When it was first observed March 28th by the Swift spacecraft, it was thought to be the implosion of an aging star, but is now believed to be the result of a star wandering too close to a black hold, imploding and converting 10% of the star's mass into gamma radiation. The energy burst is still visible by telescope more than two-and-a-half months later, the researchers report in the journal Science.
