Mysterious Signals From Deep Space Hint at Something Brutal, Scientists Say
Astronomers believe they've uncovered the source behind mysterious cosmic signals known as fast x-ray transients (FXTs) — and it's something absolutely brutal. Right as a massive star explodes in a supernova, it unleashes a tremendously energetic stream of particles that travel at near light speed called a jet, producing a gamma ray burst — one of the most powerful explosions in the universe. The rest of the star, typically, collapses into a black hole. But a pair of new studies suggests that this last gasp by a star before winking out of existence can get "trapped" by some of the […]
