Sep 23, 2020 · Yellow is caused by charged paticles in the solar wind striking oxygen high in the atmosphere. The oxygen then emits yellow light. This happens constantly on your planet. Because of the near constant haze, the pure yellow light emitted by oxygen is diffracted in the haze, such that the entire sky glows yellow. Share.
3. Most colors would be possible. The two items that determine what color the sky is is the color of the sun and what is in the atmosphere. Having a red star will be the easiest in making the the sky shades of red, since that is the primary wavelengths coming from the star. The rest, it depends on what is in the air to both absorb certain light ...
(Ah, and our Sun is not yellow. It is white with a very very very slight yellow tinge. The same would go for a "blue" star -- it would be white, with a very very very slight blue tinge. Only a red star can be truely red, but then if it were as small in the sky as our Sun it would be so much less luminous that the sky would appear black ...
If it's a really dim red dwarf (like an M8) your sky might take on a somewhat orange/brown tinge even at noon (due to sever lack of longer-wavelength light). Noon: A darker, greyish-blue (maybe brownish-orange) at zenith getting whiter/grey towards the horizon. The sky overall is much darker in color than Earth's.
Aug 25, 2022 · So a planet with a thick (earth like) atmosphere, orbiting close to a red or orange star would have a green sky. If you need the air to explode with the addition of oxygen then the atmosphere could consist of hydrocarbons (methane, ethane..), as such gasses would burn/explode when mixed with oxygen. hopefully that helps.
May 24, 2015 · The red star's light will contain many different frequencies of visible light, and should have enough blue light for atmospheric scattering to make the sky dark blue. But the vast amount of red light from the red star should also cause a lot of red light to be scattered by the sky, perhaps making the sky appear purplish.
Jul 9, 2020 · 6. Every sky, even sky on Mars or Jupiter tend to be blue. If you atmosphere is Earth-like it will be blue. Only sunsets and sunrises would add some tints to horizon, but it still would be more or less red (and would add redish tint to suns) Reason is simple: color of a sky is defined by Rayleigh scattering. Share.
Feb 15, 2016 · Purple is probably possible with a slightly hotter sun and some atmospheric dust that absorbs yellow and green light. Light Source. The reason our sky is blue is because of Rayleigh scattering, which preferentially scatters shorter-wavelength (higher frequency, higher energy, blue-er) light.
Please describe any notable differences in flora/fauna between Earth and a comparable planet with a red sky. For the topic of this discussion, assume all other properties of the planet are similar or identical to those of Earth. In case it's important, I'm building an alien world with a red sky and mountainous, spiky terrain.
If the planet's sun was very hot, the sky would look a deeper blue, while cooler stars would give the sky a lighter blue to almost white look. When the sun gets to 3000k and below, the sky starts to take on an orange/brown tinge. Like on earth, the horizon is the lightest in color and the zenith the deepest.
