An international team of astronomers used supercomputers and computer algorithms to record the first image of Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy.
The Event Horizon Telescope Collaboration (EHT) team employed eight radio telescopes to capture 3.5 petabytes of data including incomplete images of various parts of the black hole.
Supercomputers processed and analyzed the data to produce composite images of Sagittarius A*.
The EHT team said the image released on Thursday represents "an average of the different images the team extracted, finally revealing the giant lurking at the center of our galaxy for the first time."
