| Black hole |
It is the first-ever image of Blackhole. This image of "Ring of fire" black hole was photographed 55 million light-years away from Earth in the galaxy Messier 87. Astronomers on Earth linked eight powerful radio telescopes to snap what is essentially the shadow of the black hole, cast by the glowing clouds of gas around it. This news was published on Wednesday, April 10, across six scientific papers in the journal The Astrophysical Journal Letters. It is the first image because before this all image was created on a computer. Shepherd S Doeleman was the head of the Event Horizon Telescope (EHT) project. This is an extraordinary scientific feat accomplished by a team of more than 200 researchers. Since the discovery was made, astronomers at the James Clerk Maxwell Telescope on Mauna, Hawaii, have named the black hole Powehi. The Hawaiian name, when translated, means the adorned fathomless dark creation or embellished dark source of unending creation. The terrifying name was suggested by professor Larry Kimura of the University of Hawaii-Hilo.
Now the question is why this image is so important?
Because taking a picture from the earth with only one radio telescope was not possible. It would only take only one part of it. So scientists set radio telescopes in the earth to take the full image of "Ring of fire" black hole. those radio telescopes were set around the world, from the United States to Mexico to Chile to the South Pole, observing the same targets at the same time. So it was not as easy as taking a photo with a mobile.
