Astronomers Warn Against Satellite Reflecting Sunlight at Night

The night sky, once a pristine canvas for astronomers and dreamers alike, is facing a modern challenge: the rise of artificial light from space.
A growing debate has emerged between the 'new space' economy, which champions innovation, and the scientific community, which fights to preserve the darkness of our cosmos.
At the heart of this conflict is the startup Reflect Orbital, which plans to deploy satellites equipped with giant mirrors to beam sunlight back to Earth at night.
While proponents argue this could boost solar energy or assist in disaster relief, astronomers warn of severe consequences.
This issue is compounded by the proliferation of massive communications satellites, such as AST SpaceMobile's BlueWalker 3, which are so bright they frequently outshine the stars.
Because current space regulations often ignore light pollution in favor of radio frequency management, the night sky is becoming a site for a 'tragedy of the commons.'
As private companies reshape our view of the heavens, the global community must decide how to balance technological progress with the preservation of our shared celestial heritage.
