Astronomers utilizing the groundbreaking Event Horizon Telescope—a global network of eight advanced radio telescopes—have pinpointed the likely origin of a massive space jet emanating from the core of Messier 87.

Messier 87, a colossal elliptical galaxy situated approximately 53 million light-years away in the Virgo constellation, is of great scientific interest.
Also known as M87, Virgo A, and NGC 4486, this galaxy hosts a supermassive black hole, approximately 6 billion times the mass of our Sun.
This supermassive black hole generates a striking, narrow jet of particles that extends roughly 3,000 light-years into the cosmos.
To investigate such distant regions, astronomers are combining radio telescopes from around the world to create a virtual Earth-sized observatory known as the Event Horizon Telescope (EHT).
Using EHT observations of M87 conducted in 2021, researchers assessed the brightness of radio emissions at various spatial scales.
They discovered that the luminous ring surrounding the black hole does not account for all radio emissions, identifying an additional compact source approximately 0.09 light-years from the black hole that aligns with the predicted location of the jet’s base.
“By pinpointing where the jet originates and how it connects to the black hole’s shadow, we are adding significant insights into this cosmic puzzle,” stated Saurabh, a student at the Max Planck Institute for Radio Astronomy and a member of the EHT Collaboration.
“The newly collected data is currently undergoing analysis with contributions from international partners and will soon incorporate additional telescopes, improving our understanding of this area,” remarked Dr. Sebastiano von Fehrenberg, an astronomer at the Canadian Institute for Theoretical Astrophysics.
“This will provide us with a much clearer view of the jet’s launch region.”
“We’re transitioning from merely calculating the positions of these structures to aiming for direct imaging,” he added.
“The jet is postulated to be launched using the rotational energy of the black hole through electromagnetic processes, presenting a unique laboratory where general relativity and quantum electrodynamics intersect,” explained Professor Bert Lipperda, also from the Canadian Institute for Theoretical Astrophysics.
“Studying how jets are launched in proximity to a black hole’s event horizon is a crucial advancement in our comprehension of these cosmic titans.”
“The observational data will empower scientists to test theories regarding the interplay between gravity and magnetism in the universe’s most extreme environments, bringing us closer to understanding the ‘engines’ that shape entire galaxies.”
