Astronomers Witness Unprecedented Black Hole Activity 270 Million Light-Years Away
In a groundbreaking observation, astronomers have detected a supermassive black hole, located 270 million light-years from Earth in the galaxy 1ES 1927+654, transitioning from a dormant state to a highly active one. This marks the first time scientists have observed such a 'switch on' event during human lifetimes, offering valuable insights into the mysterious behavior of black holes.
The black hole, estimated to have a mass equivalent to 1.4 million suns, began emitting powerful X-rays in late 2022 after years of quietness, immediately followed by a surge of radio emissions. Eileen Meyer, an associate professor of physics involved in the research, emphasized that the rapid change from radio silence to loud emissions was unprecedented.
Recent images captured by radio telescopes revealed jets of plasma blasting from the black hole at nearly one-third the speed of light. Researchers suspect that a previous flare-up in 2018, likely caused by the black hole consuming a star, may have contributed to this new activity.
Astronomers are also exploring the potential presence of a hidden star resisting gravitational pull from the black hole, which could significantly enhance understanding of the interactions between black holes and surrounding matter. This discovery opens up new avenues for research in astrophysics, with the implications of these findings to be published in The Astrophysical Journal Letters.
