They shared their findings earlier this month in the Astrophysical Journal. Astronomers Catherine Zucker, Cara Battersby and Alyssa Goodman argue that the Milky Way's spiral arms are organized around distinct skeletal features. They describe these features, or bones, as long, thin, high-contrast filaments of cold, dark clouds of gas and dust. The filaments can ... read more
