NGC 891 - Spiral Galaxy

Sep 21st, 2023

NGC 891 - Spiral Galaxy Is our Galaxy as thin as this one? Probably. The Milky Way, like the galaxy NGC 891 shown in the image, has the typical thickness of a spiral galaxy. In spiral galaxies, most of the bright stars, gas, and absorbing dust are located in a thin disk. These disks are so thin that a spiral galaxy seen edge-on resembles a compact disc. The dark band running through the middle is a layer of dust that absorbs light. Some stars orbiting the center of NGC 891 follow trajectories that are far from circular. Why do these stars move so strangely? According to one hypothesis, a large bar runs through the center of this galaxy, which we would see if it were face-on rather than edge-on.
