What to know about Twisted magnetic field around newborn star confirms decades-old jet theory

Astronomers using the ALMA telescope have captured high-resolution images of a toroidal magnetic field surrounding a newborn star system, NGC 1333 IRAS 4A. The findings provide direct evidence for a long-standing theory regarding how magnetic fields shape the jets and outflows of gas during star formation.

Common ground

The findings, from a research team led by Tao-Chung Ching, a former Jansky Fellow at the NSF NRAO, focus on NGC 1333 IRAS 4A, a young double-star system embedded in the Perseus molecular cloud, roughly 960 light-years from Earth.
