Astronomers have identified a new structure in the Milky Way: a long tendril of dust and gas that they are calling a “bone.”
“This is the first time we’ve seen such a delicate piece of the galactic skeleton,” says the lead author Alyssa Goodman of the Harvard-Smithsonian Center for Astrophysics (CfA). Goodman presented the discovery Jan. 8 in a press conference at a meeting of the American Astronomical Society in Long Beach, Calif.
Our Milky Way is a spiral galaxy — a pinwheel-shaped collection of stars, gas, and dust. It has a central bar and two major spiral arms that wrap around its disk. Because we view the Milky Way from the inside, its exact structure is difficult to determine.
