A blue Sunset on Mars

blue-sunset-on-marsThe NASA’s Curiosity Mars rover captured images that shows the red planet has a blue sunset. The blue sky is due to the fine dust in the atmosphere according to the Curiosity team. Dust and fine particles in the atmosphere scatter the greens and blues from setting sun to color it red, orange and yellow. When the tints are reflected off the clouds, sunset colors are amplified and hence spread about the sky. The fine dust in the Martian atmosphere absorb blue light and scatters the warmer colors while the dust particles in the direction of the Sun scatter the blue light. The blue glows when the Sun is near the horizon, this is the time it passes through the greatest depth of atmosphere and dust.
