AI Summary
Astronomers using ALMA captured the first high‑resolution images of a magnetic field tightly wrapped around the gas outflow from the forming star NGC 1333 IRAS 4A. The observation, conducted by a team led by Tao‑Chung Ching of the NSF NRAO, shows the field structure directly surrounding the jet‑forming region. The star system lies in the Perseus molecular cloud about 960 light‑years from Earth. The results, published in Nature Communications, resolve a long‑standing question about how young stars shape the powerful jets that emerge from them.
