Astronomers report a strange cosmic blast that looked like a kilonova, then behaved like a supernova, hinting at a possible first “superkilonova” and leaving scientists debating how stars truly die.

Columbia Professor Brian Metzger helped other astronomers interpret their observations of the unexpected stellar event.

A double explosion, in which a dying star split, then recombined, may be a long-hypothesized but never-before-seen "superkilonova." ...
