The area around Sagittarius A*, the supermassive black hole at the center of the Milky Way, seen in polarized light
Two articles published in “The Astrophysical Journal Letters” report different aspects of a study of Sagittarius A*, or simply Sgr A*, the supermassive black hole at the center of the Milky Way, which led to the creation of an image in polarized light of the area around it. The Event Horizon Telescope (EHT) collaboration used again a combination of various radio telescopes to detect polarized light thanks to the fact that particles rotating around the magnetic field lines determine a polarization pattern perpendicular to it.
