In collaboration with domestic and international research institutions, the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has leveraged China's Five-hundred-meter Aperture Spherical Telescope (FAST) to achieve a groundbreaking observation. For the first time, they have revealed a sophisticated network of filamentary structures, primarily driven by supersonic turbulence, within a cluster of interstellar gas clouds racing through the Milky Way at ultra-high speeds. This revelation offers a fresh perspective on the early structural evolution of the interstellar medium and the origins and pathways of matter in star-forming regions. The groundbreaking findings have been published in Nature Astronomy. Moving forward, the research team aims to further utilize the FAST telescope to conduct comprehensive observations of additional ultra-high-speed clouds, with the ultimate goal of uncovering the universal physical principles governing the formation of interstellar structures.
