Fine Martian dust scatters red light while allowing blue light to pass through

While Earth's atmosphere scatters blue light to produce red sunsets, Mars experiences the opposite effect. The fine iron-rich dust suspended in the thin Martian atmosphere scatters blue light more efficiently towards an observer, creating a blue glow in the sky surrounding the setting Sun.
