An article published in the journal “The Astrophysical Journal Letters” reports the results of observations of a structure similar to a chimney which functions as a sort of vent from which hot gas coming from Sagittarius A*, the supermassive black hole at the center of the Milky Way, escapes. A team of researchers combined observations conducted in X-rays with NASA’s Chandra Observatory and radio waves with the MeerKAT radio telescope to pinpoint that vent, which is located at about 700 light-years from the center of the Milky Way. This helps reconstruct the processes in which Sagittarius A* swallows materials and re-emits some of them.
