Record-smashing 'superflare' observed by satellite

It’s time to update the list of record-setting space phenomena. NASA’s Swift satellite has recorded a stellar flare from a nearby red dwarf that is at least 10,000 times bigger than the previous record. The “superflare” was also the longest lasting and hottest on record, reaching about 200 million degrees Celsius, making it 12 times hotter than the center of our sun, redOrbit reports. The flare originated from a binary star system a mere 60 light-years away called DG Canum Venaticorum, but it’s unclear which of the red dwarfs actually emitted the flare.

*Correction, 2 October, 3:01 p.m.: This item originally stated that NASA’s Swift satellite has recorded a “solar” flare. It has been updated to say “stellar” flare.
