NASA successfully deciphered the long-standing mystery about the Sun.
The sun is about 5,500 degrees above its surface and its corona (halo) is 200 to 500 times hotter, a terrible number.Nanoflares heat up the Sun's atmosphere
Sun physicists at NASA have confirmed that small and sudden bursts of heat and energy, called nanoflare, make the temperature of thin and translucent gases in the Sun's atmosphere
