The Horizon Telescope (EHT) captured stunning, newly revealed images of supermassive black holes in the heart of the Galaxy M87. EHT made this black hole known as M87*, famous for 2019. April, when it was revealed as the first black hole ever depicted by humanity.
These m87*images of about 55 million light -years from the Earth show that the polarization of magnetic fields around the black hole in four years. New M87* observations also show signal signal signal materials of the material of the materials from the black hole, its base connected to a bright ring around the outer boundary or “horizon of the event”, approximately m87*.
Images could help scientists continue to develop theories, how the material behaves in extreme environments around the supermassive black holes, which are a mass of millions or even billions of sun, and are in the hearts of all large galaxies.

“The fact that the polarization model was directed from 2017 to 2021 was completely unexpected,” said Jongho Park, a member of the Kyunghee University, South Korea University, said in a report. “It challenges our models and shows that there is a lot that we still don’t understand near the horizon of the event.”
Observations showed overheated, highly magnetized gas or plasma rings flowing to one side around this 6.5 billion monos-masse black hole in 2017, then arranged in 2018, before 2021, in the opposite direction in the opposite direction.
“It is surprising that the size of the ring remained consistent over the years, confirming the shadow of the black hole predicted by Einstein’s theory [of general relativity]The polarization model is changing significantly, ”said Paul Tiede, a team of astrophysics center astronomy | Harvard and the Smithsonian Center astronomer. This says that the magnetized plasma, which turns near the horizon of the event, is far from static;

The changing plasma around the M87* Polarization seems to indicate an evolving and restless environment around this black hole, which can affect how it feeds on surrounding materials. The reason for baking is not yet clear, but this may be the result of the plasma magnetic structure, along with external influences.
The newly released images also allowed the team to enter the house with a particle nozzle base, for the first time with the EHT almost light speed when the EHT for the first time. It is believed to be an important breakthrough, as nozzles such as this that consists of particles directed at black hole poles in magnetic fields reflect one of the ways as supermassive black holes pull the galaxies in which they sit, pumping a huge amount of energy to their surroundings.
New images also illustrate the changes that EHT itself has experienced. The last image collected in 2021 is sharper due to the fact that in Arizona and Noema (Northern Extended Millimetter) in France added two new telescopes, Kitt Peak and Noema (Northern Extension Milimeters) to 25 Earth and cosmic instruments that make up the EHT network.
“These results show how EHT turns into a full -fledged scientific observatory that can not only provide unprecedented images, but also to create a progressive and consistent understanding of black hole physics,” said EHT scientist Mariafelicia de Laurentis, Naples Federico II Italian. “Each new campaign expands our horizons, from the dynamics of plasma and magnetic fields to the role of black holes in space evolution. This is a specific evidence of the scientific potential of this instrument.”

Future images from the EHT are improved due to two updates to their network telescopes, Greenland’s telescope and James servant Maxwell’s telescope. So EHT will continue to play a crucial role in understanding the Black Hole physics for the coming year, team members said.
“Year after year, we refine ehht to use additional telescopes and improved instruments, new ideas for scientific research and new algorithms to get more data,” said team associate Michael Janssen from the University of Radboud in the Netherlands. “In this study, all of these factors have been beautifully involved in new scientific results and new questions that will really take us for many years.”
Team study was published in August magazine edition Astronomy and astrophysics.
