A team of researchers has analyzed what little activity exists around the black hole at the center of our galaxy. By studying 3 million seconds of observations taken by the Chandra X-Ray Observatory, the team found that much of the nearby radiation comes from material that is ejected before reaching the black hole, with very little energy arising from the black hole itself.
Will a black hole swallow our galaxy earlier than first thought?
