Mystery of sun's corona solved? It's nanoflares, scientists say

One of the greatest mysteries of how stars behave has been right in our own backyard: the sun’s corona. Scientists have long wondered what heats this thin, ethereal shell of particles to roughly 300 times the temperature of the surface of the sun itself. Now, after combining evidence from a sounding rocket and a black-hole-hunting telescope and computer modeling, researchers say they’ve found the cause: nanoflares. “We have for the first time direct proof that nanoflares exist and heat the corona,” said Jim Klimchuk, a solar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “This proof takes the form of superhot plasma …...
