“Baffling Superflares” –Revealed by Kepler Mission at Edges of the Milky Way

Milky Way Galaxy


A threat to Earth? Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy –superflares, that occur when stars, for reasons that scientists still don’t understand, eject huge bursts of energy that can be seen from hundreds of light years away. Until recently, researchers assumed that such explosions occurred mostly on stars that, unlike Earth’s, were young and active.
