A team of researchers that has members from all over the world is now preparing to design what might be one of the first pictures of black hole. The project came in as a consequence of collaboration between teams that have radio receivers all over the world. A team of MIT has been working to assort data from all other teams and will most probably formulate an image. The project has been going on from last two decades as the members are now piecing together what is named as Event Horizon Telescope (EHT). There are 12 radio receiving teams that are participating in this experiment and every single one of them will be using the device that has been installed for this project to register data that is being received at a frequency of 230GHz. The data will be registered over hard drives all of which will be sent back to MIT Haystack Observatory located in Massachusetts, here, a team will stitch the data together with a technique known as very long baseline array interferometry, forming the illusion of a single radio telescope which is as large as size of our planet Earth. It will focus on what is believed to be a black hole that is located at the center of Milky Way galaxy – Sagittarius A.
It is not possible can never be photographed because light cannot escape or reflect. Therefore, you cannot click the light that is all around the black hole that is present over its borders before vanishing. Sagittarius A* is located at a distance of some 26, 000 light years from our planet and has mass of approx. 4 million times more than that of Sun. it is also being assumed that the event horizon of this black hole is approx. 12.4 million miles across. Instead of its large size, it will be much more smaller than a small pebble in our sky which brings in the requirement for an arrangement of radio telescopes.
