Seeing this cosmic artifact could give astronomers some vital clues to how the magnetic fields of galaxies like the Milky Way came to be.
. When this happens, the light waves oscillate along a preferred direction instead of randomly. When ALMA detected and mapped the more polarized signal coming from galaxy 9io9, it confirmed the presence of a magnetic field in a very distant galaxy for potentially the first time.
The team hopes that with this new discovery and future observations of distant magnetic fields, astronomers will get closer to how fundamental components of galaxies form. Laura is a science news writer, covering a wide variety of subjects, but she is particularly fascinated by all things aquatic, paleontology, nanotechnology, and exploring how science influences daily life.

JWST Gazes into the Dark Molecular Clouds at the Heart of the Milky WayThere’s an unusual object near the Milky Way’s heart that astronomers call “The Brick.” It’s a massive cloud of gas called an infrared dark cloud (IDC). The Brick is dense and turbulent like others of its type, but for some reason, it shows few signs of star formation. Why? The Milky Way’s Central Molecular Zone … Continue reading 'JWST Gazes into the Dark Molecular Clouds at the Heart of the Milky Way'
