Why is Mars red?
Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.

Which is the brightest planet in the universe?

Is it bad if the sun is red?
The red color is caused by sunlight being scattered due to particles and aerosols in the atmosphere when the sun sits low in the horizon. Not every fiery sunrise is a sign of coming storms, but the science says it may be indicative specifically for weather systems moving from west to east in mid-latitudes.
Why is the sun turning red?
The smoke essentially acts as an Instagram filter for the sky — sunlight naturally interacts with very small particles in the atmosphere and scatters colors in the visible spectrum; with more scattering taking place than usual, red (the color with the longest wavelength) appears more prominently.
Why is the sun so red today 2020?
When particles, such as smoke or dust, fill the atmosphere, the longer wavelengths of light — which look red — scatter more effectively. If the air is cleaner, there are more air molecules, which scatter shorter wavelengths or light, or blue light, more effectively. (Think clear blue sky.)
