A model of accretion on a disc-shaped galaxy. Color represents the temperature of the gas, and the black lines the flow lines of the gas, when it flows from the hot galactic surrounding medium (about a million degrees) to the galaxy where the gas is relatively cold (about 10,000 degrees). The right panel shows three streamlines in 170D, which highlight the swirling of the gas during the inflow. The top image is a Hubble Space Telescope image of a relatively nearby disk galaxy. Its diameter is about 21 thousand light years, and its distance from us is about XNUMX million light years.
