Astronomers may have spotted a nanoflare on Sun.

Islamabad -- Researchers may have found the long-sought 'nanoflares' thought to heat the solar corona to its incredible temperatures.A new study published in Nature Astronomy marks the first-time researchers have captured the full lifecycle of a putative nanoflare - from bright origins to blistering demise.Nanoflares are tiny eruptions on the Sun, one-billionth the size of normal solar flares. Eugene Parker - of Parker Solar Probe fame - first predicted them in 1972 to solve a major puzzle: the coronal heating problem.That's the mystery of how the Sun's outer atmosphere, or corona, gets so incredibly hot. Despite being much farther away from...
