About the Union

The International Astronomical Union (IAU) promotes and coordinates worldwide cooperation in astronomy. The IAU, through its nine divisions and 40 commissions covering the full spectrum of astronomy, plays a key role in fostering international collaborations. The international union brings together over 10,500 astronomers in 94 countries worldwide. U.S. astronomers are encouraged to engage in a number of IAU activities. 
 
Activities in the various astronomical sub-disciplines are mostly coordinated through the IAU divisions. The list of divisions is as follows:

  • Division A: Fundamental Astronomy
  • Division B: Facilities, Technologies and Data Science
  • Division C: Education, Outreach and Heritage
  • Division D: High Energy Phenomena and Fundamental Physics
  • Division E: Sun and Heliosphere
  • Division F: Planetary Systems and Bioastronomy
  • Division G: Stars and Stellar Physics
  • Division H: Interstellar Matter and Local UniverseDivision J: Galaxies and Cosmology
  • Division J: Galaxies and Cosmology
