds from collapsing and forming more stars.
Samuel Crowe, a Rhodes scientist at the University of Virginia, who led the study, said Sagittarius with it turned out to be an important laboratory for testing theories to form stars.
“This discovery opens new questions about how magnetic fields affect the birth of the stars,” he said in a statement, “both in our galaxy and beyond.”
