Imagine looking up at the night sky and seeing giant mirrors redirecting beams of sunlight straight down to Earth! In this episode, we explore a wild new technology that sounds like pure science fiction—but is fast becoming reality. California startup Reflect Orbital is planning a massive fleet of space mirrors, starting with their Eärendil-1 satellite, aiming to sell sunlight on demand to boost solar farms, light up night-time event venues, and help search-and-rescue crews in emergency zones.

However, astronomers and wildlife experts warn that polluting our night sky with reflected light could obscure deep-space research, disrupt natural animal behavior, and ruin stargazing forever. Is selling sunlight from space a brilliant energy innovation or a step too far? Australia's favorite astronomer, David Reneke, joins us to break down the science, the Desert tests, and the controversy in plain English!
