Astronomers have found young and active stars ejecting what they call superflares. Superflares are like the solar flares from our Sun, but are hundreds to thousands of times more powerful. A team of astronomers says they have found evidence that stars as old as our 4.6 billion year old Sun are also capable of blasting superflares every several thousand years. Should the Sun eject a superflare, the astronomers say that it could wreak havoc with electronic devices around the world, cause widespread power blackouts and cause communications satellites to be taken out of commission.
