New supernova mechanism would set off repeat explosions.
A new type of ultra powerful supernova discovered last year may blow its top again, according to a new study. Researchers report that supernova 2006gy fits a model of star explosion that should have produced two flare-ups already and may culminate in a third before the star fizzles out.
A second study proposes that the explosion might have come about from the marriage of multiple stars.
SN 2006gy first caught astronomers' eyes in September. Burning 100 times brighter than a typical supernova, it maintained full strength for an amazing three months, by which point most of its counterparts would have begun fading.
