Astronomers discover ultrapowerful black hole jet as bright as 10 trillion suns lit by Big Bang's afterglow

Astronomers have spotted an insanely bright black hole jet—so powerful it shines with the equivalent of 10 trillion suns. The jet’s light is amplified by the cosmic afterglow of the Big Bang, making it visible despite the black hole’s mind-bending distance. Researchers describe the challenge of detecting it as "looking for candlelight next to a flashlight blasting straight at us."
