Abstract

The International Astronomical Union (IAU) is the international organisation that represents the astronomical community. The members are professional astronomers and organizations representing national astronomical communities. The main goals of the Union are promoting and safeguarding astronomical research, communication, education, and development through international cooperation1 . The International Astronomical Union embraces the principle of a dark and radio quiet sky, that the Union considers fundamental for all humanity. Indeed, a dark and radio quiet sky is essential to advance our knowledge of the universe, and to protect nocturnal wildlife, and it is a cultural resource for humankind too2 . To address the problem of pollution at all wavelengths of the electromagnetic spectrum from artificial sources, the International Astronomical Union established a specific commission, that is focused on the reduction and prevention of sky glows and radio frequency interference on astronomical research facilities3 . In recent years, new actors have emerged on the scene: the satellite constellations, that are networks of artificial satellite orbiting around the Earth. These new satellite constellations were born to offer communication services for humankind, but they pose new challenges and issues to the astronomical community. Indeed, recent studies pointed out that they can be detrimental for optical and radio astronomy. Considering the purposes of the International Astronomical Union and considering the effects on astronomy of the new satellite constellations, the aim of this thesis is to analyse the actions and the communication regarding the new satellite constellations of the International Astronomical Union, as the recognized international association of astronomers. The structure of this text is as follows. The first two chapters set the frame for the research question. Particularly, Chapter 1 outlines the main features of the International Astronomical Union. Instead, Chapter 2 sets the background of the new satellite constellations. After this part, in Chapter 3, we describe the methodology that we adopt in this research. Then, in Chapter 4, we present our results. Finally, in the Conclusions we highlight our findings.
