天文學家警告衛星在夜間反射陽光的問題
Astronomers Warn Against Satellite Reflecting Sunlight at Night

夜空曾是天文學家與夢想家眼中純淨的畫布，如今卻面臨一項現代挑戰：太空人造光的興起。「
The night sky, once a pristine canvas for astronomers and dreamers alike, is facing a modern challenge: the rise of artificial light from space.
新太空」經濟提倡創新，而科學界則竭力捍衛宇宙的深邃黑暗，兩者之間的辯論日益激烈。
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.
這場矛盾的核心在於新創公司 Reflect Orbital，該公司計畫部署配備巨型鏡面的衛星，在夜間將陽光反射回地球。
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.
儘管支持者認為這能提升太陽能效益或協助救災，但天文學家警告這將帶來嚴重後果。
While proponents argue this could boost solar energy or assist in disaster relief, astronomers warn of severe consequences.
除了使用望遠鏡的觀測者有視網膜受損的風險外，增加的「天空輝光」更威脅到深空觀測。
Beyond the risk of retinal damage for those using telescopes, this added 'sky glow' threatens to obscure deep-space observations.
此問題因大量通訊衛星（如 AST SpaceMobile 的 BlueWalker 3）的增殖而更趨嚴重，這些衛星過於明亮，常常蓋過星光。
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.
由於現行太空法規往往忽略光害問題，而側重於無線電頻譜管理，夜空正逐漸淪為「公地悲劇」的場域。
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.'
