Peer Into The Abyss: A Virtual Telescope Could Possibly Capture The First Ever Black Hole Image!

Space is one of the most interesting topics ever known to humankind. Along this, black holes are specifically controversial probably because of its lack of visual representation.  Physicist, Karl Jansky, first presented an evidence of a black hole in 1931 when he discovered radio waves coming from the centre of our galaxy. This has sparked the interest of different scientists on exploring such. Today, different books and theories like Stephen Hawking’s taught us that black holes, as the name implies, are extremely dark. With their massive size, they're known to irreversibly consume everything that crosses their horizon, including light. This caused difficulties in seeing, more so capturing an image of it. To say bluntly, it was deemed impossible to capture a black hole's image for a very long time. Fortunately, scientists recently developed a ‘virtual telescope’ named Event Horizon Telescope in hopes of being able to see, for the first time ever, a black hole not to mention photograph it! Specifically, scientists have built this telescope to observe a supermassive black hole called Sagittarius A. This certain black hole is 26,000 light-years from Earth and is probably around 20 million kilometres across which means it’s only about the size of a pinprick in our night sky. Moreover, the telescope works using a technique known as very-long-baseline interferometry (VLBI), relying on a network of radio antennas all over the world, from the South Pole, to Hawaii, to the Americas and Europe. Since these antennae all tuned in on a single spot, the resolution of the telescope should be 50 microarcseconds, which is equivalent to being able to see a watermelon on the surface of the Moon, enabling us to see the black hole from Earth. Scientists have planned to switch this telescope on between the 5th to 14th of April and test Einstein's theory of gravity. This can help us understand further the concept of basic physics. From Pluto's vivid heart and now a black hole to look forward to! Safe to say, amidst the Kardashian's constant nonsense chaos, the humanity really is advancing. http://www.dailymail.co.uk/sciencetech/article-4234572/We-image-BLACK-HOLE.html
