The IAU, through its 12 Scientific Divisions and 40 Commissions covering the full spectrum of astronomy, plays a key role in fostering international collaborations. The international union brings together over 8,600 astronomers from 84 countries. U.S. astronomers are encouraged to engage in a number of IAU activities.
