Blue Martian Sunset

Earth is a blue planet that has red sunsets. Mars is a red planet with blue sunsets!

From its vantage point on the surface of Mars, NASA’s rover Opportunity relayed a spectacular series of images of a blue-hued sunset on the red planet. Scientists then stitched the pictures, taken over a period of 17 minutes, into a 30-second movie simulation.
The bluish glow around the sun is due to the same dust particles that make Mars’ sky appear red. The pictures were taken on Nov. 4 and Nov. 5 using three different filters on the rover’s panoramic camera.
