The global network of telescopes has essentially created a planet-sized observational dish.If you want to be caught up even more, here's the Press Association's round-up of what's going on today:Astronomers are expected to reveal the first close-up images of a monster black hole during a global event later.Eight radio telescopes around the world have been pointed at two of the cosmic behemoths, one at the heart of our galaxy, the Milky Way, and another nearly 54 million light years away.Now, after two years of acquiring and processing the data, the international team of scientists at the Event Horizon Telescope (EHT) programme is set to present their "ground-breaking" first results.Media have been told to gather for press conferences in Brussels, Washington, Santiago, Shanghai, Taipei, Tokyo, and Lyngby in Denmark that are due to begin at around 2pm BST.Black holes are regions where matter has been crushed by gravity to an infinitely small space where the normal laws of physics no longer apply.While nothing can escape the gravitational vortex of a black hole - not even light - gas and radiation rage in a swirling eddy around the brink of the abyss.It is this point-of-no-return precipice, called the Event Horizon, that astronomers have tried to observe for the first time.Sagittarius A (SgrA), the supermassive black hole at the centre of the Milky Way, is some 26,000 light years away.Images of SgrA are likely to show a lopsided ring of brightness due to gravity bending light closer to the black hole more strongly than light further away.The project may help scientists struggling to marry together two apparently incompatible pillars of physics, Einstein's theory of general relativity and quantum mechanics.The first relates to laws of nature on cosmic scales, while the second governs the weird world of subatomic particles where it is possible to be in two places at once.Physicist and black hole expert Lia Medeiros, from the University of Arizona, US, told ScienceNews magazine: "If general relativity buckles at a black hole's boundary, it may point the way forward for theorists. Among those due to speak are astrophysicist Sheperd Doeleman, director of the Event Horizon Telescope at the Center for Astrophysics, Harvard & Smithsonian.The research will test the theory of general relativity put forward in 1915 by Einstein, the famed theoretical physicist, to explain the laws of gravity and their relation to other natural forces.Einstein's theory allows for a prediction of the size and shape of a black hole. But in the meantime have a look at that jet the galaxy is throwing out.It comes out of the galaxy's core extends over thousands of light years.

There’s simply no way to send that much data efficiently over the internet. ";s:7:"keyword";s:27:"Black hole image size in gb";s:5:"links";s:4517:"Colton's Deep Cover,
