The Heliophysics Big Year is a NASA-led public engagement campaign designed to promote heliophysics broadly, make heliophysics science and information accessible to all, and showcase ongoing efforts to understand the Sun and all that it touches. We are challenging the public to participate in as many Sun science activities as possible from October 2023 to December 2024, leading up to and around solar maximum.
