The Heliophysics Big Year is a global celebration of solar science and the Sun’s influence on Earth and the entire solar system. Join us October 2023 to December 2024!
What is the Heliophysics Big Year?
During the Heliophysics Big Year, you will have the opportunity to participate in many solar science events such as watching solar eclipses, experiencing an aurora, participating in citizen science projects, and other fun Sun-related activities.
What is heliophysics?
Heliophysics is the study of our star and how it interacts with everything in our solar system.
What is a Big Year?
The “Big Year” is a concept that originated with citizen scientists in the bird-watching community. During their Big Year, birders attempt to observe and study as many bird species as possible during a calendar year, and we are challenging you to do the same with our Sun.
Can groups outside of NASA contribute to the Heliophysics Big Year?
Yes! We are inviting all those interested in sharing the science, art, and beauty of heliophysics to participate in the Heliophysics Big Year. We have created an identifier as a way to tie together the collective efforts of the entire heliophysics community into one cohesive brand. Anyone supporting the Heliophysics Big Year effort may use these resources in accordance with the style guide. You can download the style guide and identifier on the assets page.
