Day 2 of #AAS244
First plenary: Dark and Quiet Skies for the Future of Astronomy and of the Space Environment, Aparna Venkatesan and Teznie Pugh, AAS Committee to Protect Astronomy and the Space Environment (COMPASSE).
The committee is trying to reduce the impacts of artificial light, EM interference, and satellite constellations.
The news is depressing. I will impact more than just astronomers: cultural sky traditions, environmental degradation, astrotourism, amateur astronomers, and more.
