Doyle Rice USA TODAY Published 3:52 PM EDT Apr 12, 2019 We've seen humanity's first photo of a black hole. Is the adventure over? No. Far from it: "The researchers who captured the first-ever images of a black hole don't plan to rest on their laurels," Space.com said. Astronomers agree that their work is far from done, project director Sheperd Doeleman of Harvard University said at a news conference Wednesday. It is actually only just beginning. Scientists this week unveiled the first picture of a black hole, which was located at the center of Messier 87, a massive galaxy in the "nearby" Virgo galaxy cluster. It looked like a flaming orange, yellow and black ring. Images came from a collection of eight telescopes around the world specifically designed to peer at black holes, part of the Event Horizon Telescope project. The telescopes are in Chile, Hawaii, Arizona, Mexico, Spain and at the South Pole. Though the image was a monumental … [Read more...] about Black hole first photo: We’ve got the first image, what happens now?
How are black holes made
Astronomers have revealed the first ever close-up photo of a black hole during a groundbreaking global event. 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 have presented their first results. Media gathered for press conferences in Brussels, Washington, Santiago, Shanghai, Taipei, Tokyo and Lyngby in Denmark from 2pm. Follow our live updates below...

ASTRONOMERS are set to reveal the first ever image of a black hole later today. The Event Horizon Telescope has been carrying out an international mission to photograph a black hole and its first results will be presented this afternoon. Current theories suggest that black holes are invisible but have a gravitational pull so strong that they suck in light, which leaves the area around them distinguishable and a black circle shaped void in the middle. It is widely thought that every galaxy has a supermassive black hole at its centre, including the Milky Way. The cosmic material which is in close proximity to the edge of a black hole is thought to spin so fast that it actually emits radiation. The Event Horizon Telescope is made up of a series of radio telescopes which are positioned all over the world. It has been working on this black hole project over the last 13 years. All of the telescopes involved have been trained to focus on Sagittarius A*, a bright source of radiation at … [Read more...] about Scientists will unveil first ever picture of a black hole in groundbreaking discovery today
Astronomers are poised Wednesday to unveil the first direct image of a black hole and the surrounding whirlwind of white-hot gas and plasma inexorably drawn by gravity into its ravenous maw, along with the light they generate. The picture will have been captured by the Event Horizon Telescope (EHT), a network of eight radio telescopes scattered across the globe. Paul McNamara, an astrophysicist at the European Space Agency and project scientist for the LISA mission that will track massive black hole mergers from space, helped AFP put what he called an "outstanding technical achievement" into context. How do we know black holes exist? "We think, of course, of a black hole as something very dark. But the mass it sucks in forms a so-called accretion disk that gets so hot it glows and emits light. Over the years, we accumulated other indirect observational evidence -– X-rays coming off objects, for example, in other galaxies. In September 2015, the LIGO gravitational wave … [Read more...] about Black holes: picturing the heart of darkness
