Solar flares 10,000 times stronger than any ever observed on our sun can be released by stars similar to ours, according to new research.
Just one solar flare of that magnitude would greatly damage the ozone layer, and cause mass extinctions.
The largest flares were coming mostly from stars that appeared to have massive sunspots, larger than any ever observed on our sun.
“Most superflare stars have large starspots, but the present sun does not,” Hiroyuki Maehara, an astronomer at Kyoto University, and the lead author of the paper, is quoted as saying. “Further studies are necessary to understand why and how such large starspots are formed on solar-type stars, and whether our sun can produce superflares.”
