Chaotically Magnetized Cloud Is No Place to Build a Star, or Is It?
For decades, scientists thought that the magnetic field lines coursing around newly forming stars were both powerful and unyielding, working like jail bars to corral star-forming material. More recently, astronomers have found tantalizing evidence that large-scale turbulence far from a nascent star can drag magnetic fields around at will. Now, a team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has discovered a surprisingly weak and wildly disorganized magnetic field very near a newly emerging protostar, shown here in an artist’s impression. These observations suggest that the impact of magnetic fields on star formation is more complex than previously thought.
