Discovery of long sought tiny explosions on the Sun

The mechanism responsible for heating the corona to two million degrees, especially for the quiet Sun, has remained an enduring mystery. Scientists at the National Centre for Radio Astrophysics, Pune have now found the first direct observational evidence in support of one of the proposed mechanisms for heating the quiet corona. They have discovered tiny flashes of radio light from all over the Sun, smoking guns for tiny magnetic explosions, which convert the copious magnetic energy present in the quiet corona into heat.
