International Astronomical Union (IAU)

The International Astronomical Union (IAU), established in 1919, plays a pivotal role in promoting and safeguarding astronomy through international cooperation. It addresses significant challenges such as the impact of satellite constellations on astronomical observations, highlighted by recent actions like the UN addressing this issue and the establishment of a new center to mitigate these effects. The IAU also fosters global engagement in astronomy, as seen in activities like the naming of exoplanetary systems and hosting the General Assembly in Africa for the first time, emphasizing accessibility, impact, and sustainability. With over 13,500 members from more than 100 countries, the IAU encourages collaborative efforts among astronomers, industry, and policymakers to overcome challenges and innovate in observation and data analysis techniques, ensuring the continued exploration and understanding of the cosmos.
