An X-ray image of Sagittarius A*, the supermassive black hole at the center of the Milky Way, taken by the Chandra space observatory. The image was created from the longest exposure of the region at the time of its creation, and revealed more than 2,000 X-ray sources alongside Sagittarius A*. The research described in the article was not based on the Chandra image, but on infrared observations using ERIS on the Very Large Telescope. Credit: NASA/CXC/MIT/FK Baganoff et al.
