JWST Reveals Strong Magnetic Fields Suppress Star Formation at Milky Way's Center

Observations using the James Webb Space Telescope (JWST) indicate that strong magnetic fields at the center of the Milky Way are inhibiting star formation, despite the presence of ample gas and dust. This study focuses on the Central Molecular Zone (CMZ), a region known for its high concentration of star-forming materials, yet exhibiting a surprisingly low rate of star birth. For the first time, scientists have directly observed the significant role that powerful magnetic fields play in suppressing star formation in this region. The findings combine data from JWST and the MeerKAT radio telescope, revealing interstellar dust clouds and gas streaks sculpted by magnetic fields around Sagittarius A*, the supermassive black hole at the Milky Way's heart. These magnetic fields appear to be strong enough to counteract the gravitational forces that would normally cause gas and dust to collapse and form new stars.
