I’m creating an Earth-like world where the inhabitants and visitors to the planet see the planet’s sun as blue in color. I think that the best way to achieve this result is via atmospheric light filtering. The atmosphere would scatter and absorb the longer wavelength red light from the planets sun, resulting in the sun appearing to be blue. In 2021 in Beijing, a sandstorm turned the sky yellowish, and the sun blue. (Linked to an article about it at the bottom). If I want to achieve this result on my Earth-like planet, would I have to have a perpetual, global sand storm to achieve this result, or could particles be suspended higher up in the atmosphere to achieve this result without needing perpetual sand storms? I need a scientific explanation for why the particles stay suspended in the atmosphere.
- The atmosphere must be hospitable to Earth-life (or any life form that lives on Earth). It can’t be harmful or detrimental to these forms of life.
- Because the atmosphere must be hospitable to Earth-life, the atmosphere’s composition should be similar to Earth’s.
- I don’t want an all-desert planet. I want to have trees, and forests, and other environments similar to Earth.
- The apparent color of the sun is due to atmospheric filtration. I’ve ruled out using a blue star due to too high of levels of UV light which would be harmful.
