@starwalkapp: Mars may be the Red Planet… but its sunsets glow blue 💙🌅 On Earth, sunsets look red and orange because our atmosphere scatters blue light. On Mars, the dusty atmosphere behaves differently: during sunset, red light is scattered out across the sky, while blue light is scattered forward more strongly near the Sun. So the sky farther from the Sun can look reddish, but the area right around the setting Sun can glow blue. So Mars flips the sunset colors we’re used to: 🔴 daytime sky = usually butterscotch or reddish 💙 sunset = blue halo or blue glow Rovers like Curiosity and Perseverance have actually photographed these blue Martian sunsets, so this isn’t just a theory — it’s something we’ve seen with cameras on the planet itself. Would you like to watch a blue sunset on Mars? 🚀 #mars #earth #space #Astronomy #starwalk
