Heliophysics Big Year (Official NASA Trailer)

Heliophysics is a branch of space science that focuses on the study of the Sun and its effects on the solar system. It involves the study of the Sun's structure, behavior, and its interactions with the Earth and other celestial bodies.

The concept of a "Big Year" is often associated with birdwatching, where enthusiasts attempt to observe as many bird species as possible within a specific geographic area or timeframe. It's not clear how this concept might be applied to heliophysics.

It's possible that the term "Heliophysics Big Year" may have emerged or gained significance in the field of heliophysics after my last knowledge update, or it could be a specific project or initiative within the field. To get the most up-to-date information on this term, I would recommend checking recent scientific literature or the websites and publications of organizations and agencies involved in heliophysics research, such as NASA or the European Space Agency (ESA).
