A binary star known as KIC 9655129 observed by NASA’s Kepler space telescope is known to produce superflares, thousands of times more powerful than those ever recorded on the Sun. Research led by the University of Warwick suggests the underlying physics of KIC 9655129’s superflares and solar flares might be the same, supporting the idea that our Sun could also produce such phenomena.
The Sun emitted a mid-level solar flare, peaking at 8:33am BST on 24 August 2015. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured the image of the event shown here. Although harmful radiation from such a flare cannot pass through Earth’s atmosphere, intense flares can disturb the atmosphere in the layer where GPS and communications signals travel.
