See the Milky Way's Sagittarius A* black hole in an amazing polarized Event Horizon Telescope image - Space.com - astrophysics
A view of Sagittarius A*,the supermassive black hole at the centre of our Milky Way galaxy,is presented by the European Southern Observatory (ESO).It was taken by the Event Horizon Telescope,a global network of radio telescopes including one operated by ESO at Atacama,Chile.The new polarised image of Sgt A* is similar to the image of the supermassive black hole at the centre of the M87 galaxy because they both have strong magnetic fields.Despite what the video says,Sagittarius A* is in a quiescent mode now,not eating much of anything.Credits:ESO,University of Arizona

Sagittarius A*: NASA Telescopes Support Event Horizon Telescope in Studying Milky Way's Black Hole - the first ever photo of our own black hole
Sagittarius A*: NASA Telescopes Support Event Horizon Telescope in Studying Milky Way's Black Hole: Multiple telescopes, including Chandra, observed the Milky Way's giant black hole simultaneously with the Event Horizon Telescope (EHT). This combined effort gave insight into what is happening farther out than the field-of-view of the EHT.
