A NASA team led by a scientist of Indian origin has revealed the reason behind the high temperature of the sun’s mooring region

A NASA team led by a scientist of Indian origin has revealed the reason behind the high temperature of the sun’s mooring region
NEW DELHI: Mystery has always surrounded how the sun-baked area relates to its underbelly Layers of the atmosphere It undergoes an impressive heating process that ranges from 10,000 degrees Fahrenheit to nearly 1 million degrees Fahrenheit, which is 100 times hotter than the adjacent shiny surface. Recent research, led by scientist Sovik Bose, has shed light on High temperature Mechanism of action inside the moss.
The research used data collected from NASAThe High-Resolution Imaging Coronal (Hi-C) sounding rocket and the Interface Region Imaging Spectrograph (IRIS) mission, combined with complex 3D simulations, to reveal the potential role of electrical currents in the heating process.
Within this region is a complex network of magnetic field lines, resembling invisible strands of spaghetti. This magnetic entanglement generates electrical currents, which heat materials over a wide temperature range, from 10,000 to 1 million degrees Fahrenheit. This localized heating in the moss appears to complement the heat emanating from the several million-degree scorching corona above. These results, detailed in Nature Astronomy on April 15, provide important insights into understanding why the Sun’s corona exceeds the surface temperature.
“Thanks to our high-resolution observations and advanced numerical simulations, we are able to unravel part of this puzzle that has puzzled us for the past quarter century,” said author Sovik Bose, a research scientist at Lockheed Martin Solar and Lockheed Martin Solar. Astrophysics Laboratory, Bay Area Environmental Institute, and NASA Ames Research Center in Silicon Valley, California. “However, this is just part of the puzzle, it does not solve the entire problem.”
More opportunities to unravel the full mystery are on the horizon: Hi-C is scheduled to launch again this month to capture a solar flare, likely including another algae region besides IRIS. However, to obtain observations comprehensive enough to show how the corona and the algae are heating up, scientists and engineers are actively developing new instruments for the future Multi-Eaperture Solar Energy Explorer (MUSE) mission.
The tiny, bright, patchy structure made up of plasma in the solar atmosphere bears a striking resemblance to terrestrial plants, leading scientists to call it “algae.” This moss was first discovered in 1999 by NASA’s TRACE mission. They form mostly around the center of sunspot clusters, where magnetic conditions are strong.
