An article published in the journal “Astronomy & Astrophysics” describes the detection of very hot gas clouds that orbit the supermassive black hole at the center of the Milky Way, called Sagittarius A* or simply SgrA*. A team of researchers used the GRAVITY instrument installed on ESO’s VLT to observe infrared light flares coming from the gas and dust accretion disk that orbits SgrA* at very high speed. These are the most accurate observations of materials so close to a black hole’s event horizon.
