 | A massive triple-star system surrounded by dust could be a Wolf-Rayet star, capable of unleashing the greatest release of energy known ... a sustained gamma ray burst.(GRB) Some 8,000 light years from earth, the star system is the first discovered in our own galaxy. Lasting between a few thousandths of a second to a few hours, gamma ray bursts can release as much energy as our sun will release over its lifetime. Long-duration GRBs – longer than 2 seconds – are thought to be caused by the supernova explosions of rapidly-rotating Wolf-Rayet stars. |  |
