Astronomer som har brukt teleskopene til European Southern Observatory (ESO) har oppdaget gigantiske flekker på overflaten til ekstremt varme stjerner gjemt i stjernehoper. Ikke bare er disse stjernene plaget av magnetiske flekker, noen opplever også superflares, som er eksplosjoner av energi flere millioner ganger mer energiske enn lignende utbrudd på solen. Funnene, publisert i Nature Astronomy i dag, hjelper astronomer med å forstå disse underlige stjernene bedre, samt åpne dørene for å løse andre unnvikende [...]
