If you’ve ever watched Star Wars and wondered what life on Tatooine would really be like, here’s a question you probably never considered: What would a rainbow look like under two suns?
Rainbows form when sunlight passes through tiny water droplets, so a planet with two suns would produce something far more spectacular than the one we’re used to on Earth. Instead of a single rainbow (or the occasional double rainbow), a Tatooine-like world would create overlapping sets of rainbows, resulting in a dazzling celestial display that’s as beautiful as it is scientifically fascinating.
This fun video explains the real physics behind rainbows on a binary star planet, why Tatooine’s twin suns would create overlapping arcs instead of separate ones, and how that could even mean twice as many legendary pots of gold.
