Watch and read the full coverage of Powehi: The first black hole pictured by Mankind. The information provided in this article is based on the unveiling by the scientists and Shep Doeleman, the director of the Event Horizon Telescope. Hence all the facts hold absolutely true. This content may be changed in the future as we only share genuine articles to our fellow readers. So sit back with a cup of tea or coffee as this is gonna take some time of your precious life but gonna open your perspective about some of the events that are happening in space.
As we all know that space is one of the things that mankind hasn’t been able to fully exploit nor understand as it is way beyond our reach in terms of technology as well as our understanding in Physics. But as we are highly advanced and an intelligent form of life, we have already achieved the technology that can give us a snapshot of an object which is millions of light years away from us. Hence it is just a matter of time when we embark new and life-altering technology or knowledge about the vast and the unexploited area of the universe.
News about Powehi: The first black hole pictured by Mankind
Earlier this week on Wednesday, the first picture of a black hole was unveiled by which led many scientists thrilled and excited as it might give us a chance to know a lot more about one of the most mysterious objects in the universe.
Shep Doeleman, director of the Event Horizon Telescope which we will know later quoted that seeing the first ever reconstructed image of a Black Hole millions of light years ahead is “A once-in-a-lifetime result & opportunity,” which their scientists could produce by the Event Horizon Telescope.
What is an Event Horizon? Powehi: The first black hole pictured by Mankind
In general relativity, an event horizon is a region in spacetime beyond which events cannot affect an outside observer. In layman’s terms, it is defined as the shell of “points of no return”, i.e., the boundary at which the gravitational pull of a massive object becomes so great as to make escape impossible. Read more
What is the Event Horizon Project?
The Event Horizon Telescope (EHT) is basically a large telescope array consisting of a global network of radio telescopes and combining data from several very-long-baseline interferometry (VLBI) stations around the Earth. The aim of the project is to observe the immediate whereabouts of the supermassive black holes, with an angular resolution that is high enough to resolve structures on the size scale of the black hole’s event horizon.
The image also shows the boundary between the light and the dark around the black hole which is called the Event Horizon or the Point-Of-No-return. At the center of the monsterous Black Hole where the time and space becomes so curved on themselves that the laws of Physics don’t hold true. Read more
What is a Black Hole? The first black hole pictured by Mankind
A black hole is a region of a spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. Read more
The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958.
There is a reason why pictures express a lot better than words !!
The astonishing snapshot shows a massive black hole around 55 million light years away from Earth which is in our neighboring galaxy Messier 87 or M87 which was nicknamed Powehi. The black hole is 6.5 billion times as massive as our Sun and its diameter is 24 billion miles. Its gravitational force is so powerful that even the light particles cannot cast away. It is basically like a point of no return. the powerful gravity and the mass casts a shadow against the bright hot gas which keeps swirling around it giving it a donut-like shape from the perspective of the Event Horizon Telescopes.
Why “Powehi”? The first black hole pictured by Mankind
Pōwehi is a word from Hawaiian mythology which means “embellished dark source of unending creation” which is also pronounced as “pow-vay-hee”. It was nicknamed on the first ever black hole which was spotted and pictured by the humans was given by astronomers and Larry Kimura, a renowned Hawaiian language professor. The source of the word Powehi came from the Hawaiian word “Kumulipo” which is a primordial chant describing the creation of the universe. ‘Po‘ means a profound dark source of the unending creation whereas ‘wehi‘ is one of the many descriptions of “Po” in the chant. As it was the first black hole pictured by mankind and was named Powehi. Hawaii was the reason behind the nickname of this black hole as most of the scientists who helped to get this project successful were from Hawaii.
“This major scientific achievement marks a paradigm shift in our understanding of black holes, confirms the predictions of Albert Einstein’s General Theory of Relativity and opens up new lines of inquiry into our universe,” due to Powehi: The first black hole pictured by Mankind.
