The high altitude clouds serve to reflect strongly reddened sunlight still striking the stratosphere after sunset, down to the surface. Some of the most varied colors at sunset can be found in the opposite or eastern sky after the Sun has set during twilight. Depending on weather conditions and the types of clouds present, these colors have a wide spectrum, and can produce unusual results.

The 16th-century astronomer Nicolaus Copernicus was the first to present to the world a detailed and eventually widely accepted mathematical model supporting the premise that the Earth is moving and the Sun actually stays still, despite the impression from our point of view of a moving Sun.
Sunsets on other planets appear different because of differences in the distance of the planet from the Sun and non-existent or differing atmospheric compositions. On Mars , the setting Sun appears about two-thirds the size it appears on Earth  because of its greater distance from the Sun.
The colors are typically hues of blue, but some Martian sunsets last significantly longer and appear far redder than is typical on Earth.
Mars has a thin atmosphere , lacking oxygen and nitrogen , so the light scattering is not dominated by a Rayleigh Scattering process. Instead, the air is full of red dust , blown into the atmosphere by high winds,  so its sky color is mainly determined by a Mie Scattering process, resulting in more blue hues than an Earth sunset.
One study also reported that Martian dust high in the atmosphere can reflect sunlight up to two hours after the Sun has set, casting a diffuse glow across the surface of Mars.
