Cloud–cloud collision sparks active star formation in Milky Way

Cloud-cloud collisions reshape molecular clouds and trigger star formation

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...

Stellar Nursery Blooms into View

The OmegaCAM imager on ESO's VLT Survey Telescope has captured this glittering view of the stellar nursery called Sharpless 29. Many astronomical phenomena can be seen in this giant image, including cosmic dust and gas clouds that reflect, absorb, and re-emit the light of hot young stars within the nebula. Credit: ESO/M.

The OmegaCAM camera on ESO’s VLT Survey Telescope has captured this glittering view of the stellar nursery called Sharpless 29. Many astronomical phenomena can be seen in this giant image, including cosmic dust and gas clouds that reflect, absorb, and re-emit the light of hot young stars within the nebula. The region of sky pictured is listed in the Sharpless catalogue of HII regions: interstellar clouds of ionised gas, rife with star formation...
