SouthernWorldwide.com – Researchers have successfully pinpointed the origin of a colossal jet stream, stretching an astonishing 3,000 light-years, emanating from the very first black hole ever to be imaged. This breakthrough was made possible by leveraging the significantly enhanced observational capabilities of the global Event Horizon Telescope network, as detailed in a new study released this week.
The findings, which were published in the esteemed journal “Astronomy & Astrophysics” on Wednesday, promise to shed crucial light on the precise locations and mechanisms by which black holes eject these immense cosmic jets. These powerful streams of particles travel at speeds approaching that of light.
The black hole in question is M87, a supermassive entity residing in the Messier 87 Galaxy. It is situated approximately 55 million light-years away from Earth and possesses a mass equivalent to 6.5 billion times that of our Sun.
The historic first image of M87 was unveiled to the public in 2019, following the data collection efforts of the Event Horizon Telescope in 2017.
Dr. Padi Boyd of NASA elaborated on the significance of this black hole, noting that while most black holes are not actively spewing matter, M87 is an exception. “Just a few percent are active at any given time,” she explained in a video discussing the discovery. “Are they turning on and then turning off? That’s an idea… We know there’s very high magnetic fields that you launch a jet. And so this image is observational evidence that what we’ve been seeing for a while is actually being launched by a jet connected to that supermassive black hole at the center of M87.”
According to publications like Scientific American and Space.com, M87 exhibits a dual nature: it voraciously consumes surrounding gas and dust, while simultaneously expelling powerful jets of charged particles from its poles. These expelled particles are what form the observed jet stream.

“This study represents an early step toward connecting theoretical ideas about jet launching with direct observations,” stated Saurabh, the team leader at the Max Planck Institute for Radio Astronomy, in a statement reported by Space.com. He emphasized the importance of this research.
He further added, “Identifying where the jet may originate and how it connects to the black hole’s shadow adds a key piece to the puzzle and points toward a better understanding of how the central engine operates.” This suggests that the research is crucial for understanding the fundamental workings of these celestial phenomena.
The Event Horizon Telescope is a remarkable collaborative effort, comprising a global network of eight radio observatories. These observatories work in unison to detect faint radio waves emitted by astronomical objects such as galaxies and black holes. By combining their data, they effectively create a virtual telescope with a diameter comparable to that of the Earth.
The term “Event Horizon” itself refers to the boundary surrounding a black hole. Beyond this point, gravity is so intense that nothing, not even light, can escape its pull, as defined by the National Science Foundation.
These groundbreaking findings are based on the analysis of data gathered by the Event Horizon Telescope in 2021. However, the study’s authors acknowledge that while their current results are robust under the employed assumptions and tests, definitive confirmation and more precise characterization will necessitate future observations. These future endeavors will involve higher sensitivity instruments, improved intermediate-baseline coverage through the addition of more stations, and an expanded frequency range for data collection.
