From NASA in the USA:
This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own galaxy.
“This was a truly monstrous explosion, a hundred times more energetic than a typical supernova,” said Nathan Smith of the University of California at Berkeley, who led a team of astronomers from California and the University of Texas in Austin.
“That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun. We’ve never seen that before.”
