There'sa dragon dozing in the Milky Way's core. Hidden from sight by our galaxy's dusty disk, a supermassive black hole sleeps fitfully. Sometimes a cloud of gas might whisk around its nostrils or a star fall on its head and make the dragon snort a bit of flame, thenC Carlisle...
The upcoming cosmic spectacle should offer scientists a chance to test some of their theories about how black holes accrete mass

A growing body of evidence, including observations that produced the first image of Sagittarius A*, is starting to reveal the inner workings of our Galaxy’s core. By Davide Castelvecchi The Atacama Large Millimeter/submillimeter Array in Chile is one of the observatories in the Event Horizon Te...
particular wavelength of light which is given off when hydrogen gas ionizes and which can reach all the way to Earth. They were able to detect these radio signals and use this data to produce the first image of the gas disk, as well as seeing how the gas rotates around the black hole...
The Event Horizon Telescope’s image of our Milky Way’s supermassive black hole, at a wavelength of 1.3mm. (Image credit: EHT Collaboration) The intention now is to apply this breakthrough while taking new images of Sagittarius A* and the supermassive black hole in M87. "The time is righ...
