Question

Quizplus · Accepted Answer

Modern astronomers believe that the corona is heated by magnetic carpets, which are complex systems of magnetic fields that continually twist and interact, causing energy to be released as heat. This is currently the most widely accepted theory for the extreme temperature of the corona, which can reach millions of degrees Celsius despite being farther away from the Sun than the relatively cooler photosphere.
