    A recent study led by Dilda Berdikhan, a Ph.D. student from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences, has uncovered compelling evidence that a cloud–cloud collision has triggered active star formation in the molecular cloud G013.313+0.193 (hereafter G013.313) in the Milky Way. The findings are published in Astronomy & Astrophysics.

    Using observational data from the NanShan 26-m Radio Telescope and the Delingha 13...
