Story summary

Astronomers at NSF’s Very Large Array have made a groundbreaking discovery near HW2, a protostar in the Cepheus A region, located 2,283 light-years away. They observed a remarkable gas flow, revealing that massive stars can form through disk-mediated accretion at an infall rate of two thousandths of a solar mass per year, reshaping our understanding of star formation and galaxy evolution.
