"An international group of researchers have found that stars similar to the Sun produce a gigantic outburst of electromagnetic radiation, or superflare, about once every 100 years per star.
The researchers, including some from Japan and Europe, released their findings in the US journal Science on Friday.
They studied more than 56,000 stars with fundamental parameters similar to the Sun. They used the Kepler space telescope to observe brightness fluctuations over a period of time.
The group identified more than 2,800 superflares with energies far greater than that of typical solar flares. The scientists say this indicates that Sun-like stars produce superflares roughly once per century."
