“Chaos Central” -Huge Nebulous Ring Observed Around Milky Way’s Black Hole


Accretion Disk of Milky Way Supermassive Black Hole


Through decades of study, astronomers have developed a clearer picture of the chaotic and crowded neighborhood surrounding the supermassive black hole, Sagittarius A*, at the center of the Milky Way — a region dense with roving stars, interstellar dust clouds, and a large reservoir of both phenomenally hot and comparatively colder gases. These gases are expected to orbit the black hole in a vast accretion disk that’s siphoning material extending a few tenths of a light-year from the black hole’s event horizon. (more…)
