Black Hole - First Ever Image Revealed


Black Hole Picture Revealed First Ever

A team of 200 scientist were working on the project. Image was captured by Event Horizon Telescope (EHT), it is a network of eight linked Telescopes.

The supermassive black hole in the core of supergiant elliptical galaxy Messier 87, with a mass ~7 billion times the Sun's, as depicted in the first image released by the Event Horizon Telescope.

What is Black Hole?

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Visible are the crescent-shaped emission ring and central shadow, which are gravitationally magnified views of the black hole's photon ring and the photon capture zone of its event horizon. The crescent shape arises from the black hole's rotation; the shadow is about 2.6 times the diameter of the event horizon .

The information they gathered was too much to be sent across the internet. Instead, the data was stored on hundreds of hard drives that were flown to a central processing centres in Boston, US, and Bonn, Germany, to assemble the information. Prof Doeleman described the achievement as "an extraordinary scientific feat".

"We have achieved something presumed to be impossible just a generation ago," he said.

"Breakthroughs in technology, connections between the world's best radio observatories, and innovative algorithms all came together to open an entirely new window on black holes."
