A total of 370 observations made by the Chandra X-ray observatory are concentrated in a striking image of the “center” of the Milky Way published this Friday by NASA. reports AP.
The graph depicts billions of stars, as well as numerous black holes at the heart of our galaxy, located at 26,000 light years from Earth. To contrast it, the specialists turned to a radio telescope located in South Africa.
“What we see in the image is a violent or energetic ecosystem in the center of our galaxy. There are many remnants of supernovae (stellar explosions), black holes, and neutron stars. Each X-ray point or feature represents an energy source, most of which are in the center, “said Daniel Wang, an astronomer at the University of Massachusetts (USA), who required a whole year to complete the work, conducted while he was staying at home because of the pandemic.
The Chandra X-ray observatory is an active artificial satellite launched by the US space agency on July 23, 1999. Such devices were sent into space because the Earth’s atmosphere absorbs most X-rays, so that conventional telescopes cannot detect them.
