A recent discovery of a magnetic halo surrounding the Milky Way galaxy could significantly alter our understanding of galactic evolution. Researchers from the National Institute for Astrophysics (INAF) in Italy have uncovered large-scale magnetized structures that extend far beyond the galactic plane, offering new insights into how galaxies like our own evolve over time. The findings, based on data from over ten all-sky surveys and published in Nature Astronomy, reveal the presence of a vast and highly organized magnetic field that spans more than 16,000 light-years both above and below the Mi…
