Modern science is a communal affair, with researchers joining into groups of all sizes for a single project or perhaps a career-long endeavor. Each field has its own standards and norms of practice, driven by history and funding patterns. Astronomers, broadly defined here to include astrophysicists, planetary scientists, heliophysicists, and physicists involved in astronomy, have an extremely long history and an eclectic funding pattern that includes private donors, government grants, and multi-national funding.
