This is an artistic concept of NASA's effort to explore and celebrate the Sun's influence on everything through an effort called the Heliophysics Big Year. The Heliophysics Big Year is a global celebration of solar science and the Sun's influence on Earth and the entire solar system. The Heliophysics Big Year began Oct. 14, 2023, with an annular solar eclipse, includes a total solar eclipse on April 8, 2024, and culminates with Parker Solar Probe's closest approach to the Sun on Dec. 24, 2024.
