Scientists Discovered that Huge Wave Energy in Highly Magnetized Sun’s Plasma Maintains Million-Degree Corona
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 the photosphere) of the Sun the temperature drops to about 5,000 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-intuitive example. This is called the coronal heating problem which consists a century-long challenge to physicists.
