Astronomers spot mysterious gamma-ray explosion, unlike any detected before

Astronomers have detected an explosion of gamma rays that repeated several times over the course of a day, an event unlike anything ever witnessed before. The source of the powerful radiation was discovered to be outside our galaxy, its location pinpointed by the European Southern Observatory’s Very Large Telescope (VLT). Gamma-ray bursts (GRBs) are the most powerful explosions in the Universe, normally caused by the catastrophic destruction of stars. But no known scenario can completely explain this new GRB, whose true nature remains a mystery.

Ta, interesting. Massively violent event, I hope no-one was hurt.

:)

Good. More unexplained stuff for great intellects to work on. Keeps them off the street, which is a good thing.

Could a star gravitationally attract enough material from a companion its goes nova multiple time a day

I doubt that.
