(Anirudh Sharma) Twinkling stars have stopped forming in the sky. This is strange to hear, but true. About a thousand crore years ago, the process of star formation slowed down. But the stars have stopped forming after the hydrogen gas molecules available in the constellations are gone.
Indian scientists have inspected 8500 constellations from the world’s largest telescope and uncovered the mystery of the reasons for not becoming stars. This research of Indian scientists has been published in the science journal ‘Nature’. The biggest feature of this research is that it has been prepared by the team of Indian astronomers.
It has fully mobilized Indian resources, especially using the Giant Meterwave Radio Telescope (GMRT). The team comprises the National Center for Radio Astrophysics at the Pune-based Tata Institute of Fundamental Research and Aditya Chaudhary from the Raman Research Institute in Bangalore, Nisim Kanaker, Jayaram Chengalur, Shiv Sethi and KS Dwarkanath.
Stars were very fast for 100-200 million years: Chaudhary
Aditya Chaudhary, author of the research, says – ‘In the early constellations, stars were rapidly formed from gaseous molecules for 100 to 200 million years. After that when the availability of hydrogen gas was exhausted, the process of star formation also slowed down and eventually stopped.
Estimation of the weight of hydrogen molecules in remote constellations was possible due to the upgraded version of GMRT. Pro. Nissim Kanekar said- ‘This is the first research in the world to give an explanation with direct evidence of the end of the wiring process.’
