Inside the vast Universe, in a galaxy among several stars there exists a very special place with life. Its our Earth. Earth is also known as blue planet, but there is also a red planet where life could be possible. Mars is a scary desert while Earth is full of water, greenery and life. Their is another surprising difference. The sky on Mars is red while sunsets are blue.

The Reason
The reason is very similar to the reason that why sky on Earth is blue and sunsets are red. Sunlight comprises of various wavelengths, which scatters while travelling through atmospheric molecules and dust particles. This scattering defines the color that we see in sky and during sunsets.
Mars has a very thin and light atmosphere, about 1 percent of Earth's. It is made up of Carbon dioxide and has a lot of dust. The fine dust present in Martian atmosphere tends to scatter light so that red color splash everywhere while blue color pass gently. And thus the sky looks reddish in Mars. At sunset light has a longer way to travel thus the red color scatter very much while the blue passes gently. Due to fire flares and amplification be ash of volcanoes we see red color on Earth's Sunset whereas on Mars we get a cool blue hue.
The End Notes
Curiosity, Spirit, and Opportunity robotic rovers we've sent to the Mars, have witnessed and recorded the curious phenomenon. Earth and Mars are the only two places in the Solar System that have sunsets that we can observe. That's all in this post. Please leave your views on comment section.
