In an article in the journal Nature, scientists reported that they had used images from NASA’s Chandra X-ray Observatory to reveal how objects in the most active area of the Milky Way Galaxy affect each other and other parts of the galaxy. The scientists had used 30 separate images from Chandra to construct a montage of the Milky Way’s central regions, revealing hundreds of white dwarf stars, neutron stars, and black holes, shrouded by the extremely hot gas around a massive black hole. The researchers found that emissions from highly ionized iron, previously attributed to diffuse hot gas, had actually originated from discrete sources in the Milky Way’s white dwarf stars, neutron stars, and black holes. The findings helped clarify the relative contributions of diffuse and discrete sources of x-rays emitted from the galaxy.
