Sunsets on Mars are Blue
Here, on our planet (that sounds weird to say, but that's what it's come to) the sunsets are usually a red or a golden color. On Mars, things are different. What color are sunsets on Mars? See for yourself.
The reason sunsets on Earth are in the red hues is because of the way light refracts off of gases and other particles in the atmosphere.
Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. So at sunrise and sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red and yellow light remaining. - Optics for Kids
Things are different on Mars. Different particles in the atmosphere, and different gases.
As you can see in the photo above, the sunset on Mars is of a blueish tint. It's the same Sun we see, of course, but it just looks different on Mars.
The website Space.com explains it this way:
In a 2014 study that used data from the Mars rover Spirit, Ehler and his colleagues found that Martian dust scatters light very differently than gas molecules do. "The reason for [the] blue sunset is the pattern in which light scatters off those [dust] particles," he said. - Space.com
I am guessing that, on vacation in the next 30 years or so, some of us may very well be holding space-gloved hands, enjoying a sunset through the front windshield of our Marsabago.
