Strong new evidence supports a theory that the Sun’s corona is heated by tiny explosions called nanoflares. The Sun’s visible surface, called the photosphere, is some 6,000 Kelvins, while the corona regularly reaches temperatures which are 300 times as hot. For more than five decades, scientists have tried to figure out what causes the corona [...] —> Read More
