🌌 Astronomers just detected the most distant blazar ever observed, and its light has been traveling toward us for 8 billion years.
Known as Blazar OP 313, it’s powered by a supermassive black hole feeding on surrounding material and launching jets of plasma at nearly the speed of light. Because one of those jets points almost directly toward Earth, we see an especially intense burst of energy.
The light reaching us today shows the blazar as it existed about 5 billion years after the Big Bang, when stars and galaxies were forming at an extraordinary pace.
🔭 By studying its high-energy gamma rays, researchers can learn more about how supermassive black holes accelerated particles and shaped their surroundings during an earlier chapter of cosmic history.
Eight billion years later, that ancient signal is still teaching us something new about the universe. ✨
"Around 11 billion years ago, the universe experienced a period of peak activity known as the 'Cosmic noon,' characterized by an intense rate of star and galaxy formation."
