An introduction from Science, March 2017: http://www.sciencemag.org/news/2017/03/global-telescope-may-finally-see-event-horizon-our-galaxys-giant-black-hole http://www.sciencemag.org/news/2017/03/global-telescope-may-... "Last year [2015-2016 (2)] researchers "heard" black holes for the first time, when they detected the gravitational waves unleashed as two of them crashed together and merged. Now, they want to see a black hole, or at least its silhouette. Next month, astronomers will harness radio telescopes across the globe to create the equivalent of a single Earth-spanning dish—an instrument powerful enough, they hope, to image black holes backlit by the incandescent gas swirling around them. Their targets are the supermassive black hole at the heart of our Milky Way galaxy, known as Sagittarius A* (Sgr A*), and an even bigger one in the neighboring galaxy M87." (Also see (1)) Now the article in the current main HN link talks about and links to the work just published (2018 May 24, and open access): http://iopscience.iop.org/article/10.3847/1538-4357/aabe2e http://iopscience.iop.org/article/10.3847/1538-4357/aabe2e From the abstract: "The measured nonzero closure phases rule out point-symmetric emission. We discuss our results in the context of simple geometric models that capture the basic characteristics and brightness distributions of disk- and jet-dominated models and show that both can reproduce the observed data." Translated, approximately: "what we see when we analyze the data is something that probably isn't symmetric in all directions and can be either disk-like or has jets." The humanity is "seeing" (using the black hole in the center of our galaxy for the first time! We are looking (combining the radio telescopes across the world as a single telescope and using complex calculations to calculate the results) at the "event horizon" of the black hole in the center of our galaxy, the place from where nothing escapes! And the first picture is blurry but hints on "not point-like." (1) And the current article ends: “The results are an important step to ongoing development of the Event Horizon Telescope”, says Sheperd Doeleman from the Harvard-Smithsonian Center for Astrophysics and director of the EHT project. “The analysis of new observations, which since 2017 also include ALMA, will bring us another step closer to imaging the black hole in the centre of our Galaxy.” --------- 1) Another approachable introduction to what is being done, with a lot of illustrations, is here: https://medium.com/starts-with-a-bang/2018-will-be-the-year-humanity-directly-sees-our-first-black-hole-c20a1429d3e2 https://medium.com/starts-with-a-bang/2018-will-be-the-year-... 2) 2015 collected data, 2016 presented
