Blazar OP 313 Identified as Most Distant Black Hole Beacon from Cosmic Dawn
Astronomers have identified Blazar OP 313 as the most distant and earliest blazar ever detected, providing a rare glimpse into the universe's high-activity phase. This object features a supermassive black hole emitting plasma jets directly toward Earth, with light that has traveled for 8 billion years. The discovery offers critical insights into the 'cosmic noon' era, a period of intense galaxy formation that occurred roughly 5 billion years after the Big Bang.
