5G satellite becomes one of the brightest objects in the night sky, raising concerns for astronomers

BlueWalker 3, a prototype 5G satellite launched by AST SpaceMobile, is now one of the brightest objects visible in the night sky.
The satellite's large size and reflective antenna array make it shine brighter than all but a handful of stars and planets.
Astronomers warn the increasing number of bright satellites could interfere with observations and change our view of the night sky.
BlueWalker 3 exceeds maximum brightness recommendations from astronomers by hundreds of times.
There are calls for satellite companies to mitigate brightness and consider the impact on astronomy before launching more prototypes.
