Scientists trace cosmic jet 3,000 light-years to first-ever imaged black hole


Scientists track a 3,000-light-long cosmic jet from First ever image of a black hole A new study published this week shows that the likely source point can be found with the help of “significantly enhanced coverage” from the Global Horizon Telescope.

The findings, published Wednesday in the journal Astronomy & Astrophysics, could help determine exactly where and how black holes launch giant cosmic jets that travel at nearly the speed of light.

M87 is a supermassive black hole located in the Messier 87 galaxy, about 55 light-years away from Earth and 6.5 billion times larger than the sun.

NASA’s Dr. Paddy Boyd explains in a video about the discovery of black holes that not only are they super massive, “they’re also very active.” “Only a few percent are active at any given time. Do they turn on and then off? Here’s an idea… We know there are very high magnetic fields when jets are launched. So this image is observational evidence that what we’ve been seeing for some time is actually being launched by jets connected to the supermassive black hole at the center of M87.”

According to Scientific American and Space.com, M87 both inhales surrounding gas and dust and ejects powerful streams of charged particles from its poles to form jets.

“This study represents an early step in connecting theoretical ideas about jet emission with direct observations,” team leader Saurabh from the Max Planck Institute for Radio Astronomy said in a statement. Space Network.

He added: “Determining where the jet may originate and how it connects to the black hole’s shadow adds a key piece to the puzzle and helps to better understand how the central engine operates.”

The Event Horizon Telescope involves a global network of eight radio observatories that detect radio waves from astronomical objects such as galaxies and black holes, which come together to form an Earth-sized telescope.

According to the National Science Foundation, the event horizon is the boundary of a black hole from which light cannot escape.

The findings were arrived at after examining data from the 2021 Event Horizon Telescope, but the study’s authors added, “While this result is robust under the assumptions and tests performed, clear confirmation and more precise constraints will require future EHT observations with greater sensitivity and improved intermediate baseline coverage through additional sites and expanded frequency ranges.”
