Varanasi, Uttar Pradesh India:
These novel scientific results, accompanied by the first ever high resolution view of sunspot umbra, and high energy wave dynamics in its plasma fibrils are published in the prestigious Nature Astronomy Journal on 25th May 2023.
The globally acclaimed solar and heliospheric physicist in Indian Institute of Technology (Banaras Hindu University), Dr. Abhishek Kumar Srivastava is the part of this investigation, who played a significant role in framing the scientific works. He said that this new scientific discovery will change the view of strongly magnetized plasma regions at the Sun as it was never seen before, and will play a significant role in solving the most outstanding coronal heating problem. It will also be an outstanding scientific result for the next generation solar telescopes, and a ready reference to the laboratory plasma experiments where scientists are trying to confine the plasma and generate the green energy for the benefits of mankind.
He further informed that the sun is powered by nuclear fusion of hydrogen at the core, where the temperature reaches 16,000,000 degrees Celsius. At the visible surface (or photosphere) of the sun the temperature drops to about 5,800 degrees Celsius. It is intuitive that the hydrogen gas located further away from its core should be cooler. The corona is more distant from the core than the photosphere, but its temperature reaches millions of degrees. No current theory could explain this counter-example, this is called the coronal heating problem, a century-long challenge to physicists.
