【#Tech24H】The corona is the outermost layer of the solar atmosphere, sitting above the chromosphere. With temperatures reaching millions of degrees Celsius, it nevertheless contains enormous plasma structures at only about 10,000 degrees Celsius, extending thousands of kilometers. These structures are highly dynamic and sometimes appear as erupting, fountain-like jets, scientists call them solar prominences. For the first time, German scientists have incorporated deep solar activity into prominence models through computer simulations, revealing their formation mechanism. The Sun’s magnetic field does not arise from nothing; it originates from turbulent plasma flows deep within the Sun. This hot plasma churns beneath the visible surface, generating a complex and ever-changing magnetic field that extends into the corona. The formation and maintenance of prominences are precisely the result of the interaction between magnetic fields and plasma. [ By Zhang Liyan | Tang Ruohan ]
