No, not all planets have blue skies.
While Earth's sky is blue due to Rayleigh scattering, the atmospheric composition of other planets dictates their sky's color.
Here's a breakdown:
- Earth: Blue sky.
- Saturn: According to research, ice crystals made of a chemical called ammonia in Saturn's upper atmosphere make it a pale shade of yellow.
- Uranus: Uranus' atmosphere also contains some ammonia, which makes the planet a slightly greener shade than the deep blue we see on Neptune.
- Neptune: Deep Blue.
- Jupiter: Has a different-colored atmosphere.
This demonstrates that sky color varies based on the specific gases and particles present in a planet's atmosphere, not all planets have blue sky like Earth.
