Scientists Say They Can't Explain the Signal They Just Detected From Beyond Our Galaxy
Gamma ray bursts are some of the most powerful explosions in the universe, unleashing as much energy in mere seconds as the Sun will in its entire 10 billion year lifespan. Typically, they're produced by stars dying in a spectacular supernova — a rapid collapse that completely obliterates the stellar object. But now, astronomers say they've detected a gamma ray burst that utterly defies explanation: it repeated multiple times over the course of a single day, as if the star somehow suffered back
