“A composite image of the region around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way. X-ray emission from NASA’s Chandra X-ray Observatory is shown in blue, and infrared emission from the Hubble Space Telescope is shown in purple and yellow. The inset shows a close-up view of Sgr A* in X-rays only, covering a region half a light year wide. The diffuse emission is from hot gas captured by the black hole and being pulled inwards. Less than 1% of this material reaches the black hole’s event horizon, or point of no return, because much of it is ejected.”
