May the Force (4th) be With you....Pictured here is the blue Sunset on Mars from the Mars Exploration rover.
The reason for blue is that the large dust particles in the Martian atmosphere scatter the blue portion of sunlight in one direction but the red portion of it in a broader formation. Blue light appears concentrated and is 6 times as intense as red light. This is why sunsets and sunrises on Mars are blue.
We need Celtic Moon broadcasting on Mars! ;D
