TL;DR Summary

BlueWalker 3, a prototype communications satellite with a large antenna, has become one of the brightest objects in the night sky, causing concern among astronomers. The satellite's brightness exceeds the International Astronomical Union's guidelines and poses a threat to observatories and astronomical research. With the increasing proliferation of satellites, including constellations like Starlink, the night sky is becoming crowded, and the cumulative effect of these satellites could transform the natural view of the sky. Astronomers are calling for active satellite tracking and avoidance strategies to mitigate the impact on ground-based telescopes. Collaboration between the space industry and the astronomy community is crucial to finding solutions to this growing problem of light pollution from satellites.
