火星の夕焼けは青い？
On Earth, sunsets look red or orange, but on Mars, they appear blue. This happens because tiny dust particles in Mars’s atmosphere scatter blue light more than other colors. On Earth, the atmosphere allows red light to pass through more easily, making sunsets red. But on Mars, the effect is reversed. If you stood on Mars and watched the sunset, you would see a strange sight—an orange-red sky during the day turning blue in the evening.
