🚨 Beyond the limit 🚨  New ESO study finds that current proposals to launch 1.7+ million satellites into orbit would have devastating consequences for astronomy. The most extreme proposals come from SpaceX & Reflect Orbital  🔭 🧪 ☄️ #DarkSkies #SatelliteConstellations 1/4

SpaceX plans to launch 1 million satellites for space-based data centres.  This diagram shows the satellites that would be visible above our VLT: ⚪ invisible satellites in Earth’s shadow 🟠 2000 satellites brighter than magnitude 7  🔴 200 satellites brighter than magnitude 5 🔭 🧪 ☄️ #DarkSkies 2/4

Reflect Orbital aims to launch 50,000 mirror-like satellites to provide sunlight at night, with reflected beams spanning at least 5 km on Earth's surface. This image illustrates how scattered sunlight would increase the overall brightness of the sky above the VLT. 🔭 🧪 ☄️ #DarkSkies 3/4
