A team of astronomers using ALMA has discovered a surprisingly weak and wildly disorganized magnetic field very near a newly emerging protostar. These observations suggest that the impact of magnetic fields on star formation is more complex than previously thought. The researchers used ALMA to map the magnetic field surrounding a young protostar dubbed Ser-emb 8, about 1,400 light-years away in the Serpens star-forming region. These observations are the most sensitive ever made of the small-scale magnetic field surrounding a protostar. They also provide important insights into the formation of low-mass stars like our own sun.
