Goddard TV Video Tape: G2014-041 -- M Dwarf Super Flare



NASA's Swift mission detected a record-setting series of X-ray flares unleashed by DG CVn, a nearby binary consisting of two red dwarf stars, illustrated here. At its peak, the initial flare was brighter in X-rays than the combined light from both stars at all wavelengths under normal conditions.   Credit: NASA's Goddard Space Flight Center/S.
