Satellites Threaten Night Sky, Experts Warn

0:00Scientists are sounding the alarm on plans to light up the night sky with reflective satellites and up to 1 million more in low Earth orbit. Start a reflect orbital once the bound sunlight down to Earth using giant mirrors while SpaceX aims to build a massive orbital computing network for AI. Experts say this could mess with natural darkness on a global scale, hitting sleep cycles and ecosystems hard. Reflect orbital's mirrors would target spots 5 to 6 kilometers wide, cranking brightness from full moon levels to noon intensity for things like extending solar power or aiding disaster zones. SpaceX's swarm would cut energy needs for ground data centers by handling AI up there. Both need approval from regulators like the FCC. Leaders from groups like the European Biological Rhythm Society and World Sleep Society warn it could throw off human hormones, animal migrations, plant growth, and ocean food chains. They compare to climate change, saying night isn't just background, it's key to life.

1:01Dark Sky International adds that birds and bugs use stars to navigate and humans love that clear night view. Right now, existing satellites have bumped sky glow by about 10% with streets messing up telescopes and adding subtle brightness no one can. Escape, even in remote spots, models predicted could double or more by 2035 if launches keep up. The real worry, life detects these tiny changes way before we notice. These groups are pushing for full environmental checks and brightness caps before anything launches. With stakes this high for health, food security, and nature's clock, regulators have some heavy thinking to do. Sydney News, today powered by AI bringing you what matters. I'm Corey with the story.
