Astronomers Witness Historic Launch of Supermassive Black Hole Jet in Real-Time

In a groundbreaking discovery, astronomers have observed the real-time eruption of jets from a supermassive black hole located in the galaxy 1ES 1927+654, approximately 270 million light-years away in the constellation Draco. The black hole, with a mass around 1.4 billion times that of the sun, has launched twin jets of plasma traveling at one-third the speed of light, marking the first time such an event has been captured as it occurs.

The observation was made possible by a collaboration between researchers from the University of Maryland Baltimore County and various radio telescope arrays, including the Very Long Baseline Array. The study revealed emerging structures of highly ionized gas erupting from each side of the black hole, a phenomenon linked to a significant radio flare that began showing early signs in late 2022.

Discovery team leader Eileen Meyer remarked, "The launch of a black hole jet has never been observed before in real-time," emphasizing the importance of this event in understanding how these powerful astrophysical jets develop. The findings were presented at the 245th meeting of the American Astronomical Society and published in The Astrophysical Journal Letters.

The intriguing activity surrounding 1ES 1927+654 began drawing attention in 2018 during an initial outburst, followed by periods of quiescence and further flares. This continuous monitoring allowed scientists to piece together the mechanisms at play in such energetic cosmic giants.
