Astronomers believe that most gamma-ray bursts are caused by giant stars exploding as supernovae and leaving behind a black hole remnant. But a recent burst in 2024 had some strange behaviors that don't match the standard model of black holes. In a recent paper, a team of astronomers proposed that something more interesting happened: a massive star collapsed to form a magnetar, which then had a phase transition to become a "strange star" made of strange quark matter.
