📡"Magnetic Superhighways Discovered in a Starburst Galaxy’s Winds" by National Radio Astronomy Observatory (NRAO)
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has mapped a magnetic highway driving a powerful galactic wind into the nearby galaxy merger of Arp 220, revealing for the first time that its fast, molecular outflows are strongly magnetized and likely helping to drive metals, dust, and cosmic rays into the space around the galaxy. By watching how tiny dust grains and gas molecules line up with these fields, researchers have drawn the most detailed magnetic map yet of Arp 220’s buried, star‑forming cores and their outflows. The result is a new way to see how gravity, starbirth, black holes, and magnetic forces all work together in a chaotic cosmic environment.
