Nasa's Swift satellite has seen a giant flare explode from a nearby star.
Our Sun also flares when twisted magnetic field lines in the solar atmosphere suddenly snap - but this was on a far bigger scale, scientists say.
The energy released by the II Pegasi star was equivalent to about 50 million trillion atomic bombs, they calculate.
