Introducing The Heliophysics Big Year

In October 2023, NASA is launching the Heliophysics Big Year – a global celebration of solar science and the Sun’s influence on Earth, our solar system, and beyond. Modeled after the “Big Year” concept from citizen scientists in the bird-watching community, the Heliophysics Big Year challenges everyone to get involved with Sun-related activities. The Heliophysics Big Year begins in October 2023 and runs through December 2024.
