The Parker Solar Probe, launched by NASA in 2018, has made groundbreaking discoveries about the Sun, advancing our understanding of solar phenomena. This mission marked humanity’s closest approach to a star, traveling through the Sun's corona (its outermost atmosphere) to gather unprecedented data. It confirmed the presence of "switchbacks," sudden reversals in the Sun's magnetic field, which help explain the mysterious heating of the corona to temperatures far hotter than the solar surface. The probe has also unveiled new insights into solar wind acceleration, revealing that particles escape the Sun at higher speeds than previously estimated, impacting space weather forecasts. Furthermore, Parker has identified dynamic processes near the Sun that influence heliophysics, including the behavior of solar flares, coronal mass ejections (CMEs), and energetic particles, offering key details about their origins and potential impacts on Earth. These discoveries enhance our understanding of how the Sun’s activity shapes the solar system and provide valuable data for protecting satellites and electrical grids from solar storms.
