Black Hole Picture: What is the brightness accretion disk around the M87 black hole?
Black Hole picture: Scientist has taken an awe-inspiring photograph of a supermassive black hole for the first time in history. What is the glowing disc of light around the black hole?
Astronomers at the Event Horizon Telescope (EHT) have produced the world’s first image of a black hole 55 million light-years away from Earth. The monumental discovery concludes 2 years of intense work. During which scientists connected eight powerful radio observatories around the world in one device. The monstrous part, was photographed at the heart of galaxy Messier 87 from a distance of 323,324,400,000,000,000,000 miles (520,340,180,000,000,000,000km). Shepherd S Doeleman, EHT project director, said: “We have taken the first picture of a black hole.
“This is a rare scientific accomplishment accomplished by a team of quite two hundred researchers.”
In the center of the groundbreaking image is a dark, round shadow, which it is the monstrous black hole’s event horizon.
The event horizon is the point of no return, past which all matter, including light, falls towards the black hole’s infinitely compressed singularity.
Surrounding the black hole is a bright, glowing ring of light known as the accretion disc.
The accretion disc could be a superheated cloud of gas and cloud spinning around the event horizon.
The gravity inside of a black hole is too powerful for any light to escape past the event horizon.
But the accretion disc itself is immensely bright and releases vast amounts of electromagnetic radiation, such as x-rays, radio waves, and infrared beams into space.
Pinpointing the location of an accretion disc is the key to mapping the black hole it orbits.
Ultimately, some of the material within the accretion disc will be drawn into the black hole while other parts are shot out into space as so-called relativistic jets.
These jets of cosmic material can extend into the depths of space for thousands of light-years.
In essence, the EHT scientists photographed the shadow of the black hole cast by the accretion disc.
Council Heino Falcke, chair of the EHT science council, said: “If immersed in a bright region. Like a disc of glowing gas, we expect a black hole to create a dark region the same as a shadow. One thing expected by Einstein’s general theory of relativity that we’ve ne’er seen before.
Black Hole Picture: Nothing will come back once it passes the dark event horizon
“This shadow, caused by the gravitational bending and capture of light by the event horizon, reveals a lot about the nature of these fascinating objects and allowed us to measure the enormous mass of M87’s black hole.”
According to NASA, the EHT accomplishment is a testament to human ingenuity and engineering.
Paul Hertz, director of the uranology division at NASA Headquarters in Washington. Said: “This is an amazing accomplishment by the EHT team.
“Years ago, we have a tendency to thought we might have to be compelled to build an awfully giant area telescope to image apart.
“By obtaining radio telescopes around the world to figure together like one instrument. The EHT team achieved this, decades prior time.”
