Color image in infrared light, showing a cluster of newborn stars (orange). Hot gas spots are white, and young stars streams are blue.
Scientists have found new evidence of stellar education in our galaxy. With the help of an infrared telescope it was possible to fix how stars resembling the sun grow inside a cluster.
Giant gas clouds have been found moving outward from areas in which stellar birth occurs. Star nurseries are capable of producing tens and hundreds of stars with different masses and sizes.
Objects appear when gravity compresses cold rotating dust and gas clouds, forming discs. When it slows down, a star begins to be born. This leads to powerful gas outflows (jets). Planets can also form in such disks, so the presence of a jet is an indicator of the emerging planetary system. Stars whose massiveness exceeds the sun by 8 times, emit ultraviolet rays into space, destroying natal clouds.
For the study, scientists used the NICFPS instrument (near-infrared camera and spectrometer) on the 3.5-meter New Mexico telescope. He managed to penetrate into 26 dusty clouds with star clusters. The combination of IR filters made it possible to distinguish the streams of newborn stars from other types of light. It was possible to identify 36 jets in 22 sites. This proves that even such crumbs create powerful jets. When the radiation destroys the surrounding cocoon, this reactor will shut down.
