The Sun doesn’t just shine—it also shapes the high-energy γ-ray sky by interacting with cosmic rays. Using 15 years of Fermi-LAT data, researchers detected the solar γ-ray halo in unprecedented detail and linked it to the same cosmic ray electrons measured near Earth. This study reveals how γ-ray observations can uncover the invisible influence of the Sun’s magnetic field across the heliosphere.
