Milky Way's centre exploded 3.5 million years ago
A cataclysmic energy flare ripped through our galaxy, the Milky Way, about 3.5 million years ago, a team of astronomers say. The so-called Seyfert flare started near the supermassive black hole in the centre of the galaxy, they add. The impact was felt 200,000 light-years away. The discovery that the Milky Way's centre was more dynamic than previously thought can lead to a complete reinterpretation of its evolution.
